Driving With a Trailer
Driving With a Trailer
What Changes Behind the Wheel
Driving a vehicle is a learned skill. Driving with a trailer is a new learned skill — closer to driving a different vehicle entirely than driving your truck with extra weight. Here’s what changes.
Speed and the Texas speed limit myth
A common question: “What’s the speed limit when towing a trailer in Texas?”
For trailers with a gross vehicle weight rating (GVWR) under 26,000 lbs — which covers every trailer in our fleet and almost every consumer rental in Texas — the answer is the posted speed limit, same as a passenger car. There is no separate trailer speed limit in Texas. Drivers sometimes hear “65 when towing” — that’s not the law in Texas. It’s the law in some other states.
That said: just because you can drive 75 doesn’t mean you should. Most experienced tow drivers cruise 5–10 mph below the posted limit when loaded. Wind, sway, and braking distance all get worse the faster you go.
Acceleration
Everything takes longer. Pulling out from a stop, merging onto I-35, passing a slow vehicle on US-290 — you need more space and more time. Watch how much road is ahead of you before you commit, not after.
Braking distance
A loaded trailer roughly doubles your stopping distance. If you usually leave one car-length per 10 mph in traffic, leave two. On the highway, leave at least 5 seconds of following distance, more in rain.
Practical rule: brake earlier and lighter. Slamming brakes with a loaded trailer can break the load free, cause sway, or jackknife the rig. Trail brake — squeeze gently, hold, release — instead of stabbing.
Turning
Trailers track inside your truck’s wheel path. The longer the trailer, the more you need to swing wide before turning. A common mistake: driving the truck through the turn as you normally would, and clipping the curb with the trailer wheel. To turn a 20′ trailer cleanly through a 90-degree right turn, you may need to swing left by a full lane before initiating the turn.
In a parking lot, take the longest path you can. Pull through pull-through spots when possible. Avoid drive-thrus.
Lane changes
Use mirrors, not over-the-shoulder checks — your trailer blocks the over-the-shoulder view anyway. Signal early. Move into the lane slowly and smoothly. A sharp lane change with a trailer is how sway starts.
Mirrors
Your trailer is almost certainly wider than your truck. By Texas law, your towing setup must have mirrors that show at least 200 feet behind you on each side. If your truck’s stock mirrors don’t, you need towing mirrors. Adjust them so you can just barely see the trailer’s side in the inside edge of each mirror, with the lane behind you in the outside edge.
Backing up
Backing a trailer is the hardest part of towing for new drivers. The rules:
- Steering wheel moves opposite the trailer. Bottom of the wheel goes the direction you want the trailer to go.
- Small inputs. Turn the wheel just a few degrees at a time. Wait. See what the trailer does. Correct.
- Use a spotter. Roll down both windows so you can hear them. Agree on hand signals before you start.
- Pull forward to reset. If the trailer is going the wrong way, don’t fight it — pull forward, straighten out, try again.
Practice in an empty parking lot. The Home Depot lot off Ben White is a good spot on a Sunday morning. Drop two cones, back between them, get comfortable.
Wind and weather
Texas is windy. I-10, I-35 south of Austin, and US-290 east are notorious for crosswinds. When a gust hits:
- Don’t oversteer. Hold the wheel firmly with both hands, make tiny corrections, ride it out.
- Slow down. Reducing speed by 5–10 mph reduces sway force significantly.
- Watch oncoming semis. They push a pressure wave that can yank you toward them, then push you away. Hold steady.
Rain doubles braking distance again. Hail and high wind warnings — get off the road. There’s no load worth being underneath a tree in a Texas hailstorm.
Highway driving
- Stay in the right lane except to pass.
- Use cruise control sparingly when loaded — you want your foot ready.
- Watch the temperature gauge on your truck. Towing in 100°F Texas heat heats engines fast; the climb up the hills around Dripping Springs or out to the Hill Country is where overheating happens.
- Plan fuel stops. Loaded trucks drink fuel faster than you expect — sometimes 30–40% more.
The good news: after about 50 miles, towing starts to feel normal. Stay calm, drive a little slower, give yourself space, and you’ll be fine.
