Blind Spot Truck Accident Lawyer in Louisiana: Proving Liability When You Were in the “No-Zone”

An 18-wheeler changed lanes or turned into you, and now you are being told it was your fault for being in the driver’s blind spot. That one sentence from an adjuster ends a lot of claims before anyone looks at the truck. It should not end your claim without a closer look.

A blind spot truck accident lawyer starts somewhere else: with what the driver was required to do before you entered the blind spot and/or moved that truck.

The Ikerd Law Firm handles Louisiana 18-wheeler wreck cases across Louisiana and Texas. You can contact our Lafayette office or call (337) 366-8994.

Key Takeaways

• Being in a truck blind spot does not, on its own, decide who is responsible for the crash.
• Federal rules require mirrors on both sides of a commercial truck, require the driver to be satisfied that those mirrors work before driving, and require the driver to use them when and as needed on the road. Driver training must cover visual search and the proper use of mirrors.
• Under the version of Louisiana’s comparative fault article in force since January 1, 2026, recovery is barred when your share of the negligence reaches 51 percent.
• Below that share, damages are reduced in proportion to your percentage of fault rather than erased.
• The trucking company, not you, keeps the records that show whether the driver looked.

Why Truck Blind Spots Are Called the No-Zone

The no-zone is the space around a large truck where the driver may not be able to see you. The Federal Motor Carrier Safety Administration puts it plainly in its road safety guidance for drivers: if you cannot see the face of a truck or bus driver in your mirror, that driver cannot see you.

Those areas sit on all four sides of a tractor-trailer. Where each one falls depends on the truck, the trailer, and how the mirrors are set.

Learning where truck blind spots sit is useful, and the phrase “semi truck no zone” is worth knowing for the same reason. Neither one decides who is at fault in your crash. We cover where these crashes happen in our guide to I-10 and I-49 corridor truck crashes in Louisiana.

Two other things about large trucks show up in the same crashes, and the same FMCSA guidance names both of them. Trucks and buses “need the length of up to two football fields to safely stop,” and they “need extra space and time to make wide turns carefully.”

That matters when a company blames the no-zone for a right-turn crash. FMCSA tells drivers to expect wide turns, noting that trucks and buses “may not be able to easily turn from the right lane and may initially move left to create enough turning space.” A truck that swings left before turning right is doing what FMCSA describes, and your position relative to the trailer is only part of the picture.

What the Driver Was Required to Do Before Moving the Truck

No driver can see every inch around a tractor-trailer, and federal rules account for that. They set what the truck must carry, and the training curriculum sets what the driver has to be taught.

• Mirrors on both sides. 49 C.F.R. § 393.80 requires every truck and truck tractor to carry two rearview 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.”
• Training on visual search. The Class A CDL curriculum at Appendix A to Part 380 includes a unit that “must teach driver-trainees to visually search the road for potential hazards and critical objects,” and a later unit in which trainees “must demonstrate proficiency in the proper techniques for visually searching the road.”
• Training on mirrors themselves. The same curriculum requires instruction on “the proper use of vehicle safety components, including safety belts and mirrors.”
• Mirrors checked as equipment. 49 C.F.R. § 396.11 lists rear vision mirrors among the parts a driver’s end-of-day report must cover, and that report lists any defect or deficiency that would affect safe operation. The rule also states that drivers “are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver.”

None of that makes a trucking company automatically responsible for a blind spot crash. It does widen the question beyond where your vehicle was to what the driver did with the mirrors and the training the job required.

When the Trucking Company Says You Were in the Blind Spot

Here is the argument you are up against. The company says you put yourself somewhere its driver could not see, so the crash is on you.

An attorney who focuses on 18-Wheeler wreck cases and trains in this area of law knows how to counter this argument. The simple answer is that there should almost never be a “blind” spot. Unless the smaller vehicle is driving recklessly and excessively speeding up to the tractor-trailer, no vehicle should ever enter the “no-zone” without the truck driver’s knowledge.

CDL drivers are trained on and responsible for checking their mirrors and surroundings every three seconds. Thus, if a vehicle is in an area the mirrors cannot see during a lane change, the driver should have clocked it minutes earlier when it drove up next to the 18-wheeler. The CDL driver should never be surprised by someone being next to them.

Louisiana responds with a comparative fault system instead of an all-or-nothing rule. Under Article 2323 of the Louisiana Civil Code, a court assigns a percentage of fault to everyone who caused or contributed to the injury.

What that percentage does to a claim changed recently, and the change matters:

• At 51 percent or more of the negligence, the injured person “shall not be entitled to recover damages.”
• Below 51 percent, the damages “shall be reduced in proportion to the degree or percentage of negligence” of the injured person.
• The amendment is Act 2025, No. 15, effective January 1, 2026. Which version applies to a particular crash depends on its date, and that is a question for an attorney, not a web page.

So partial fault is not automatically the end of a Louisiana claim. Where your share of fault falls is a factual question, and the driver’s conduct is part of that same question. That is why Louisiana comparative fault law and the driver’s own duties get argued together rather than separately.

Expect the argument to run in both directions. The company points to where your vehicle sat before the collision. Your side points to the mirrors, the training, and what the truck’s own records show about the seconds before impact.

Neither side sets your percentage. Article 2323 says the degree of fault is determined for everyone who caused or contributed to the loss, “regardless of whether the person is a party to the action or a nonparty.”

Fault in Louisiana starts with Article 2315, which states that “every act whatever of man that causes damage to another obliges him by whose fault it happened to repair it.”

The Records That Show Whether the Driver Looked

The answer to who is at fault in a blind spot accident sits in records you have never seen. Several are the carrier’s own records, and federal rules say what those must contain. Others come from the truck and from the scene.

1. Inspection reports. Under 49 C.F.R. § 396.11, rear vision mirrors sit alongside brakes, steering, and tires on the list a driver’s report must cover when a defect or deficiency is found or reported.
2. The driver qualification file. 49 C.F.R. § 391.51 requires a carrier to keep a file for each driver it employs, including the employment application and the driving record from each licensing authority.
3. Training records. The curriculum in Appendix A to Part 380 sets what the driver was supposed to be taught about visual search and mirror use.
4. The driver’s record of duty status. 49 C.F.R. § 395.8 requires a carrier to have each driver record their duty status for each 24-hour period, ordinarily using an electronic logging device. The rule sets out exceptions, including certain short-haul and driveaway-towaway operations and vehicles manufactured before model year 2000.
5. Electronic data from the truck. Onboard systems and cameras can show speed, braking, and signaling in the seconds before impact.
6. The scene itself. Damage patterns, lane position, and the point of contact can speak to where each vehicle was.

Those records are also the reason speed matters after a crash. Some are kept for a limited period, and vehicles get repaired or returned to service.

A written request to preserve them goes out early for that reason. We cover the wider set in our guide to the federal trucking rules in Louisiana truck cases.

If a carrier has already told you that you were in the blind spot, contact our Lafayette office before those records age out.

What to Do If You Were Blamed for Being in a Blind Spot

You were blamed at the scene, and that is the other driver’s account rather than a finding. These steps help you stay flexible while the facts are clarified.

1. Write down what you remember about the truck, including the company name and any numbers on the cab or trailer.
2. Keep every letter, email, and text from the insurer, especially anything describing where your vehicle was.
3. Photograph the damage on both vehicles before repairs begin, if you are able to.
4. Check the time limits. Legal deadlines and procedural requirements may apply, and our guide to the filing deadline for a Louisiana personal injury lawsuit explains them.
5. Read our page on what to do after a Louisiana truck accident for the first steps to take after a crash.
