How is a Highway Accident in Texas Different From a City Accident?

You were holding 70 in the right lane on I-35 when traffic stopped ahead, and the pickup behind you did not. The same Texas rules of the road apply to both highway and city crashes. What changes is the number attached to those rules, the energy behind the impact, and how many insurers end up in the file. A highway accident in Texas is often harder to resolve than a city collision, even when fault is obvious.

Same Texas Traffic Laws, Very Different Numbers

Chapter 545 of the Texas Transportation Code applies to drivers on both interstates and city streets. Applicable speed limits and safe-driving requirements depend on the road type and surrounding conditions.

Under Tex. Transp. Code § 545.352, the prima facie speed limit is 30 mph in an urban district and 70 mph on a state or federally numbered highway outside an urban district. The limit is 60 mph on a non-numbered highway outside an urban district. Exceeding these limits may be used as evidence that the driver’s speed was unreasonable and unlawful.

§ 545.353 allows the Texas Transportation Commission to post a 75 mph limit when it finds that speed reasonable and safe. It also allows 80 mph on certain parts of I-10 and I-20 and up to 85 mph on roads designed to accommodate that speed.

Driving at or below the posted limit does not always mean the speed was safe. § 545.351 requires drivers to use a reasonable and prudent speed for the existing conditions. Drivers may need to slow down around curves, on hill crests, on narrow roads, in traffic, or in hazardous weather.

Other driving duties apply on both highways and city streets. § 545.060 requires drivers to stay as close as practicable within a single lane and change lanes only when safe. § 545.062 requires an assured clear distance that accounts for speed, traffic, and road conditions, with added spacing for trucks outside business or residential districts.

Why the Same Mistake Causes Catastrophic Injury at Highway Speed

The difference comes down to crash energy. According to the Insurance Institute for Highway Safety, increasing impact speed from 40 to 60 mph raises crash energy by 125 percent, even though speed increases by only 50 percent. Vehicle structures, restraints, and roadway barriers can only absorb so much of that additional force.

Speed also increases the time between seeing a hazard and reacting, lengthens stopping distance once braking begins, and raises the chance that a hard steering correction leads to a loss of control.

TxDOT’s preliminary 2025 records show that Interstates accounted for 671 traffic deaths and US and State highways for 1,374. Another 50 deaths occurred on tollways, compared with 818 on city streets out of 3,769 statewide. These statewide totals include substantial differences among individual counties, as reflected in Texas crash data by county and road type.

The same driving error can cause much more severe injuries on I-30 than on a lower-speed city street. When an interstate crash is fatal, the family may be able to bring a wrongful death claim.

How Highway Crashes Affect Insurance Claims

A highway claim is harder to resolve because the money and the fault are both divided in more ways.

Tex. Transp. Code § 601.072 sets Texas minimum liability coverage at $30,000 for bodily injury to or death of one person, $60,000 for two or more people in one collision, and $25,000 for property damage. A serious highway crash can result in damages that exceed these minimum limits.

Texas may divide responsibility among several parties. Under Tex. Civ. Prac. and Rem. Code § 33.013, a liable defendant generally pays the percentage of damages equal to their percentage of responsibility. A defendant may be jointly and severally liable when their responsibility exceeds 50 percent or in certain intentional-conduct cases.

A chain-reaction crash may involve several responsible drivers and several insurance companies. Identifying only one driver could exclude other potentially available coverage from the claim.

Your own policy may provide another source of coverage. Tex. Ins. Code § 1952.101 requires Texas insurers to offer uninsured or underinsured motorist coverage unless the named insured rejects it in writing.

Under Brainard v. Trinity Universal Insurance Co. (Tex. 2006), a UIM insurer does not have to pay benefits until the insured obtains a judgment establishing the other driver’s liability and underinsured status.

Why Highway Cases Need Reconstruction, & Why the Evidence Window Is Short

Highway crashes can leave vehicles far from the original point of impact. A vehicle in a chain reaction may also be struck more than once, making it difficult to determine the order of events from photographs and damage patterns alone.

Event data may help reconstruct what happened. Under 49 CFR Part 563, covered vehicles equipped with an event data recorder may capture pre-crash speed, changes in velocity, throttle percentage, brake and safety belt status, and airbag deployment timing.

Not every vehicle has a recorder, and obtaining another driver’s data may require additional steps. Tex. Transp. Code § 547.615 generally makes recorded data the vehicle owner’s property. Other parties may need the owner’s consent or a court order to access it.

§ 550.062 requires an officer’s written report when a crash causes injury, death, or apparent property damage of $1,000 or more to any one person’s property, to be filed electronically no later than the 10th day after the collision. Getting your Texas crash report only takes a few steps.

Tire marks, gouges, fluid trails, and debris can also help establish how the crash happened. Traffic and weather may disturb that evidence, so document the scene as early as possible.

What to Do After a Highway Accident in Texas

The basic steps to take after a car accident also apply to a highway crash. However, you may need to document and preserve evidence on a busy roadway quickly.

1. Get a medical evaluation, even if you feel functional. High-energy injuries don’t always show up at the scene.
2. Document the roadway while conditions are unchanged. Photograph pavement marks, debris, and vehicle positions before the scene is cleared.
3. Confirm the crash report exists and request it. § 550.062 sets a ten-day electronic filing deadline.
4. Identify every vehicle, driver, and carrier. Under § 33.013, a missed defendant can mean missed recovery.
5. Check your own policy for UM/UIM coverage. Under § 1952.101, you likely have it unless you rejected it in writing.
6. Get preservation demands out early. Non-deployment recorder data can be overwritten, and the six-month floor under 49 CFR 395.8(k) is already running.
