Towing changes how your vehicle steers, brakes and handles. Class C drivers have strict size limits, and a trailer that's overloaded or badly balanced can overturn or throw its load onto the road.

10,000 lb

Most a non-commercial Class C driver may tow — single vehicle or combination, by GVWR

70 feet

Maximum total length of a Class C driver's towing combination

Know the rule

Handbook p. 68 ↗

Know the rule

Loading a trailer incorrectly endangers you and others: items that come loose can hit other road users, and the trailer's interior can be damaged in a quick stop or crash.

Handbook p. 68 ↗

Know the rule

Overloading hurts steering, braking and speed control: very slow on uphill grades, too fast downhill, longer stopping distances, and brakes that can fail when forced to work too hard.

Weight terms

Weight terms
TermMeaning
Gross vehicle weight (GVW)Total weight of a single vehicle plus its load
Gross combination weight (GCW)Power unit + trailer(s) + load, all together
Gross combination weight rating (GCWR)Maker's rated combined loaded weight, vehicle + trailer
Axle weightWeight one axle or set of axles puts on the ground
Tire loadMax safe weight a tire can carry at a stated pressure
Suspension / coupling deviceEach has a maker's weight capacity rating
Handbook p. 68 ↗

Know the rule

Don't be top-heavy: the higher the center of gravity, the more likely you'll overturn. Keep cargo as low as possible — heaviest items under the lightest, or in lower storage compartments.

Handbook p. 69 ↗

Balance problems:

  • Too much weight on the steering axle — hard steering, damaged axle and tires
  • Too little on the front (weight shifted too far back) — steering axle too light to steer safely
  • Too little on the drive axles — poor traction; drive wheels spin easily
  • Too much on one side of the trailer — can overturn, especially in turns
Handbook p. 69 ↗

Two ways to prevent a rollover:

  • Go slowly around turns
  • Keep the cargo as close to the ground as possible
Handbook p. 69 ↗

Know the rule

Rollovers are also more likely if you must swerve in a turn or curve. On flatbed trailers, the load is more likely to shift sideways or fall off.

Handbook p. 69 ↗

Put it into practice

You're loading a utility trailer with a heavy generator and light camping gear. Put the generator low and centered and the light gear above it — stacking the generator high would raise the center of gravity and invite a rollover.

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.

A non-commercial Class C driver may tow a vehicle or combination with a GVWR of:
  1. 10,000 pounds or less
  2. 15,000 pounds or less
  3. 5,000 pounds or less
  4. 26,000 pounds or less

Answer: 10,000 pounds or less

Non-commercial Class C drivers may tow a vehicle or combination with a GVWR of 10,000 lbs or less.

Handbook p. 68 ↗
The total combined length of a Class C driver's towing combination may not exceed:
  1. 50 feet
  2. 70 feet
  3. 100 feet
  4. 40 feet

Answer: 70 feet

The combination may not exceed a total length of 70 feet.

Handbook p. 68 ↗
Gross Vehicle Weight (GVW) refers to:
  1. The weight of the trailer only
  2. The weight specified only by the manufacturer's rating
  3. The total weight of a single vehicle plus its load
  4. The empty weight of the vehicle

Answer: The total weight of a single vehicle plus its load

GVW is the total weight of a single vehicle plus its load.

Handbook p. 68 ↗
Gross Combination Weight Rating (GCWR) is:
  1. The actual weight currently on the truck
  2. Only the weight of the cargo
  3. The weight limit for a single axle
  4. The maker's max combined weight rating

Answer: The maker's max combined weight rating

GCWR is the manufacturer-specified maximum combined loaded weight of a vehicle and trailer.

Handbook p. 68 ↗
To help prevent a rollover, heavy cargo should be:
  1. Piled as high as possible for visibility
  2. Kept as low to the ground as possible
  3. Placed only on one side for balance
  4. Placed at the very rear of the trailer

Answer: Kept as low to the ground as possible

Distribute cargo so it is as low to the ground as possible to reduce rollover risk.

Handbook p. 68 ↗
Where should the heaviest items be placed in a loaded trailer?
  1. On top of lighter items for easy access
  2. Evenly distributed regardless of height
  3. Under lighter items or in lower compartments
  4. At the very rear of the trailer only

Answer: Under lighter items or in lower compartments

Put the heaviest items under the lightest parts or in lower storage compartments.
