A large truck moves somewhat left before turning right. What should you avoid?
Correct answer: Trying to squeeze past on its right.
Large vehicles may need room to complete a sharp right turn. The apparent opening beside the truck can close during the turn.

After overtaking a truck, what should you do before moving back ahead of it?
Correct answer: See its cab in your rearview mirror and leave ample space without braking sharply.
A truck needs more stopping space. Do not take away that cushion by cutting in closely or immediately slowing.

An oncoming pilot vehicle warns of an oversize load behind it. What should you do?

You are considering passing a snowplow. Which condition makes the pass especially unsafe?
Correct answer: The plow is spraying snow on the side where you would pass, obscuring the road.
Avoid unnecessary passing. Never pass on the side spraying snow, and do not cut back close to a blade that may be difficult to see.

You meet livestock being moved across a road under the direction of workers. What should you do?

The handbook directs drivers to yield to vehicles and pedestrians working on a highway construction project. Expect temporary movements and changing conditions.

You must stop for an approaching train. What stopping range does the handbook specify from the nearest rail?
Correct answer: At least 15 feet and no more than 50 feet.
Stop within 50 feet but not closer than 15 feet from the nearest rail. Do not enter until you can cross safely.

A railroad gate is down, but you cannot see a train. What should you do?
Correct answer: Remain stopped; never drive through, under or around the lowered gate.
A lowered or lowering gate is not optional. The train may be hard to see or approaching on another track.

Traffic beyond the tracks is stopped, leaving less than a car length of room. The crossing signals are not active. What should you do?
Correct answer: Wait before the tracks until there is room for your entire vehicle beyond them.
Never enter a crossing unless there is adequate space for the full vehicle on the other side. No part of the vehicle should wait on the tracks.

One train clears a crossing with more than one track. What must you check before proceeding when the warnings permit?
Correct answer: That no second train is approaching on another track and the crossing is safe.
A passing train can hide another. Check every track and obey the signals and gates before moving.

A first-time applicant is 14 years and nine months old and has begun training. What minimum age must the applicant reach for an Idaho driver license, even if the other requirements are met?
Correct answer: 15 years.
A license may be issued beginning at 15. The earlier driver-training permit age does not authorize an early license, and under-17 applicants must complete the required training and GDL process.

You enter a school zone with an active posted reduced speed limit. Which speed rule applies?
Correct answer: Obey that posted limit and slow further if children or conditions require it.
Observe posted school-zone limits. Continue to apply the basic safe-speed rule rather than treating the posted maximum as a required speed.

A police officer directs you to stop even though the signal facing you is green. What should you do?
Correct answer: Stop as directed by the officer.
The handbook requires stopping at an officer's request. Follow the active direction rather than using the green light as permission to proceed.

You reach the sign shown at a quiet intersection. What does it require even when no traffic is visible?
Correct answer: A complete stop before proceeding when safe.
STOP requires a full stop, not merely a reduction in speed. Use the stop line, or the appropriate crosswalk or intersection stopping position, then yield before proceeding.

What instruction does this triangular sign give as you approach crossing traffic?
Correct answer: Slow down and give way, stopping if necessary.
YIELD means give the right-of-way to traffic in the intersection or road you are entering. Slow enough to assess the situation and stop when needed.

This sign faces you at a roadway opening. Which action follows its instruction?
Correct answer: Do not use that opening to enter the roadway.
DO NOT ENTER prohibits entry from the direction you are approaching. An empty roadway does not cancel the restriction; find a lawful entrance.

You see this sign facing your vehicle after a turn. What danger does it identify?
Correct answer: You are traveling toward opposing traffic in the wrong direction.
WRONG WAY warns that you have entered against the permitted traffic direction. Correct the mistake as quickly and safely as possible; do not continue farther into oncoming traffic.

Which maneuver is ruled out by this symbol?
Correct answer: Turning left.
The red slash cancels the left-turn movement shown by the arrow. It does not itself prohibit going straight or establish priority over pedestrians.

A driver wants to turn in the direction crossed out on this sign. What should the driver do?
Correct answer: Continue by a permitted movement instead of turning right.
This is a NO RIGHT TURN regulatory sign. The crossed-out arrow prohibits the maneuver; it is not a yellow warning sign about the road bending.

What movement does this sign prohibit?
Correct answer: Turning around to travel in the opposite direction.
The U-shaped arrow identifies a U-turn. The sign prohibits that reversal of direction, rather than every possible movement involving a leftward steer.
