How to Safely Share the Road With 18-Wheelers in Texas
Texas has some of the busiest freight corridors in the country, I-35, I-45, and I-10 all carry heavy truck traffic day and night. Sharing the road with 18-wheelers is routine for most Texas drivers, but a lot of people misjudge how differently big rigs handle compared to a passenger car, and that gap in understanding is where most close calls happen.
Know Where Their Blind Spots Actually Are
Truck drivers call them "No-Zones," and they're bigger than most people expect: directly behind the trailer, a long stretch alongside both sides of the cab, and a wide area directly in front of the truck. A simple rule covers most of it, if you can't see the truck driver's face in their side mirror, they very likely can't see you either.
Give Them Room to Maneuver
- Never cut in front of a truck and brake. Stopping distances for loaded trucks are far longer than for a car.
- Pass on the left when possible, it's the side with the smaller blind spot, and pass decisively rather than lingering alongside.
- Give trucks extra room on turns, their trailers swing wide and may need more of the lane, or an adjacent one, to complete the turn.
- Avoid tailgating a truck. You lose your view of the road ahead, and you sit in one of their blind spots the entire time.
Watch for Wind and Wake Turbulence
Passing a semi at highway speed, especially in high wind, can pull your car slightly toward the truck as you enter its slipstream, then push you away as you exit it. Keep a firm, steady grip on the wheel through the pass and expect the brief tug in both directions.
Plan Ahead on Long Hauls
Truck traffic is heaviest on long interstate stretches, exactly where fatigue and inattention are also most likely to creep in. Staying alert, scanning well ahead, and keeping steady following distance are core habits taught in our driving safety courses across Texas, and they matter most on the highways where trucks make up a large share of the traffic around you.
