If you’ve ever been stuck behind a slow driver on a narrow, rural Texas highway, you may have wondered: Is it legal to pass on a two-lane road in Texa, and how can you do it safely?
Two-lane highways are common across Texas, from the winding backroads of the Hill Country to rural roads connecting small towns and major cities. Millions of drivers use these roads every day for work, errands and travel, but limited visibility and oncoming traffic can make passing risky.
Understanding when passing is legal — and when it’s dangerous or prohibited — can help drivers avoid tickets and reduce the risk of serious crashes.
According to Texas Transportation Code § 545.051, drivers are allowed to pass another vehicle on a two-lane highway in Texas—but only when it can be done safely. Before passing, drivers must ensure the oncoming lane is clearly visible and free of approaching traffic. They should then move into the left lane to overtake the vehicle, maintain a safe distance while passing, and return to the right lane only after they have completely cleared the other car.
The Texas Department of Transportation (TxDOT) warns that unsafe passing is a leading cause of head-on crashes, particularly in areas where passing is restricted, such as hills or curves where oncoming traffic is harder to see. Drivers can also be fined up to $200 for impeding traffic in a passing zone.
Texas law also prohibits passing on the right shoulder if it requires leaving the main traveled portion of the roadway.
While passing is legal on many two-lane highways, it comes with added risk because it requires entering the lane of oncoming traffic. Safety concerns have been especially prominent on Texas Highway 46 near San Antonio, where officials in Bandera and Kendall counties have called on TxDOT to improve what they describe as inadequate infrastructure. More than 1,100 people have signed a petition urging safety upgrades along that stretch of road.
Under the same Texas law, drivers being overtaken must stay to the right and allow the passing vehicle to complete the maneuver safely. It is illegal to accelerate or otherwise interfere until the other driver has fully passed.
