California roads vary because of the state's various geographical demographics. Because of the height of tunnels and overpasses in the state, the maximum height of an RV trailer is 14 feet. This law is valid for any type of RV. When measuring the height of your RV remember to include anything that protrudes above the roof including your air conditioner, antenna and vent cover. The maximum length of a tow vehicle and its travel trailer or fifth wheel in California is 65 feet with a width of 102 inches. In certain areas you can triple the tow (or have two trailers behind a tow vehicle).
Travel trailer and fifth wheels are required to have running lights in the state of California. This refers to brake lights and turn signals. The running lights let other drivers know you're pulling a trailer and also lets them know the length and width of the trailer. Running lights are a safety feature for other drivers on the road because RV trailers are much larger than the average car.
If you're towing something more than 1,500 pounds, you must have trailer brakes and a breakaway switch that releases the trailer in an emergency. In California, people cannot ride in a towed trailer but can inside a fifth-wheel trailer. A camper with someone riding in it must have an unblocked and unlocked exit door that can be opened from the inside as well as the outside.
