You are behind a school bus stopped with its red lights flashing and stop arm extended. What must you do?
Correct answer: Stop behind it and wait; do not pass while the stop arm remains extended.
Traffic behind the bus must stop for its active stop signal. A clear lane or another driver passing does not cancel the protection for children.

You approach a stopped school bus from the opposite direction on a road with one travel lane each way and a center turn lane. Its stop arm is extended. What must you do?
Correct answer: Stop; the center turn lane does not create two travel lanes in each direction.
The opposite-direction exception applies to roads with two or more travel lanes in each direction, not a three-lane road with a center turn lane.

You approach a stopped school bus from the opposite direction on a road with two travel lanes in each direction. What does the manual say about the bus stop requirement?
Correct answer: Opposite-direction traffic is not required to stop for that bus.
The manual distinguishes four-or-more-lane roads with at least two travel lanes in each direction. Traffic following the bus must still stop; the opposite-direction exception does not authorize ignoring other hazards.

A passenger car is stopped on the shoulder with hazard flashers on. You can safely change to a lane farther away. What should you do?

You approach a stopped vehicle with warning lights, but adjacent traffic prevents a safe lane change. What should you do?

A work-zone flagger tells your lane to stop, although your usual route would continue ahead. What should you do?
Correct answer: Stop and follow the flagger’s direction.
Authorized work-zone control directs traffic through temporary hazards. Follow the flagger and leave extra room rather than relying on the usual road arrangement.

A person is crossing at an intersection in an unmarked crosswalk. What should you do?
Correct answer: Yield; the absence of painted lines does not remove the crosswalk protection.
The manual requires yielding to pedestrians in both marked and unmarked crosswalks. Watch at intersections even when no paint marks the crossing.

A person using a wheelchair is crossing in your path at a crosswalk. How should you treat that person?
Correct answer: Yield as you would to a pedestrian walking across.
Iowa’s pedestrian guidance includes people using mobility conveyances. A wheelchair user in the crossing needs the same safe yielding response as a person on foot.

A vehicle in the next lane has stopped just before a crosswalk and blocks your view. What should you do?
Correct answer: Do not pass it; be ready for a pedestrian hidden by the vehicle.
A stopped vehicle may hide a crossing pedestrian. Do not overtake a vehicle stopped for a person at a crossing.

A truck ahead moves left as it prepares a right turn. An opening appears on its right. What should you do?
Correct answer: Stay back rather than driving into the opening.
Large trucks may need extra space to turn right. Entering the space beside the truck can put your car in the path of the trailer.

You have been traveling alongside a large truck near its rear wheels. What is a safer position?
Correct answer: Move out of its blind spot when you can do so safely.
Large vehicles have extensive blind spots. Avoid lingering beside them, and keep enough space to be visible and to react.

A motorcyclist occupies only part of the lane ahead. May you squeeze beside the motorcycle within that lane to pass?
Correct answer: No; allow the motorcycle a full lane.
Motorcyclists need the full lane to adjust position and avoid hazards. Do not treat unused-looking space within their lane as a passing lane.

You plan to turn right after passing a bicyclist. What should you check before crossing the bicyclist’s path?
Correct answer: Look beside and behind, and wait if the turn would cut off the bicyclist.
A bicyclist can reach the intersection while you are preparing to turn. Check for the rider and do not turn across the rider’s path unsafely.

A wide farm vehicle ahead slows near an unmarked field entrance. What is the best response?
Correct answer: Stay back and allow room for an unexpected or wide turn.
Farm equipment may turn into field entrances that are difficult to see. Its width and turning path require patience and extra space.
