A 3-minute lesson from the Idaho course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Some add-ons are illegal on ordinary cars, and some everyday rules cover your lights, windows, and cargo. These are easy test points because each comes with a specific number or date.
Equipment NOT allowed:
Red or blue emergency lights (emergency vehicles only)
Sirens, bells, and whistles
Any muffler cut-out or bypass that makes the exhaust louder
More than two spotlights
More than two auxiliary lights, or more than two fog lights, in front
Keep windows clean of signs, posters, and stickers except those required by law, and clear ice, snow, or dirt before driving. Passengers or freight may not block your view or interfere with driving.
You're hauling lumber that sticks out 5 feet behind your pickup after dark. Because it extends 4 feet or more, you must mount a red light at the end of the load that's visible for at least 500 feet.
Check your understanding
