Texas has more roadway miles than any other state, and with that comes a consistently high number of serious and fatal crashes. In 2024, Texas recorded over 4,150 traffic deaths, many occurring on long-distance routes that become even more hazardous during holiday travel. Heavy truck traffic, unpredictable winter weather, and long rural stretches all contribute to elevated risk.
This report takes a closer look at the most dangerous highways in Texas, based on crash patterns, fatality rates, and real incidents from the past year. Each corridor presents unique challenges that drivers should understand before getting behind the wheel.
I-45 frequently tops national lists of high-risk highways. Running from Galveston through Houston and up to Dallas, it combines dense commuter traffic with high speeds and one of the busiest commercial trucking corridors in the state.
Why the risk is so high:
In December 2024, a multi-vehicle collision involving two semis and several passenger cars shut down lanes near Houston for hours. Poor visibility and speed were cited as contributing factors, a scenario that becomes more common during the colder months.
I-35 stretches from the Mexico border through San Antonio, Austin, Waco, and into Dallas-Fort Worth. It is one of the most heavily traveled corridors in Texas, and congestion is a major contributor to both minor and severe crashes.
Key risk factors:
A late-December 2023 crash in North Austin involving more than ten vehicles resulted in multiple injuries. Wet roads and dense holiday traffic created conditions that reduced reaction time and increased crash severity.
I-10 runs west to east across the state, linking El Paso, San Antonio, and Houston. Its length and speed limits make it one of the most challenging highways for long-distance travelers.
Why I-10 is dangerous:
A fatal head-on collision near Fort Stockton in early 2024 involved a driver who drifted into oncoming lanes. Investigators noted fatigue, a recurring theme on I-10, particularly during extended travel periods.
US-83 spans remote areas of South and West Texas where speeds are high, visibility can be limited, and distances between towns are long. Rural highways often have higher fatality rates because crashes tend to involve higher speeds and longer emergency response times.
The primary dangers include:
A head-on collision near Zapata in November 2024 left two people dead. Lane drift, combined with high speeds, was a major factor, a pattern seen repeatedly on rural corridors.
Known to many as “Death Highway”, US-285 carries a mix of passenger vehicles and heavy commercial traffic, especially near the oilfields. The combination of fatigued drivers, narrow roadways, and overloaded schedules creates a volatile environment.
Notable risk contributors:
A fatal rollover near Pecos in December 2023 was linked to driver fatigue. Long shifts and overnight driving make crashes on US-285 particularly severe.
I-20 connects the Dallas-Fort Worth metroplex to West Texas communities like Abilene, Midland, and Odessa. It carries a significant volume of trucks, and portions of the highway are prone to multi-vehicle collisions.
Contributing factors include:
In early January 2024, a pileup near Weatherford involving more than fifteen vehicles resulted in several serious injuries. Freezing drizzle created black ice that drivers could not see until it was too late.
Looking beyond individual corridors, several statewide trends help explain why certain highways consistently show higher crash and fatality numbers:
Speeding remains a leading cause of fatal crashes in Texas, contributing to more than 1,200 deaths in 2024.
Texas leads the nation in commercial truck registrations. Interstates with oilfield or freight routes see increased severity in collisions.
Long distances and late-night travel contribute to lane drift and head-on collisions.
More than 1,000 fatalities in 2024 involved impaired drivers, a number that rises during holiday periods.
Ice, fog, freezing rain, and low visibility play significant roles in multi-vehicle crashes.
Holiday travel amplifies existing dangers due to:
When combined with already high-risk corridors, these factors significantly increase the likelihood of severe accidents.
Driving on these highways does not have to be unsafe. Some precautions can meaningfully reduce risk:
Check forecasts for ice, fog, or storms, particularly in West Texas, North Texas, and the Hill Country.
Take regular breaks to reduce fatigue-related errors.
Especially when driving near commercial trucks or in construction zones.
Fatal crash severity increases sharply above posted limits.
Visibility decreases, and impairment rates rise after dark.
Texas highways offer both convenience and challenge, especially during the holiday season. Understanding where the highest risks exist, and why, is one of the most effective ways to stay safe on the road. High-traffic interstates like I-45, I-35, and I-10, along with rural routes like US-83 and US-285, require added caution due to their crash histories and unique hazards.
If you or someone you love is involved in a crash, your next steps matter. Understanding your rights under Texas law can help you pursue compensation for medical bills, lost income, and other damages resulting from the accident.
