At a steady red light, a marked stop line lies before the crosswalk. Where should the front of your car be when you make the required stop?
Correct answer: Behind the stop line
Stop at the marked line. If there is no line, stop before the near crosswalk; if neither exists, stop before entering the intersection.

You are stopped at a circular red light and want to turn right. No sign prohibits the turn. What must happen before you may turn?
Correct answer: Yield to pedestrians, bicyclists, and conflicting traffic
Illinois permits the right turn after a complete stop unless it is prohibited. The permission does not give the turning driver priority over pedestrians, bicyclists, or conflicting traffic.

You are on a one-way street, stopped at red, and plan to turn left onto another one-way street carrying traffic to your left. No sign prohibits the turn. What does Illinois allow?
Correct answer: Turn left after yielding and finding a safe opening
The Illinois red-light exception includes a left turn from a one-way street onto a one-way street carrying traffic to the left. Stop first and yield; this does not authorize the same turn from a two-way street.

Your right-turn lane shows a steady red arrow. No sign prohibits turning on red. Under Illinois law, which action is permitted if the path is clear?
Correct answer: Stop completely, yield, and then turn right
Illinois applies its permitted right-turn-on-red exception to any steady red signal, including a red arrow. A full stop and yielding remain required, and a posted prohibition must be obeyed.

A green left arrow comes on, but a pedestrian who entered lawfully is still in the crosswalk your turn would cross. What should you do?
Correct answer: Yield until the pedestrian is clear of your path
A green arrow permits only its indicated movement, subject to yielding to people and traffic lawfully using the intersection or adjacent crosswalk.

Your light turns green while a vehicle that entered lawfully is finishing its crossing. What is the correct response?
Correct answer: Let that vehicle clear before entering its path
A circular green is permission to proceed, not permission to collide with traffic already lawfully in the intersection. Yield to that traffic.

A flashing yellow left arrow is displayed and oncoming traffic is approaching closely. What should you do?
Correct answer: Wait for a safe gap, yielding before making the left turn
A flashing yellow arrow permits a cautious turn only after yielding. For a left turn, oncoming vehicles close enough to be an immediate hazard must be allowed through.

At an ordinary street intersection, your traffic signal is flashing red. What procedure applies?
Correct answer: Stop completely, then proceed under stop-sign right-of-way rules
A flashing red traffic signal requires a stop and then the same right-of-way decisions as a stop sign. Railroad signals have separate rules.

Every lamp facing you at an ordinary traffic-light intersection is dark. This is not a pedestrian hybrid beacon, and no officer is directing traffic. What must you do?
Correct answer: Stop and follow the rules for a stop-sign intersection
An ordinary traffic signal with no illuminated light facing the driver requires a stop. The statute specifically excepts pedestrian hybrid beacons from this dark-signal rule.

A police officer directing an intersection signals you to stop even though your traffic light is green. Which instruction controls?
Correct answer: The officer's stop instruction
Follow the officer's direction. The normal duty to obey a traffic-control device is subject to an officer directing otherwise.

Two vehicles reach an uncontrolled intersection from different roads at approximately the same time. The other vehicle is on your right. Who should yield?
Correct answer: You should yield to the vehicle on your right
When no different control or special rule applies, the vehicle on the left yields to the vehicle on the right when arrival is approximately simultaneous.

You want to turn left into a driveway. An oncoming car is close enough that your turn would force it to brake sharply. What should you do?
Correct answer: Yield and wait for a safe interval
A left-turning driver must yield to oncoming traffic close enough to be an immediate hazard. Signaling does not transfer right of way.
