When it comes to traffic safety, San Antonio is in the danger zone.

An analysis of 2018 data from the U.S. Census Bureau and Texas Department of Transportation published by Austin-based Aceable, a provider of online driving courses, puts San Antonio at No. 11 among the 20 most dangerous cities for drivers.

Aceable ranked the 40 largest Texas cities based on the number of fatal traffic accidents per 100,000 residents. San Antonio recorded 8.81 fatal traffic accidents per 100,000 residents, according to the study.

“From distracted driving to drunk and drugged driving to drowsy driving to outdated laws and infrastructure, there are many factors that play a role in road safety — and the reality is most accidents are actually largely preventable,” Laura Adams, driving safety and education analyst at Aceable, says in a February 19 release. “We hope this report encourages drivers, local leaders, and legislators across the state to take action to make the roads safer.”

The most dangerous city for Texas drivers is Dallas, with 14.42 fatal traffic accidents per 100,000 residents. Other Texas cities on the most-dangerous list include Houston, tied with Abilene for No. 14, with 8.13 fatal accidents per 100,000 residents, and Austin, No. 18 with 6.84 fatal accidents per 100,000 residents.

The two safest big cities in Texas are Allen and The Woodlands, which both recorded zero fatal traffic accidents. Waco ranks the 15th safest (5.79 fatal traffic accidents per 100,000 residents), followed by Killeen, 16th, with 6.04 fatalities per 100,000 residents.
