Texas is home to some of the busiest highways in the country. From the traffic jams of Houston to the long rural stretches of West Texas, our roads can be unpredictable—and sometimes deadly. Knowing which highways have the highest accident rates can help you stay alert and avoid unnecessary risks.

Based on recent crash data, here are the most dangerous roads in Texas, what makes them hazardous, and what you should do if you’re ever hurt in a crash caused by someone else’s negligence.

The Deadliest Highways in Texas

Interstate 10 (I-10)

Stretching 879 miles across the state, I-10 is the deadliest highway in Texas. It averages over 130 fatalities a year, with especially dangerous stretches in Beaumont and West Texas. High speed limits (up to 85 mph), heavy truck traffic, and poor road conditions all add to the risk.

Interstate 45 (I-45)

I-45, running through Houston, is considered one of the deadliest highways in the U.S. It averages around 65 fatalities a year, with Harris County alone seeing dozens of fatal crashes annually. Congestion, high speeds, and severe weather make this route especially dangerous.

Interstate 35 (I-35)

Running straight through San Antonio and Austin, I-35 averages nearly 60 deaths a year. Construction zones, sudden lane changes, and the mix of local and long-haul drivers often lead to multi-car wrecks and rear-end collisions.

Interstate 20 (I-20)

Spanning across North Texas, I-20 averages more than 50 fatalities a year. Long, flat stretches encourage speeding and drowsy driving, while the heavy presence of semi-trucks raises the severity of accidents.

U.S. Route 83 (US-83)

Nicknamed one of the “deadliest highways in America,” US-83 runs from Laredo up to the Panhandle. It averages about 34 fatalities a year, with sharp curves, limited shoulders, and unpredictable weather creating hazards, especially in rural stretches.

U.S. Route 285 (US-285)

Known locally as the “Death Highway,” US-285 runs through the oil fields of West Texas. With heavy truck traffic, high speeds, and poor infrastructure, crashes have surged in recent years.

U.S. Highway 59 (US-59)

Around Houston, US-59 sees high crash rates due to merging traffic, commercial trucks, and speeds up to 75 mph. The combination of congestion and high impact collisions makes this road especially risky.

Why These Roads Are So Dangerous

The main causes of deadly crashes in Texas include:

• Speeding – Contributes to nearly one-third of fatal accidents statewide.
• Drunk Driving – Involved in about 1 out of every 4 fatal wrecks.
• Distracted Driving – Texting, fatigue, or inattention causes almost 10% of deadly crashes.
• Rural Risks – Poor lighting, wildlife crossings (like deer or hogs), and limited emergency response make rural accidents especially deadly.

In cities like Houston and San Antonio, congestion and reckless lane changes add another layer of danger, particularly at night.

What to Do If You’re Injured in a Crash

If you’ve been hurt in an accident on one of these roads, here’s what to do:

1. Call 911 and get an official crash report.
2. Get medical care right away, even if injuries seem minor.
3. Take photos of the scene, vehicles, and road conditions.
4. Get witness information if anyone saw the crash.
