Illinois Required Vehicle Equipment Laws

To be a safe driver, a vehicle must be properly equipped and in good working order. It is illegal to drive a vehicle that may be a hazard to any person or property.

Required Equipment

A motor vehicle must have the following working equipment:


Vehicles must have two brake systems and brakes on all wheels. The foot brake must be strong enough to stop a vehicle traveling at a speed of 20 mph in 30 feet. The emergency or parking brake must be strong enough to stop the vehicle in 55 feet at the same speed.

The emergency brake also must be able to hold the vehicle on a grade or hill. Motor-driven cycles need only one brake.


Vehicles must have two headlights and they must be on from sunset to sunrise and be used in times when rain, snow, fog or other conditions require the use of windshield wipers. They also should be used when objects 1,000 feet away cannot be seen. Bright lights must be dimmed 500 feet before meeting an oncoming vehicle or 300 feet before passing a vehicle.

Motorcycles and mopeds require a headlight, which must show objects 500 feet ahead, and be turned on whenever the vehicle is driven.


Vehicles must have two red lights visible for 500 feet from behind. Only one taillight is needed for mopeds and motorcycles.

Turn signals

Vehicles, except motorcycles, trailers and semitrailers, must have right and left-turn signals on the front and rear visible from 300 feet.

License plate light

Vehicles must have a white light making the license plate readable from 50 feet away and must be on when headlights are on.

Parking lights

Front and rear parking lights are required for any vehicle stopped on a highway at night. Some local communities may allow unlighted night parking on streets.

Safety Belts

Passenger vehicles must have two sets of safety belts in the front seat. Vehicles manufactured in 1965 or after may not be sold or operated in Illinois without safety belts.


One rearview mirror is required so the driver can see at least 200 feet behind the car.


All window glass must be approved safety glass. The windshield must be free of snow, ice, moisture and any defects that distort vision. All glass must be free of obstructions between the driver and front or rear windows.

Tinted windows are not allowed on the front windshield. A 6-inch strip of tinting is allowed along the entire length at the top of the front windshield.


Wipers must operate properly to clear ice, snow and moisture.


Vehicles must have a horn that can be heard from 200 feet. Sirens, whistles and bells are allowed only on authorized emergency vehicles.


A muffler must be on the exhaust system to prevent excessive noise and smoke. Cutouts, bypasses and changes to the system to increase noise are illegal.


Vehicles weighing 9,000 pounds or less and all recreational vehicles must have a front and rear bumper. It is illegal to alter the suspension system of a vehicle to lift the body from the chassis frame in excess of 3 inches. The horizontal line from the front to the rear may not vary over 3 inches.
