Driver error contributes to the large majority of crashes involving vehicle-trailer combinations. You can't change the vehicle to fit your habits—you must change your driving to fit the vehicle: slower pace, more space, more planning.

60% / 40%

Cargo weight split: 60% in the front of the trailer (nearest the tow vehicle), 40% in the back

Handbook p. 75 ↗

Know the rule

Load trailers heavier in front to reduce sway. Failing to do so is a leading cause of vehicle-trailer mishaps.

Place 60% of cargo weight in the trailer front

If the trailer sways or whips:

  • Steer straight and reduce speed gradually
  • Don't apply the brakes, and never speed up
  • Stop as soon as you can get completely off the road
  • Check that the load is heavier in front; reload if needed
  • Keep heavy items on the floor and tie down partial loads

55 mph

Maximum recommended speed for most vehicle-trailer combinations

Handbook p. 76 ↗

Driving with a trailer:

  • Drive more slowly; never exceed the posted limit, and slow more when conditions worsen
  • Slow down BEFORE starting down a grade
  • Leave extra following distance—even more in rain, snow or fog
  • Allow more distance to pass, especially on hills or curves
  • Give the trailer extra room on turns—it doesn't follow directly behind the car
Handbook p. 76 ↗

Know the rule

Backing a trailer: go slowly with your hand at the bottom of the wheel. Move your hand left to move the trailer left, right to move it right. If it starts to jackknife, STOP, pull ahead to straighten out, then start again.

Handbook p. 76 ↗

'Pro' tips:

  • Unsure how to hook up, load or drive with a trailer? Ask a trailer professional
  • Before driving and at each fuel stop, recheck hitch, coupler, safety chains, lights and tire pressures
  • Hear an unusual noise? Stop at a safe place off the road and check
  • Don't drive 'straight through' on long trips—plan rests so you drive rested in daylight
Handbook p. 76 ↗

Safe trailering checklist:

  • Load heavier in front; load secure
  • Hitch tight; chains attached
  • Lights working; tire pressures OK
  • Reduce speed; think ahead
  • Stop often for rest; inspect often
  • Wear your seat belt
Handbook p. 76 ↗

Put it into practice

On the interstate your camper trailer starts to fishtail. Keep the wheel straight and ease off the gas so speed drops gradually—no brakes, no acceleration. Then pull completely off the road and check that the load is heavier in front.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

When loading a trailer, what percentage of cargo weight should go in the front, nearest the towing vehicle?
  1. 50 percent
  2. 40 percent
  3. 75 percent
  4. 60 percent

Answer: 60 percent

Sixty percent of the cargo weight should go in the front of the trailer and 40 percent in the back.

If a trailer begins to sway or whip while driving, you should:
  1. Apply the brakes hard immediately
  2. Turn sharply to correct the sway
  3. Steer straight and reduce speed gradually, without braking
  4. Increase speed to stabilize it

Answer: Steer straight and reduce speed gradually, without braking

Steer straight and reduce speed gradually if a trailer sways; do not apply the brakes, which can worsen the sway.

Handbook p. 76 ↗
The maximum recommended speed for most vehicle-trailer combinations is:
  1. 65 mph
  2. 55 mph
  3. 45 mph
  4. 70 mph

Answer: 55 mph

The maximum recommended speed for most vehicle-trailer combinations is 55 mph.

When backing up a trailer, to move the trailer to the left you should move your hand (placed at the bottom of the wheel):
  1. Straight down
  2. Straight up
  3. To the right
  4. To the left

Answer: To the left

With your hand at the bottom of the wheel, move it left to steer the trailer left, and right to steer it right.

Handbook p. 76 ↗
If a trailer begins to jackknife while backing up, you should:
  1. Apply the trailer brakes only
  2. Continue backing while steering hard
  3. Stop and pull ahead to straighten out, then start again
  4. Speed up to straighten it

Answer: Stop and pull ahead to straighten out, then start again

If the trailer starts to jackknife, stop, pull forward to straighten it, then begin backing again.

Handbook p. 76 ↗
Before driving with a trailer and at each fuel stop, you should:
  1. Only check the fuel gauge
  2. Check the hitch once before the entire trip only
  3. Walk around and recheck the hitch, chains, lights, and tire pressures
  4. Inspect only the tow vehicle, not the trailer

Answer: Walk around and recheck the hitch, chains, lights, and tire pressures

Walk around the vehicle-trailer combination at each stop to recheck the hitch, chains, lights, and tire pressures.
