Truck blind spot accident claims

These are the claims where the injured person is most often told the crash was their own fault for being somewhere the driver could not see. It is worth knowing early that federal law does not treat a restricted view as a driver's license to change lanes. It requires equipment positioned to show the highway along both sides of the vehicle, which is a rule about what the driver must be able to see rather than about what they happened to.

Key takeaways

  • A restricted view is a known condition, not a surprise. It is mapped, taught, and the subject of an equipment requirement.
  • The rule is about visibility, not hardware. Mirrors must be positioned to show the highway along both sides, which is a standard about the resulting view.
  • Being unseen is not the same as being at fault. Those are separate questions and the second does not follow from the first.
  • The geometry is recoverable. Where each vehicle was, and what a correctly adjusted mirror would have shown, can be reconstructed.
Editorial content, not legal advice

This guide is written and reviewed by our editorial team to be accurate and current. It is general information, not legal advice, and reading it does not create an attorney-client relationship. The regulation quoted below comes from the Code of Federal Regulations and is linked. How responsibility is divided where both parties contributed is a matter of state law and varies considerably. We are a referral service and are paid by attorneys.

01 The four areas, and why they differ

Quick answer

A tractor and trailer has restricted vision immediately in front of the cab, along both sides, and directly behind the trailer. These four areas are commonly called the no-zone, and they are not the same size as each other or equally difficult to check.

Understanding which one you were in matters, because the driver's ability to have seen you differs enormously between them.

  • Directly in front. The height of a cab means a vehicle close ahead can drop out of view. Relevant to rear-end impacts and to pulling away at lights.
  • The left side. Smaller, because the driver sits on that side and the angle is more favorable.
  • The right side. The largest by a wide margin, extending back and outward across more than one lane. Most of these collisions happen here.
  • Directly behind. A long trailer hides a considerable distance, which matters when a truck reverses or stops abruptly.

A no-zone accident is therefore not a single kind of event. A collision on the right during a lane change and a strike while reversing raise different questions about what the driver could and should have done.

02 Why a blind spot is not a defense

Quick answer

Expect to be told that you were in the driver's blind spot, as though that settled matters. It does not. The existence of restricted vision is precisely why a professional operator is required to have mirrors, to adjust them, to check them and to move only when the way is clear.

This argument is powerful because it sounds like an explanation and functions like an excuse. Separating those two things is most of the work in these cases.

Consider what the assertion actually claims. It says the driver could not see you. Accept that for a moment. It does not follow that the driver could not have seen you, that the mirrors were properly adjusted, that they were checked before the maneuver, that a signal was given and held, or that the driver waited long enough to be sure. Every one of those is a separate question, and every one is about the driver's conduct rather than yours.

Bottom line: a restricted view is the reason for the duty. It is not a discharge of it.

03 What the equipment rule actually demands

Quick answer

Federal regulation requires two mirrors on every bus, truck and truck tractor, and it does not stop at requiring their presence. It specifies where they must be positioned and what they must show, which makes it a standard about the driver's view rather than about hardware.

That distinction is the reason this provision is worth quoting in full rather than summarising.

Not just mirrors, but a view
Along both sides of the vehicle
49 C.F.R. 393.80(a)

The rule provides that every bus, truck, and truck tractor shall be equipped with two rear-vision mirrors, one at each side, firmly attached to the outside of the motor vehicle, and so located as to reflect to the driver a view of the highway to the rear, along both sides of the vehicle. It adds that such mirrors and their replacements shall meet, as a minimum, the requirements of FMVSS No. 111 in force when the vehicle was made. Read the operative words again: so located as to reflect to the driver a view. The obligation is expressed in terms of the resulting view, not the presence of glass. Read section 393.80

The rule carries three narrow exceptions. Mirrors fitted to vehicles built before 1981 may stay in service subject to a condition on replacement. Only one outside mirror, on the driver's side, is required on trucks built so that the driver has a view to the rear through an interior mirror. And in driveaway-towaway operations the driven vehicle needs at least one mirror giving a clear view to the rear. None of those describes an ordinary modern tractor unit on a highway.

04 The right side, and the right turn

Quick answer

The area of restricted vision on the right is much larger than on the left, and a long vehicle turning right often swings left first to make the corner. To a following road user that looks like an invitation into a gap that is about to close.

This combination produces a distinct kind of collision that is worth naming, because it is frequently misdescribed in the paperwork.

  • The wide swing. A vehicle moving left before turning right creates an apparent gap on the inside that is not a gap at all.
  • Cyclists and motorcyclists. Disproportionately affected, because they can occupy that space entirely.
  • The signal question. Whether one was given, when, and whether it was consistent with the initial movement, is central and often disputed.
  • Misrecorded as a sideswipe. A crossing collision during a turn gets logged as a lane change contact, which frames it wrongly from the start.

05 What a claim has to establish

Quick answer

Not that the driver saw you, which is usually unprovable, but that a driver taking the care required of a professional would have. That is a question about mirrors, checks, signalling and timing, all of which leave traces.

Framed that way the case stops being about your position and starts being about their procedure. That reframing is the single most valuable thing anyone can do early in a truck blind spot accident claim.

  • Mirror condition and adjustment. Present, undamaged, and set where they were supposed to be.
  • What a correct mirror would have shown. Reconstructable from the vehicle, the geometry and where each party was.
  • Signalling and timing. Whether the maneuver was announced, and whether the driver allowed time for it to be seen.
  • Training and the carrier's own standards. What the company taught about this maneuver, and whether it was followed.
  • How long you were there. A vehicle alongside for several seconds is a different matter from one that arrived in an instant.

Our guide to commercial truck accident claims covers how those records are obtained.

06 If you are told you share the blame

Quick answer

You may well be told you lingered where you should not have. Whether that reduces a claim, and by how much, is a question of state law, and in most states a share of responsibility reduces recovery rather than ending it.

The rules differ enough between states that the same facts can produce very different outcomes, which is a reason for advice rather than for despair. It also means a no-zone accident that would be worth pursuing in one state may be assessed quite differently a few miles across a border.

  • Most states apportion. Responsibility is divided and the award adjusted, so a share of blame is not usually the end of a claim.
  • Some impose a threshold. Where a claimant's share crosses a stated proportion, recovery can be barred, and the proportion varies.
  • A minority are stricter still. Which is precisely why an early admission to an adjuster is a bad idea wherever you live.
  • The apportionment is argued, not announced. An insurer's opening position on your share is a negotiating stance.

07 The evidence

Quick answer

Many commercial vehicles now carry forward and side-facing cameras, and most record continuously onto storage that is reused. Combined with the physical geometry of both vehicles, that footage frequently answers the question outright.

Where it exists it is decisive, which is exactly why the request for it needs to go out before anybody has decided whether to bring a claim.

  • Onboard camera footage. Forward, side and sometimes driver-facing, usually on a short rolling cycle.
  • The mirrors themselves. Their condition and position before anything is straightened or replaced.
  • Vehicle data. Speed, steering and signal use in the seconds before contact.
  • Damage geometry on both vehicles. Which shows the angle of contact and therefore the relative positions.
  • Nearby cameras. Junction, transit and business cameras that never belonged to either party.
The request that has to go early

Ask in writing, as soon as the carrier is identified, that camera footage be downloaded and preserved rather than left to overwrite, that vehicle data be retained, and that both vehicles be held unrepaired. Footage loops are frequently measured in days. A truck being repaired and returned to service is not misconduct, and it removes the mirrors in the state they were in.

08 What to do in the first days

Quick answer

Get medical care, record the geometry while you still remember it precisely, and get a written preservation request out for the camera footage. Say as little as possible about your own position until you have advice.

Five steps. The second one is the one people lose within a week.

1

Get medical attention and keep going

The treatment record is the injury record. Side impacts from a large vehicle produce injuries that present late, particularly to the neck and shoulder.

2

Write down the geometry immediately

Which lane you were in, how long you had been alongside, where the cab was relative to you, whether a signal showed and when. Precise memory decays within days.

3

Send a written preservation request

Camera footage first, because it overwrites, then vehicle data, mirrors and both vehicles unrepaired. Keep a copy and note the date sent.

4

Photograph both vehicles and the junction

The damage on each, the mirrors, and the layout including lane markings and sightlines. If it was a turn, photograph the corner itself.

5

Take advice before any recorded statement

You will be asked where you were and for how long. If the injuries are severe, our guide on what to do after a catastrophic accident covers the wider ground.

09 Red flags

Quick answer

The blind spot offered as a complete answer, footage said to be unavailable without any written request having been made, an early demand for a recorded statement about where you were, and a crash report describing a turning collision as a sideswipe.

Three of those four are about controlling the account of where you were before anybody checks.

How these claims get lost

The blame framing accepted. Once everyone agrees the case is about your position, nobody is examining the driver's procedure. Footage quietly gone. Not deleted, just overwritten in the ordinary course, which is what happens when nobody asks. The statement taken early. A guess at how many seconds you were alongside becomes a fixed fact for the rest of the claim. The report misdescribes it. A right turn collision logged as a lane change is a different case on paper from the one that happened.

One closing thought about any truck blind spot accident. The whole dispute usually turns on a single implied step: from the driver did not see you, to therefore it was your fault. That step is an assumption rather than a conclusion, and the regulation quoted above is one reason it does not hold. A free case review costs nothing, our guide to choosing a truck accident lawyer sets out what to look for, and you can read how we match people with attorneys before deciding anything.

How we vet every lawyer

This is a standard rather than an ordering. An attorney either clears it or does not.

  • Active, discipline-free license

    Verified good standing with the state bar, with no unresolved discipline on record. You can check this yourself too.

  • Willingness to fight the blame

    A record of contesting comparative fault rather than accepting an insurer's opening view of your share.

  • Capacity to fund expert work

    Sightline and reconstruction evidence is expensive and arrives early. The firm has to be able to carry it.

  • Clear contingency terms

    Fees and case costs put in writing up front, so you know exactly how it works before signing.

Tell us what happened and we will only match you when a case genuinely fits.

The equipment rule described here is federal and applies nationwide. What decides the outcome of an argument about shared blame is state law, and it varies more than almost anything else in this field. Some states reduce an award in proportion to a claimant's share, some bar recovery once that share crosses a threshold, and a small number are stricter again. Because these are the claims where blame is most often raised, where the crash happened can matter as much as what happened. The deadline for bringing a claim, known as the statute of limitations, is running now.

Sources and authorities

The regulation is quoted from the Code of Federal Regulations and linked.

Mirror requirements

  • 49 C.F.R. 393.80, Rear-vision mirrors. Source of the requirement quoted above that every bus, truck and truck tractor carry two rear-vision mirrors positioned so as to reflect to the driver a view of the highway to the rear along both sides of the vehicle, of the reference to Federal Motor Vehicle Safety Standard No. 111, and of the three exceptions described. Cornell Legal Information Institute.

Why this rule and not another. The provision is quoted because of how it is worded. It does not simply require mirrors to be fitted; it requires them to be located so as to produce a particular view. That makes visibility the subject of the obligation, which is directly relevant when an operator says the collision happened because they could not see. Whether the mirrors on a particular vehicle achieved what the rule describes is a question of fact.

A spelling worth mentioning. The third exception concerns what section 390.5 defines as a driveaway-towaway operation, and we have used that defined spelling because it is the one a reader looking the term up will find. Section 393.80 itself renders it slightly differently. We have not reproduced the variant inside a quotation, and the difference is orthographic rather than substantive, but we would rather say so than silently tidy a regulation.

What we have left out. We have given no figure for how many collisions involve areas of restricted vision, because no federal source we read this session provided one we could state precisely. We have said nothing about the legal status of camera systems fitted in place of mirrors: requests to permit that substitution have been made to the regulator, and we did not read whether any were granted, so we have not described the position. Side underride, which can follow a collision of this kind, is dealt with separately on this site. And we have reproduced no material published by trade associations or safety institutes, which is their copyrighted work rather than public law.

Our editorial standards

How we keep this guide accurate and worth trusting.

01

Public law only

The regulation is quoted and linked. No trade body's or institute's prose is reproduced here.

02

We name the argument you will face

Rather than describing the crash in the abstract, the guide addresses the specific thing you will be told.

03

Our gaps are named

No frequency figures, and nothing on the status of camera systems, because we had no source we had read.

04

State variation is flagged, not flattened

Shared blame rules differ sharply, so we describe the range rather than presenting one state's approach as the rule.

Common questions, answered

General information, not legal advice. What a claim recovers and how long you have are set state by state, so check anything here against your own state and your own attorney.

The driver says I was in his blind spot. Does that mean it was my fault?

No, and this is the assumption these cases turn on. Saying a driver could not see you is not the same as saying nothing could have been done. Restricted vision around a large vehicle is a known, mapped condition, which is precisely why a professional operator carries mirrors, is trained to use them, and is expected to move only once satisfied the way is clear. The real questions are about that procedure, not about your position.

Are truck mirrors actually required by law?

Yes, and how the requirement is phrased matters more than the fact of it. Two are required, one on each side, fixed to the outside of the vehicle. Crucially the rule then specifies where they must sit and what they must show, using the words along both sides. An operator therefore cannot satisfy it merely by having mirrors bolted on; the mirrors have to deliver the view. Whether a particular vehicle achieved that is a question of fact, and a question worth asking.

Which blind spot is the most dangerous?

The right side, by a considerable margin. It extends further back and further out than the left, often across more than one lane, and the driver sits on the opposite side of a wide cab. Add the fact that a long vehicle turning right frequently swings left first, and the result is a space that looks safe to a following road user at precisely the moment it is about to be occupied.

The truck swung left and then turned right into me. What is that?

It is a distinct kind of collision and it is often written up wrongly. Long vehicles need the extra width to get round a corner, so moving left before turning right is normal driving rather than a mistake in itself. The problem is the gap it appears to open on the inside. The questions are what was signalled, when, and whether the driver checked that space before closing it. Make sure the report does not describe it as a simple sideswipe.

Is there camera footage, and how do I get it?

Very often yes, since many fleets now run forward and side-facing cameras. The difficulty is that footage is normally held on a loop measured in days and is overwritten in the ordinary course of business. A written request that it be downloaded and preserved should go to the carrier as soon as it is identified. Nearby junction, transit or shop cameras are worth chasing too, and those belong to nobody involved.

I was on a bicycle or a motorcycle. Does that change things?

The legal framework is the same and the practical exposure is worse. A rider can sit entirely inside the space alongside a long vehicle, and the consequences of contact are far more serious. Expect the blame argument to be pressed harder, and expect assumptions about riding position to be offered as though they were rules. They are usually neither, and they are worth contesting rather than accepting.

What if I really was there for a while?

Then say so accurately and let it be argued, but understand that it cuts both ways. A vehicle that was alongside for several seconds was available to be seen for several seconds, in mirrors the driver is required to check before moving. Time spent in the space is not automatically a point against you; depending on the facts it can be the strongest thing in your favor.

Will being partly at fault end my claim?

In most states, no. The usual approach is to divide responsibility and reduce the award to match, so a share of blame reduces what you recover rather than removing it. A number of states bar recovery once a claimant's share crosses a stated proportion, and a small minority are stricter still. Because the difference is decided entirely by where the crash happened, this is a question for an attorney licensed there.

The police report blames me. Is that the end?

No. A report records an officer's view formed quickly, often from a single account given at the roadside, and it is not a finding that binds anyone. Reports in these cases frequently misdescribe the maneuver itself, which shapes everything that follows. Footage, vehicle data and the damage geometry on both vehicles routinely tell a different story, and none of that is usually available when the report is written.

How quickly do I need to act?

Quickly, and for reasons that have nothing to do with the legal deadline. Camera loops overwrite within days, vehicles are repaired within weeks, and your own precise memory of the geometry fades faster than you would expect. Writing down where you were and how long you had been there, on the first day, costs nothing and is frequently worth more later than anything else you do.

Do I have to pay anything up front?

Injury firms generally work on a contingency basis, meaning the fee is a percentage of what is recovered set out in the written agreement and there is nothing to pay up front. Case costs, meaning experts and records and filing fees, are a separate item from the fee, and the agreement should say plainly who carries them and what happens to them if the case does not succeed.

Is what I tell you private?

Yes. What you share in a case review is kept private and is used only to match you with an attorney who fits your situation. One distinction is worth understanding: true legal confidentiality, called attorney-client privilege, only attaches once you actually have an attorney-client relationship with a lawyer. Submitting a form to a referral service is not the same thing. If that matters to you, raise it directly with the attorney.

What does it cost to use MVA Lawyer Network?

Nothing. We are a free, independent referral service, not a law firm, and we do not give legal advice. Requesting a case review costs you nothing and puts you under no obligation. When a situation fits, we connect you with an independent attorney who reviews it directly, and we may be paid a referral fee by that attorney. That fee does not add anything on top of their percentage.

Could not see you is not the same as could not have seen you.

One short, private form. No cost, no obligation, and no fee unless there is a recovery.
