Your signal is red and you intend to continue straight. The intersection appears empty. What must you do?
Correct answer: Stop and wait for a signal permitting your movement.
A steady red signal requires a stop. An empty intersection does not authorize a straight-through movement against it.

A flashing red light controls your approach to a rural junction. What is the correct sequence?

Your light turns yellow while you still have enough distance to stop safely. What should you do?

Yellow warns of an approaching red signal. Stop when you can do so safely; drivers already in the intersection should complete their movement cautiously.

A flashing yellow signal faces you at an intersection. How should you approach?

Your light turns green, but cars ahead leave no room beyond the intersection. What should you do?
Correct answer: Wait until you can enter without blocking the intersection.
A green signal is permission to proceed only when the path is clear. Do not block the intersection or disregard people and vehicles already there.

You are turning left on a flashing yellow arrow while an oncoming car approaches. What does the arrow require?
Correct answer: Yield to the oncoming car and pedestrians before turning.
A flashing yellow arrow allows a cautious turn after yielding. It is not a protected turn ahead of oncoming traffic.

A green arrow permits your turn, but a pedestrian is still crossing your path. What should you do?
Correct answer: Yield until the pedestrian has cleared your path.
A green arrow permits the indicated movement but does not cancel the duty to yield to people or vehicles already in the intersection.

The reversible lane above your car displays a steady yellow X. What should you plan to do?
Correct answer: Leave that lane as soon as it is safe.
A steady yellow X warns that the lane is changing use. Move out safely rather than continuing until opposing traffic arrives.

You are choosing a lane controlled by overhead signals. What does a red X over a lane mean?
Correct answer: Do not drive in that lane.
A red X closes that lane to traffic moving in your direction. Do not enter it because adjacent lanes are crowded.

A pedestrian hybrid beacon changes to steady red as you approach its crosswalk. What must you do?
Correct answer: Stop and remain stopped during the steady red indication.
The steady red phase requires drivers to stop. The later flashing-red phase has a different stop-and-proceed-when-clear instruction.

You have stopped at a pedestrian hybrid beacon. It now flashes red and the crossing is clear. What may you do?
Correct answer: Proceed cautiously after checking that the way remains clear.
At flashing red, each approaching driver must first stop if not already stopped, then may proceed when the crossing is clear.

A road has a yellow centerline and white lines between lanes on your side. What do those colors ordinarily separate?
Correct answer: Yellow separates opposing directions; white separates same-direction lanes.
Iowa describes yellow lines as separating opposite directions and white lane lines as separating traffic moving in the same direction. This is a text-based color distinction, not a claim about an unseen diagram.

Two cars reach an all-way stop at the same time. The other car is on your right. Both plan to go straight. What should you do?
Correct answer: Yield to the car on your right.
When drivers arrive at the same time, the driver on the left yields to the driver on the right. Check that the other driver is actually proceeding safely.

Another vehicle has already stopped at an all-way stop before you arrive. What determines who normally proceeds first?
Correct answer: The driver who stopped first normally proceeds first when safe.
At an all-way stop, arrival order normally determines priority. The simultaneous-arrival rule does not displace a vehicle that stopped first.

You want to turn left at an intersection without a protected turn signal. An oncoming vehicle is going straight. What must you do?
Correct answer: Yield and wait for a safe gap before crossing its path.
A driver turning left must yield to oncoming traffic going straight. Signaling your intention does not give you priority.

You are leaving a driveway that crosses a sidewalk before reaching the street. A person is approaching on the sidewalk. What should you do?
Correct answer: Stop before the sidewalk and yield before entering the street.
Drivers leaving a private drive must stop before crossing the sidewalk and yield to pedestrians and traffic on the public road.

No sign prohibits a right turn on red. After stopping, you see a pedestrian crossing the road you would enter. What should you do?
Correct answer: Wait for the pedestrian and any conflicting traffic before turning.
A permitted right turn on red still requires a full stop and yielding to pedestrians and conflicting traffic.

A bicyclist enters your path when the bicyclist should have yielded. You have room to slow safely. What is your responsibility?
Correct answer: Slow or stop as needed to prevent a collision.
Right-of-way rules do not excuse a driver from avoiding a collision. Take a safe defensive action even when another road user makes the mistake.

A car approaching from your left has its right-turn signal on. You are waiting to enter its road. What is safest?
Correct answer: Wait until its movement confirms the turn and your path is clear.
An indicator can be left on or activated early. Confirm the vehicle is actually turning before relying on that opening.

Cars are circulating in a roundabout as you approach the entrance. Who must yield?
