RV driving basics: how to handle a big rig on the road
How to handle weight, height, wide turns, mountain grades and long days in an RV
Renting or buying an RV can feel like freedom on wheels. But for many people, it is the biggest and heaviest vehicle they will ever drive, and they get the keys with little or no training. A large motorhome can be more than 40 feet long and weigh as much as a loaded delivery truck.
The skills are learnable. This guide covers what every new RV driver should know before heading out, whether you drive a motorhome or tow a travel trailer or fifth wheel.
Know your numbers
Height. Measure from the ground to the highest point, including the air conditioner, vents and antennas. Write it on a note on the dashboard. Low bridges, gas station canopies, parking garages and tree branches are common RV hazards.
Length and width. These affect turns, lane changes and where you can park. Some campgrounds and roads have length limits.
Weight. Every RV has a gross vehicle weight rating (GVWR), the most it can weigh fully loaded [1]. Water, propane, food, gear and passengers add up fast. A full fresh water tank alone can add hundreds of pounds. Weigh your loaded RV at a truck stop scale before a long trip.
Driving differences
Stopping. Heavy vehicles need much more distance to stop. Leave far more following distance than you would in a car. Brake early and gently [1].
Turning. Make wide turns. On a right turn, pull farther into the intersection before turning so the rear wheels clear the curb [1]. Watch for tail swing, where the back of a long RV swings out the opposite way when you turn.
Lane position. Stay centered. RVs fill most of a lane, so drifting even a little can clip mirrors or hit the shoulder.
Mirrors and blind spots. Adjust mirrors before driving. Use a backup camera if you have one. Signal early and change lanes slowly.
Wind. Tall RVs catch crosswinds. Slow down on windy days and when big trucks pass. Pull over if gusts make it hard to stay in your lane.
Mountain grades
- Going up: Expect to slow down. Use the right lane and turn on hazard lights if you are much slower than traffic.
- Going down: Shift to a lower gear before the descent. Let the engine slow you. Brake firmly in short bursts, then release. Riding the brakes can overheat them until they fail.
- Watch the signs for steep grades, runaway truck ramps and truck speed limits. They often apply to RVs too.
Backing and parking
Use the rule many RVers live by: get out and look. Walk around the RV before backing. Use a spotter and agree on hand signals or use phones. If you lose sight of your spotter, stop.
Plan easier travel days
Many experienced RVers limit how far they drive each day and aim to arrive before dark. Driving tired in a heavy vehicle is dangerous. Arriving in daylight makes it far easier to find and back into a campsite.
Plan fuel stops at stations with tall canopies and room for large vehicles, such as truck stops. Use navigation apps made for RVs, which can route around low bridges and roads that ban large vehicles.
Tires: the RV weak spot
RVs often sit for months between trips, and their tires can age out before the tread wears down. Check the date code on every tire [2]. Check pressure before each travel day, when tires are cold. Underinflated tires on a heavy RV can overheat and blow out.
If a tire blows out, hold the wheel firmly and keep the RV straight. Gently press the gas for a moment to keep control, then slow down gradually. Do not slam the brakes.
Inside the RV
- Buckle up. In a motorhome, passengers should ride in seats with seat belts. A loose person or object becomes a projectile in a crash.
- No riders in travel trailers. Never let anyone ride in a towed trailer while moving. Many states ban it.
- Secure everything. Latch cabinets, close the fridge and stow loose items.
- Propane. Turn off propane appliances while driving and while refueling. Test carbon monoxide and propane alarms before each trip.
Warning: Never run a generator while people sleep unless the RV’s carbon monoxide alarm works and exhaust cannot drift inside. Carbon monoxide has no smell and can kill.
Checklist: before every RV travel day
Checklist from Safety Behind the Wheel Foundation
- Height and weight are written where the driver can see them
- Tire pressure checked cold, and tire date codes are within limits
- Mirrors adjusted and backup camera working
- Cabinets, doors, steps, slides and awnings closed and locked
- Propane off for travel and fueling
- Everyone in a belted seat
- Route checked for low clearances and fuel stops
- Arrival planned before dark
Frequently asked questions
Do I need a special license to drive an RV?
In most states, a regular driver’s license covers most RVs. A few states require a special license for the largest RVs, often based on weight or length. Check with your state driver licensing agency.
Should I take a class before driving an RV?
It is a smart idea. Some RV dealers, rental companies and RV clubs offer driving courses. At a minimum, practice in an empty lot.
Can I tow a car behind my motorhome?
Yes, many people do. Check your motorhome’s towing capacity and the car maker’s instructions for flat towing. Use supplemental brakes if your state or the weight requires them.
