Illinois Driving Permit Practice Test

What equipment must all vehicles have when driven on public roads?

1. Air conditioning and radio

2. Windshield wipers and defrosters

3. Working headlights, taillights, brake lights, and turn signals

4. Seat belts and emergency flares

The correct answer is: Working headlights, taillights, brake lights, and turn signals

All vehicles operating on public roads are required to have working headlights, taillights, brake lights, and turn signals. These pieces of equipment are essential for safe driving, as they provide visibility to the driver and communicate intentions to other road users. Headlights illuminate the road ahead during nighttime or in low visibility conditions, while taillights indicate the presence of a vehicle to those behind it. Brake lights signal when a driver is slowing down or stopping, and turn signals alert others of a driver’s intention to change lanes or make turns. This equipment is critical for reducing the risk of accidents and ensuring that all road users can respond appropriately to a vehicle's actions on the road.
