A 3-minute lesson from the Illinois course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Some equipment is limited or banned because it can blind, confuse or endanger other drivers. Rules cover long loads, extra lights, studded tires, screens and radar jammers.
Know the rule
A load extending 4 feet or more past the rear of a vehicle must be marked with a red flag during the day. At night or in poor visibility, it needs a red light visible for 500 feet.
Only one spotlight is allowed. When approaching another vehicle, aim it neither to the left nor more than 100 feet ahead. No more than four 300-candlepower lights may be burning.
Flashing or moving lights other than turn signals and hazard indicators are prohibited, except on police and designated emergency vehicles (including fire protection district vehicles).
Televisions or video monitors visible from the driver's seat are prohibited while the vehicle is moving. Watching or streaming live video on a cellphone is also a violation.
You're hauling a ladder that sticks out 5 feet behind your pickup in the afternoon. Tie a red flag to the end. If you're still driving after dark, you'll need a red light visible for 500 feet.
