If you think San Antonio traffic is bad, well, you're correct. But it's worse in Houston and Dallas.

If you’re white-knuckling your daily commute, it may be for good reason.

Some of Texas’ highways run straight through the heart of San Antonio, making it among the state’s deadliest cities for drivers, according to a new study commissioned by Houston-based injury lawyer Brian White.

Researchers used 2024 data from the National Highway Traffic Safety Administration (NHTSA) to analyze which Texas roadways had the highest number of recorded deaths from automobile accidents.

Topping the list is the stretch of I-35 that runs from Laredo to the Red River, including, of course, the portion that passes through San Antonio.

The portion of I-35 passing through Texas recorded 167 deaths from 142 car crashes in 2024.

The second-deadliest was the stretch of I-10 that runs through the Lone Star State, including San Antonio. A total of 138 deaths were recorded in 2024 along that segment of the interstate.

U.S. Highway 90, which connects San Antonio to Houston, also made the list at No. 7. That stretch of road recorded 54 deaths.

Even so, California has deadlier roads than Texas overall, but just barely, according to a recent analysis by life insurance website PolicyGenius.
