Share on social:

If you live in San Antonio or travel regularly between San Antonio and Austin, chances are you know Interstate 35 all too well. It’s one of the most heavily traveled highways in Texas and, unfortunately, one of the most dangerous. Serious car crashes, catastrophic truck accidents, and fatal collisions happen on I‑35 with alarming frequency, particularly in the stretch running through San Antonio and north toward New Braunfels. 

Many saw the January 2026 viral video of a pickup truck running off the road and crashing into an overhead highway sign near New Braunfels.  This case is somewhat fortunate to involve only one vehicle. Many others aren’t as lucky, sweeping up other innocent motorists. 

At Crosley Law, we’ve handled many cases involving I‑35 accidents. We’ve seen firsthand how devastating these wrecks can be and how complex the legal issues often become. Understanding why I‑35 is so dangerous can help you stay more alert on the road. And if you’ve already been injured, it can also help you understand why your case deserves serious attention. 

Here are some of the major reasons why accidents happen so often on I‑35, the unique risks posed by commercial trucks, and how the experienced San Antonio car accident lawyers at Crosley Law can help if you or a loved one has been hurt.

I‑35 generates a storm of risk factors for car accidents 

Reports consider I-35 one of the most dangerous roads in Texas because multiple high‑risk factors can collide at once for travelers. 

Heavy traffic volume from multiple regions 

While I‑35 around San Antonio may serve as a local highway for many around here, it’s a major north‑south corridor that connects many areas including: 

  • Laredo and the U.S.–Mexico border 
  • San Antonio 
  • New Braunfels 
  • Austin 
  • Dallas–Fort Worth 

This means I‑35 often carries a mix of local commuters, tourists, long-haul commercial truck drivers, and delivery vehicles. Many of those drivers can also come from out-of-state and may not be as familiar with I-35 accident risks as the locals. 

The sheer volume of traffic dramatically increases the risk of crashes, especially during rush hour, holidays, and weekends. 

Congestion and sudden stop‑and‑go traffic 

One of the most dangerous features of I‑35 around San Antonio is how quickly traffic conditions can change. You might be moving at highway speeds one moment, then suddenly come to a near standstill the next. This is especially common: 

  • Near downtown San Antonio 
  • Around major interchanges 
  • In construction zones (of which there can be many) 
  • Northbound toward New Braunfels during peak hours 

Sudden slowdowns can lead to rear‑end collisions, chain‑reaction crashes, and multi‑vehicle pileups. These crashes often cause serious injuries, including spinal injuries and traumatic brain injuries, even when vehicles don’t appear heavily damaged. 

Construction zones and lane shifts 

I‑35 seems perpetually under construction, and for good reason. Its aging infrastructure is carrying far more traffic than it was originally designed to handle. 

Construction zones introduce several dangers: 

  • Narrow lanes 
  • Confusing lane shifts 
  • Reduced shoulders 
  • Poor visibility 
  • Distracted or impatient drivers 

In these zones, even a small mistake can have devastating consequences. Crashes in construction areas often involve multiple vehicles and can raise complicated legal questions about liability, including whether contractors, trucking companies, or government entities played a role in a crash. 

Speed differentials between vehicles 

On I‑35, you’ll often see a wide range of speeds: 

  • Drivers traveling well above the limit 
  • Commercial trucks moving more slowly due to weight and regulations 
  • Congested lanes next to free‑flowing traffic 

These speed differences make lane changes especially dangerous. A driver who misjudges the speed of an approaching vehicle—or a truck driver who can’t stop in time—can cause a catastrophic crash. 

Commercial truck accidents on I‑35 

Some of the most serious and deadly accidents on I‑35 involve commercial vehicles. 

Why are trucks so common on I‑35? 

I‑35 is a critical freight corridor. It’s heavily used by: 

  • 18‑wheelers 
  • Cross‑border freight carriers 
  • Construction and industrial vehicles 

These trucks are larger, heavier, and far more dangerous in a crash than passenger vehicles.

Common causes of truck accidents on I‑35 

Truck accidents along I‑35 often stem from issues such as: 

  • Distracted driving 
  • Speeding to meet delivery deadlines 
  • Improper lane changes 
  • Mechanical failures 
  • Overloaded or improperly secured cargo 

Because trucks require longer stopping distances, congestion and sudden slowdowns on I‑35 are especially hazardous.

Why truck accident cases are often more complex 

Unlike standard car accident claims, truck accident cases often involve: 

  • Multiple defendants (driver, trucking company, maintenance contractors) 
  • Federal trucking regulations 
  • Electronic data from the truck (black box, ELDs, GPS) 
  • Aggressive insurance defense teams 

These cases require immediate investigation and an attorney who understands both Texas personal injury law and federal trucking regulations.

What happens after an I‑35 accident? 

If you’ve been injured in a crash on I‑35, you may be facing: 

  • Serious injuries 
  • Mounting medical bills 
  • Lost income 
  • Insurance companies disputing fault 
  • Pressure to settle quickly 

Insurance companies know that I‑35 crashes are common. They will often try to minimize payouts by shifting blame, downplaying injuries, or arguing that congestion or “traffic conditions” were unavoidable. 

This is where having an experienced San Antonio car accident lawyer can help.
