Review all 60 questions with answers

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. 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.

  12. 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.

    Source: Illinois Rules of the Road 2026, July 2026 DSD A112.47, Chapter 4 > Right of Way; Turning, printed p. 31 / physical p. 34; printed p. 26, physical PDF page 29.

  13. As you approach a yield sign, cross traffic leaves no safe gap. A stop line is marked before the crosswalk. What should you do?

    Correct answer: Stop at the line and wait until you can yield and enter safely

    A yield sign requires slowing and yielding, including a complete stop when needed for safety. The marked stop line is the first-choice stopping location.

  14. You are leaving a driveway in an urban area. A sidewalk extends across its mouth. Where must you first stop?

    Correct answer: Before driving into the sidewalk area

    Stop before entering the sidewalk area, yield to pedestrians as needed to avoid a collision, and then yield to vehicles on the roadway before entering it.

  15. There is no operating traffic signal. A pedestrian is already crossing within a marked crosswalk on your half of the roadway. What does Illinois require?

    Correct answer: Stop and yield to the pedestrian

    At a crosswalk without an operating signal, Illinois requires stopping and yielding when the pedestrian is on the driver's half of the roadway or approaching so closely from the other half as to be in danger.

  16. The vehicle ahead has stopped at an intersection crosswalk to let a pedestrian cross. The lane beside it appears open. What should you do?

    Correct answer: Do not overtake and pass the stopped vehicle

    Do not pass a vehicle stopped at a marked crosswalk or an unmarked intersection crosswalk to allow a pedestrian to cross. Its position may hide the pedestrian.

  17. You plan a turn in a business district. What is the minimum distance before the turn for a continuous turn signal under Illinois law?

    Correct answer: 100 feet

    Signal continuously for at least the last 100 feet in a business or residence district. Outside those districts, the minimum is 200 feet; the distinction is location.

    Source: Illinois Rules of the Road 2026, July 2026 DSD A112.47, Chapter 4 > Signaling; printed p. 30, physical PDF page 33. Current-law check: 625 ILCS 5/11-804(b), reviewed 2026-09-12. Full primary URLs, access status, and retained clauses: illinois-car-rules-2026-09-12.md. ↗

  18. You are outside a business or residence district and plan to turn into a farm entrance. How far in advance must you continuously signal at minimum?

    Correct answer: 200 feet

    Outside a business or residence district, Illinois requires a continuous signal for at least the last 200 feet before the turn. Signaling does not excuse an unsafe turn.

  19. A driver ahead flashes the right turn signal only to tell you that it is safe to pass. How should that use of the signal be understood?

    Correct answer: It is unauthorized; assess the pass yourself

    Illinois does not permit flashing a single-side turn signal as a courtesy invitation for a following vehicle to pass. A driver remains responsible for the legality and safety of the pass.

  20. There are no lane-control signs or markings requiring a different path. How should you approach and make a right turn?

    Correct answer: As close as practicable to the right-hand curb or roadway edge

    The ordinary right-turn rule is to approach and turn as close as practicable to the right curb or edge. Check for pedestrians and bicycles; special turn-lane markings can direct a different path.

  21. Official lane arrows and guide markings direct two adjacent lanes through a turn. What should determine your path?

    Correct answer: The designated path for your lane

    Official devices may prescribe a turn course different from the ordinary turning position. Follow the marked course and do not drift into the adjacent turning lane.

  22. A hillcrest prevents drivers in one direction from seeing your car until they are 400 feet away. May you make a U-turn there?

    Correct answer: No; the required visibility is at least 500 feet in either direction

    Illinois prohibits a U-turn on a curve or near a hillcrest when the vehicle cannot be seen within 500 feet by a driver approaching from either direction. A U-turn must also be safe and must not interfere with other traffic.

  23. Traffic is slow, and the shared two-way left-turn lane is empty. May you use it to drive ahead of the queue and then merge back?

    Correct answer: No; it is reserved for left turns or lawful U-turns, not through travel

    A designated two-way left-turn lane is not an extra through or passing lane. Use it only to prepare for or make a left turn from or into the roadway, or a U-turn when otherwise legal.

  24. You signal a lane change, but another vehicle is alongside you in that lane. What does your signal permit?

    Correct answer: No immediate lane change; wait until the movement can be made safely

    A signal communicates intent; it does not create right of way. Remain within your lane until you have determined that the movement can be made safely.

  25. Two same-direction lanes are separated by double solid white lines. What do those lines tell you?

    Correct answer: Do not cross them to change lanes

    The Illinois handbook distinguishes a single solid white line, where lane changes are discouraged, from double solid white lines, which prohibit crossing.

  26. A driveway is on your left across double solid yellow centerlines. No sign prohibits the turn, and you can turn safely after yielding. What do the centerlines allow?

    Correct answer: A left turn into the driveway, although ordinary passing is prohibited

    Double yellow centerlines prohibit ordinary passing in both directions, but they do not by themselves prohibit a safe left turn into or out of a driveway. Obey other restrictions and yield to oncoming traffic.

  27. You enter an ordinary roundabout after yielding to circulating traffic. Which way should you travel around its center island?

    Correct answer: Counterclockwise, keeping the island on your left

    Illinois directs vehicles to pass to the right of a rotary traffic island. At an ordinary roundabout this means circulating counterclockwise; yield before entry and follow lane markings.

  28. Another vehicle has begun a lawful pass on your left. What must you avoid doing until it has completely passed?

    Correct answer: Increasing your speed

    A driver being overtaken must not increase speed until the other vehicle has completely passed. Speeding up lengthens the pass and can create a conflict.

  29. A car ahead is waiting to turn left. There is no travel lane to its right, but the paved shoulder is wide. May you use the shoulder to pass it in an ordinary car?

    Correct answer: No; a wide shoulder is not a passing lane

    Passing on the right is allowed only under lawful roadway conditions and when safe. A paved shoulder does not become a travel lane merely because there is space to get around a turning car.

  30. On a two-way road, you would finish a left-side pass and return right when an oncoming car is only 150 feet away. Does that meet Illinois's minimum oncoming clearance rule?

    Correct answer: No; return right before coming within 200 feet of an oncoming vehicle

    Do not begin a pass unless there is enough clear roadway to complete it without interfering with traffic. Illinois also requires returning to the authorized lane before coming within 200 feet of an approaching vehicle.

  31. You are on a two-lane, two-way road, and an intersection is 80 feet ahead. You want to cross the centerline only to pass a slower car. No statutory exception applies. Is that allowed?

    Correct answer: No; you are within the 100-foot intersection restriction

    The statutory restriction applies within 100 feet of or while traversing an intersection or railroad grade crossing. A broken centerline alone does not remove that restriction; separate statutory exceptions are not ordinary passing permission.

  33. You are overtaking a bicyclist. Another same-direction lane is available, and changing into it is safe, practicable, and legal. What must you do?

    Correct answer: Change lanes and maintain at least 3 feet of safe passing clearance

    Current Illinois law calls for the available, safe, practicable, lawful lane change before overtaking a bicycle. It separately requires a safe passing distance of at least 3 feet, maintained until safely past.

  35. On a 40-mph road, a bicyclist is traveling at 15 mph in a marked no-passing zone. Which statement correctly describes Illinois's limited bicycle-passing exception?

    Correct answer: It may apply only if all safe-clearance, visibility, distance, and speed-limit conditions are satisfied

    The bicycle must be traveling below half the posted limit, the motorist must not exceed that limit, and sufficient safe passing space must exist. Section 11-703(d) clearance/lane-change duties and Section 11-706 restrictions still apply; the speed fact alone does not authorize a pass.
