The most dangerous roads for truck accidents in San Antonio are the freight-heavy interstates and their interchanges, especially I-35, Loop 410, I-10 and the downtown Mixing Bowl, along with Loop 1604 work zones and busy commercial arterials like Culebra Road and Bandera Road. These are the places where heavy trucks and commuter traffic share tight space at changing speeds.
The numbers are moving in the wrong direction. TxDOT reported 2,684 crashes involving commercial motor vehicles in Bexar County in 2024, up from 2,460 in 2023.
Where a crash happens shapes the case that follows: which agency writes the report, which cameras may have recorded it, and which court hears the lawsuit. The trucking company’s investigators know this and start working the scene right away.
This guide covers the high-risk corridors, why trucks crash on them, what the local crash data shows, and how the location of your wreck affects your claim. Call 210-TREVINO for a free case review.

Which San Antonio Roads Have the Most Truck Crashes?
Truck crashes cluster where long-haul freight and local traffic meet: the interstate corridors, the interchanges that connect them, and the commercial streets that feed warehouses and stores. Each corridor carries a different kind of risk.
I-35, Loop 410 and the Downtown Mixing Bowl
I-35 is the main north-south freight route through San Antonio, carrying trucks between the Laredo border crossings and the rest of the country. Where it meets Loop 410 and, west of downtown, I-10 and US 90 at the interchange locals call the Mixing Bowl, trucks have to change lanes and merge across short distances while commuters do the same. Rear-end crashes, sideswipes and blind-spot merges are common patterns.
I-10
I-10 crosses the city east to west and carries long-haul trucks through the urban core and out toward the Hill Country. Long stretches at highway speed raise the stakes of driver fatigue and following too closely, which federal hours-of-service rules are meant to prevent.
Loop 1604 Construction Zones
Expansion work on Loop 1604 brings lane shifts, concrete barriers, narrowed lanes and sudden slowdowns. A loaded truck needs far more room to stop than a car, so a driver who does not slow down for the work zone can overrun the traffic ahead or clip a barrier and lose control.
Culebra Road, Bandera Road and Other Commercial Arterials
On the Northwest Side, Culebra Road and Bandera Road carry delivery vans, box trucks and freight trucks serving retail and distribution sites. Wide right turns, center turn lanes and crowded intersections create side-impact and turning crashes, often at lower speeds but with serious injuries.
Where Do Truck Rollovers Happen Most in San Antonio?
Rollovers tend to happen on curved connector ramps and interchange loops, where a truck that enters too fast or with a shifting load cannot hold the curve. A tall trailer has a high center of gravity, so speed that is safe for a car can tip a loaded truck.
- Tight connector ramps between I-35, I-10 and Loop 410, where the curve tightens near the end of the ramp
- Work zones on Loop 1604 and other projects, where lane shifts force quick steering corrections
- Local roads and turns, where box and delivery trucks take corners too fast
- Load problems, such as unsecured or poorly balanced cargo that shifts in a curve
In a rollover case, the investigation looks at speed going into the curve, the truck’s electronic data and how the cargo was loaded and secured. Our San Antonio truck rollover accident lawyers handle these claims, including when a shipper or loading company shares the blame.
What Does the Crash Data Show for Bexar County?
TxDOT’s county crash reports show commercial vehicle crashes in Bexar County rising from 2023 to 2024, with more deaths and more serious injuries.
| Bexar County, CMV-involved crashes | 2023 | 2024 |
|---|---|---|
| Total crashes | 2,460 | 2,684 |
| Fatal crashes | 13 | 18 |
| Fatalities | 14 | 18 |

These county totals do not break crashes down by road, so the crash report for your own wreck, together with the scene evidence, is what shows how and where it happened.
How Does the Crash Location Affect Your Truck Accident Claim?
The location decides who investigates, what evidence exists, which court hears the case and, in some cases, whether a road defect can be part of the claim.
Which Agency Writes the Crash Report?
A crash inside city limits is usually worked by the San Antonio Police Department, while crashes elsewhere in the county may be handled by the Bexar County Sheriff’s Office or the Texas Department of Public Safety. Knowing which agency responded tells us where to request the report, photos and any officer video.
What Evidence Depends on the Location?
Traffic cameras, nearby business cameras, skid marks and debris are all tied to the scene, and much of it is recorded over or cleaned up quickly. The truck’s electronic control module and driver logs travel with the company. We send a spoliation letter to protect the truck’s black box data and follow the steps for preserving evidence after a truck accident as early as possible.
Where Will the Lawsuit Be Filed?
Texas venue rules generally allow a lawsuit in the county where all or a substantial part of the events happened, so a crash on a San Antonio highway is usually filed in Bexar County. A trucking company may try to move the case, and how a court rules on that can affect strategy.
Can You Sue the State for a Dangerous Road?
Usually not for the road’s design. In State v. Rodriguez, 985 S.W.2d 83 (Tex. 1999), a truck driver was killed when his rig failed to make a sharp turn on a highway detour and rolled over. The Texas Supreme Court held that the State kept its immunity because designing the detour and placing its warning signs were discretionary decisions, and the detour was not a special defect. Claims against the State for road conditions are narrow, which is why the focus usually stays on the truck driver, the trucking company and anyone who loaded or maintained the truck.
Dangerous Truck Roads in San Antonio: Quick Answers
What Is the Most Dangerous Highway for Trucks in San Antonio?
I-35 and its interchanges with Loop 410 and I-10 carry the heaviest freight traffic through the city, which makes them a frequent setting for serious truck crashes. TxDOT’s county figures do not rank individual roads, so each crash is judged on its own report and evidence.
Does Road Construction Change Who Is at Fault?
Not by itself. Truck drivers must adjust their speed and following distance for work zones. A driver or trucking company that ignores lane shifts and reduced speeds can be held responsible even though construction made the road harder to drive.
How Long Do You Have to File a Truck Accident Lawsuit in Texas?
In most cases, two years from the date of the crash. Some claims have shorter deadlines or special notice rules, so talk to a lawyer early. Your deadline and the evidence both affect what a truck accident settlement can be worth.
