Illinois Free Test 1

Following another vehicle too closely, or tailgating, is the leading cause of rear-end crashes as it leaves insufficient distance to stop safely if the vehicle ahead brakes suddenly.

Night driving is more hazardous because darkness reduces visibility, making it harder to see pedestrians and roadway signs, and glare from other lights can be distracting.

Drivers should be aware that motorcyclists may need to change speed or lane position to avoid hazards and may rise off the seat over bumps like railroad crossings.

This sign warns of a steep hill ahead; drivers should be prepared to control their speed, possibly by shifting to a lower gear.

At a four-way stop, the first vehicle to stop is the first to go; if two vehicles stop at the same time, the vehicle on the right has the right-of-way.

This sign indicates the maximum legal speed allowed on this roadway under ideal driving conditions.

It is illegal and extremely dangerous to stop a vehicle on railroad tracks, as a train can appear at any time and requires a long distance to stop.

When being passed, Illinois law requires you to maintain your speed and stay in your lane; it is safest to slightly reduce your speed to allow the other driver to pass more easily.

Illinois law requires drivers to use their headlights from sunset to sunrise and during any period of poor visibility, such as rain, snow, or fog.

Warning signs are used to alert drivers to potential dangers ahead and locations where special rules may apply, requiring them to slow down and drive with caution.

On a road with two or more lanes traveling in the same direction, slower traffic should use the right-hand lane, leaving the left lane for passing.

A non-functioning traffic signal should be treated as a four-way stop; you must come to a complete stop and yield the right-of-way before proceeding.

Signs that are blue and white provide information on motorist services such as gas, food, lodging, and hospitals.

Motorcycles are less stable than cars and are more affected by adverse conditions; wet roads reduce braking, and road defects require them to maneuver within their lane.

At an uncontrolled intersection, if two vehicles arrive at the same time, the driver on the left must yield the right-of-way to the driver on the right.

Illinois law requires you to dim your high-beam headlights at least 300 feet before passing a vehicle traveling in the same direction.

Blue signs are a type of guide sign used to inform motorists of services such as gas, food, and lodging.

According to Illinois law, backing up on a roadway is only permitted when it can be done safely and without interfering with other traffic; it is prohibited on controlled-access highways.

Combining alcohol with other drugs can create a synergistic effect, greatly increasing the impairment of driving skills beyond what either substance would cause alone.

Due to their length, large trucks and buses often require extra space and may swing wide into an adjacent lane to complete a right-hand turn.

Motorcycles can stop much more quickly than cars, so you need to maintain a following distance of at least three to four seconds to have adequate time to react and avoid a collision.

When pulled over by law enforcement, you should stay inside your vehicle with your hands on the steering wheel and wait for the officer's instructions.

This sign warns of a curve to the right; slow down before entering the curve and do not pass other vehicles.

If your wheels go off the pavement, you should avoid sudden movements; grip the steering wheel firmly, ease off the accelerator, and brake gently to regain control before steering back onto the road.

If your steering fails, you should remove your foot from the gas pedal, turn on your emergency flashers, and allow the vehicle to slow down gradually as you move to the side of the road.
