3 questions from the Illinois practice test
1. When entering a roundabout, whom must a driver yield to?
- Only vehicles approaching from the left
- All traffic, including pedestrians and bicycles
- No one, because entering traffic has priority
- Only vehicles already stopped outside the circle
Show answer
All traffic, including pedestrians and bicycles. Vehicles entering or exiting an Illinois roundabout must yield to all traffic, and the manual specifically includes pedestrians and bicycles. Entering drivers should slow down, read the signs and pavement markings, and wait for a safe opening before turning right into the circle. Priority does not belong automatically to a vehicle entering, and the rule is broader than watching one side or only stopped vehicles. Look for users already circulating and for people crossing near the entry or exit.
2. How should a driver approach a slow-moving vehicle from the rear?
- Follow closely until the operator notices
- Pass immediately because the vehicle cannot turn
- Prepare to slow down and pass only when it is safe
- Use the shoulder to avoid waiting
Show answer
Prepare to slow down and pass only when it is safe. Farm vehicles, construction equipment, and animal-drawn vehicles may share Illinois roads, and drivers approaching from behind should use caution and prepare to slow down. A slow-moving vehicle may be wide and may turn right or left into an unmarked entrance, so following closely or assuming it cannot turn is unsafe. The shoulder is not a substitute for a legal passing movement. Stay a safe distance back, make sure the operator knows your presence and intent, and pass only with adequate space and visibility.
3. What should a driver do when meeting or passing a horseback rider?
- Sound the horn repeatedly before passing
- Accelerate past the animal with little clearance
- Pass cautiously and be prepared to stop
- Drive onto the shoulder to pass immediately
Show answer
Pass cautiously and be prepared to stop. A horse may react unpredictably to noise or a close vehicle. Illinois says to pass a horseback rider with caution and be prepared to stop, while separately warning drivers never to sound a horn near a horse or other livestock. Repeated honking can frighten the animal and cause a crash. Slow down, leave useful clearance, and wait when the rider’s movement or road width makes passing uncertain.
