4 Michigan Trailer Light Requirements You Should Know

Trailer Light Requirements in Michigan

Trailer light requirements vary from state to state. The following regulations are required by Michigan law. If you plan to leave the state, check the trailer light requirements in the states you will be visiting.

In addition, trailer light connection failure is a common problem that poses a serious safety hazard. Therefore, travelers should make sure all trailer lights are working before heading out on the road.

For trailers, pickup campers or semi trailers weighing more than 3,000 pounds:

Front:

• Two clearance lamps (one on each side).

On each side:

• Two side marker lamps (one at or near the front and one at or near the rear).

• Two reflectors (one at or near the front and one at or near the rear).

Rear:

• Two clearance lamps (one at each side).
• Two reflectors (one at each side).
• One stop light.

For pole trailers:

On each side:

• One side marker lamp.

• One clearance lamp.

These may be in combination and may show to the front, side or rear.

Rear:

For trailers, pickup campers or semi trailers weighing 3,000 pounds gross or less:

Front:

• Two clearance lamps, one at each side.

On each side:

• Two side marker lamps, one at or near the front and one at or near the rear.

• Two reflectors, one at or near the front and one at or near the rear.

Rear:

• Two reflectors, one on each side.

• Two clearance lamps, one at each side.

• One stop light.

• An additional stop light if the standard stop light is obscured due to the towing vehicle’s load or dimensions.

• At least one rear lamp that emits a red light plainly visible from a distance of 500 feet.

• A white light that illuminates the rear registration plate so it is visible from a distance of 50 feet.

Additional Regulations For Recreational Doubles

A “recreational double” is a pickup truck pulling a fifth wheel trailer, such as an RV, with a second trailer attached to its rear.

Operating a recreational double requires drivers to have an “R” endorsement on their license. To obtain this endorsement, drivers must pay $10 and pass a knowledge test administered by the Secretary of State.

In addition to the general rules for trailers, there are extra regulations that drivers of these vehicles must comply with. Here are a few:

• The total combined length of the three units — pickup truck, fifth-wheel trailer and second trailer — must not exceed 75 feet.
• The gross weight of the second trailer cannot exceed the empty weight of the pickup truck or the empty weight of the fifth-wheel trailer.
• A trailer cannot drift more than three inches to either side of the path of the towing vehicle when traveling in a straight line on a level, smooth, paved surface. 

“With its abundance of lakes and scenic locations, Michigan provides many opportunities for boating and camping,” says Mark Bernstein of The Sam Bernstein Law Firm. “Motorists who adhere to rules such as trailer light requirements make our roads safer for everyone.”

Auto accident law is complicated, but finding the right lawyer is simple.
