If you drive a commercial truck on I-35 through Austin, you already know the stretch between Round Rock and Buda is unpredictable on a good day. Cars merge without checking mirrors. Drivers brake hard to catch exits. At highway speeds, any of those moves near a loaded semi can end badly — and when it does, the question of who pays for it gets complicated fast.

This is not a simple car-versus-car situation. Commercial truck accidents pull in multiple layers of liability, federal regulations, and insurance coverage that most drivers never think about until they’re standing at a crash scene. At Kelley Wolff Injury Attorneys | Austin Accident Lawyers, we handle these cases regularly for clients across Austin and throughout Texas. What follows is a practical breakdown of how liability actually works when another driver cuts off your truck — and what you need to do to protect yourself.

Who Legally Bears Fault When a Car Cuts Off a Semi on I-35?

Texas follows a modified comparative fault system under Texas Civil Practice and Remedies Code §33.001. That means each party in an accident can be assigned a percentage of fault, and you can only recover damages if your share of fault is below 51%. If you’re found 20% at fault, your recovery is reduced by 20%. If you’re found 51% or more at fault, you recover nothing.

Here’s where it gets tricky for commercial truck drivers: even when another driver clearly cut you off, opposing counsel or insurers will look hard for any reason to assign you partial fault. Were you following too close? Were your brakes properly maintained? Did your driving logs show you’d been on the road longer than federal hours-of-service rules allow? Under Federal Motor Carrier Safety Administration (FMCSA) regulations, commercial truck operators are held to a higher standard than regular drivers. That standard cuts both ways — it means your conduct gets scrutinized even when someone else started the crash.

That said, a driver who makes an unsafe lane change and causes a collision can absolutely be held primarily liable. Texas Transportation Code §545.060 requires drivers to stay in their lane unless a lane change can be made safely. If a car darted in front of your truck without adequate clearance and your dashcam or witnesses can confirm it, you have a strong factual foundation for a claim.

The practical advice: do not admit fault at the scene, document everything you can, and speak with a truck driver accident attorney before giving recorded statements to any insurance company.

Can Your Trucking Company or Employer Also Be Named in the Claim?

This question surprises a lot of drivers. Yes — under the legal doctrine of respondeat superior, an employer can be held liable for the negligent acts of an employee who was acting within the scope of employment at the time of the crash. If you were driving your route when the accident happened, your motor carrier may share liability exposure alongside the driver who cut you off.

But the exposure doesn’t stop there. If the investigation uncovers that the trucking company pressured drivers to skip required rest periods, failed to maintain the vehicle, or hired a driver with a problematic safety record, those facts open additional claims against the company directly. The Bureau of Labor Statistics consistently reports that trucking has one of the higher injury rates of any occupation — and regulators know that company policies and equipment maintenance are often contributing factors.

This matters for your claim because the motor carrier typically carries much larger insurance policies than an individual driver. In Texas, the FMCSA requires interstate commercial carriers to carry a minimum of $750,000 in liability coverage for general freight, with higher minimums for hazardous materials. Identifying all potentially liable parties — not just the driver who cut you off — is one of the most important steps in building a truck driver accident claim.

What Evidence Makes or Breaks a Truck Driver Accident Claim in Austin?

Evidence is everything. The good news is that commercial trucks generate more documentable data than almost any other vehicle on the road. The challenge is that some of that evidence disappears fast if you don’t act to preserve it.

The first priority after a crash is the electronic logging device (ELD). Under FMCSA rules that took effect in 2017 and remain in force in 2026, most commercial trucks must use ELDs to record hours of service, GPS location, and engine data. That data can confirm where your truck was, how fast it was traveling, and whether any hard braking event was recorded — which directly supports your account of being cut off.

Dashcam footage is equally critical. If your truck has a forward-facing or cab-facing camera, that footage needs to be preserved immediately. Most systems record in loops, overwriting older footage. Request that the footage be downloaded and preserved within 24 hours of the accident if at all possible.

Other evidence worth gathering: witness statements from other drivers or bystanders, photos of final vehicle positions and road markings, the other driver’s cellphone records (which can be subpoenaed to show distracted driving), and any surveillance cameras mounted on nearby businesses or highway infrastructure. TxDOT operates traffic monitoring cameras on significant portions of I-35 through the Austin metro — those feeds may have captured the cut-off event.

A qualified Austin Motor Vehicle Accident Attorney can send preservation letters to relevant parties before evidence is destroyed or lost.

How Does Fault Split Between Multiple Parties Affect Your Truck Driver Accident Claim?

Real-world crashes on I-35 rarely involve just two vehicles and one clean line of fault. You might have a situation where a car cut off your truck, you braked hard to avoid it, and a second car rear-ended your trailer because it was following too close. Now you have three vehicles, three insurance companies, and potentially three sets of lawyers all trying to push fault onto someone else.

Texas’s comparative fault system handles multi-party crashes by asking the jury (or the parties in settlement) to allocate percentages of fault to every responsible party. Under Texas Civil Practice and Remedies Code §33.013, each defendant is generally only responsible for their own percentage of fault — called proportionate liability — unless they’re found jointly and severally liable under specific circumstances (such as when a party is more than 50% at fault).

For injured parties filing a truck driver accident claim, this means the total recovery can come from multiple sources but is capped by the total fault allocation. If you are the truck driver who was injured in the crash — say, due to a jackknife or rollover caused by the cut-off — you would file claims against the at-fault driver’s liability insurer, and potentially against your own motor carrier’s coverage depending on the circumstances.

FindLaw’s overview of Texas personal injury law is a reasonable starting point for understanding these mechanics, but the specific application to commercial trucking cases requires someone who knows how FMCSA regulations intersect with state tort law.

What Should a Commercial Truck Driver Do Immediately After a Crash on I-35?

The steps you take in the first hour after a crash on I-35 directly affect the outcome of any claim. Here’s what matters most.

Call 911 and stay at the scene. Texas law requires drivers involved in accidents causing injury or significant property damage to remain. A police report documenting the other driver’s lane change is valuable evidence. When officers arrive, give an accurate account of what happened — that the other driver cut in front of you — but do not speculate about speed or other details you’re not certain of.

Seek medical attention even if you feel fine. The physical stress of managing a near-miss or impact in a commercial truck can mask injuries temporarily. The CDC and Mayo Clinic both document that adrenaline following traumatic events can delay pain perception by hours or even days. Conditions like spinal compression, soft tissue injuries, and traumatic brain injury may not present obvious symptoms immediately. Getting evaluated creates a medical record that ties your injuries to the accident date — critical for any personal injury claim.

Notify your motor carrier as required by your employment agreement, but be careful about what you say beyond the basic facts. Contact a truck driver accident attorney before giving a full recorded statement to any insurance adjuster — yours or the other driver’s. Adjusters are trained to gather information that reduces the insurer’s payout, and commercial cases involve significant money.

Justia’s legal resources provide general guidance on accident reporting obligations, but for anything specific to your situation, speak with a licensed attorney.
