You enter a freeway using an acceleration lane. Who has the yielding duty at the merge?
Correct answer: You must yield to traffic already on the freeway and choose a safe gap.
Adjust speed to blend safely, signal and check the gap. The entering driver must yield rather than force a freeway vehicle to avoid a crash.

A short acceleration lane and heavy traffic leave no safe merging gap. What should you do?
Correct answer: Slow or stop if necessary, leaving room to accelerate when a safe gap opens.
Some entrances require slowing or stopping when no safe opening exists. Leave room to accelerate and enter only without interfering with freeway traffic.

You pass your intended freeway exit. What should you do?
Correct answer: Continue to the next exit and use a lawful route back.
Backing is prohibited on controlled-access highways, including shoulders. Never use a missed exit as a reason to back or turn across the median.

Why should you use the exit's deceleration lane before making the main reduction to ramp speed?
Correct answer: It lets you slow without disrupting the through-traffic flow.
Choose the exit lane in advance, signal and use the deceleration lane to reduce speed smoothly for the ramp.

A signed thru-turn intersection prohibits a direct left turn. What route does the handbook describe for completing that movement?
Correct answer: Go through, make the directed downstream U-turn, return and turn right.
A thru-turn relocates the left-turn movement. Follow the designated downstream U-turn and then return for a right turn instead of making a direct left.

You mistakenly exit a freeway at the single-point urban interchange described in the handbook. Can you simply drive straight across the intersecting highway and reenter on the other side?
Correct answer: No; turn onto the intersecting highway and find a safe lawful place to turn around.
The handbook explains that this interchange's exit does not provide that straight-across reentry movement. Follow its lane controls and use a lawful route to the correct entrance.

A diverging diamond interchange temporarily guides your lane onto the left side of the roadway. What should you do?
Correct answer: Follow the controlled lane path and signals through both crossovers.
A DDI intentionally transfers traffic to the left and then back to the right. Follow the signals, signs and lane guidance; do not improvise across islands.

The posted limit is 65 mph, but heavy rain has sharply reduced visibility and traction. What does Idaho's basic speed rule require?
Correct answer: A lower speed that is reasonable and prudent for the conditions.
A maximum limit does not replace judgment about visibility, surface conditions and hazards. Adjust speed so you can drive safely.

In a residential, business or urban district with no different posted limit, which maximum does the handbook state?
Correct answer: 35 mph.
The handbook states 35 mph unless otherwise posted. The basic rule still requires less when conditions make that necessary.

In ordinary good conditions, what minimum following interval does the handbook recommend behind another car?
Correct answer: At least three seconds.
Use a fixed roadside object to measure at least three seconds. This is a recommended minimum, not enough for every speed, vehicle or weather condition.

Rain becomes heavy while you follow another car at the usual minimum interval. What should change?
Correct answer: Increase the following interval substantially to provide an extra safety margin.
The handbook calls for increasing the three-second interval several times in bad weather. Reduced traction and visibility need more time and space.

A car follows you too closely. Which response helps reduce the risk?
Correct answer: Ease your speed safely and let the driver pass when possible.
Avoid escalation. The handbook advises slowing and allowing the close-following vehicle to pass, while preserving safe control and space.

You stop behind another vehicle. Which visual cue does the handbook recommend for a useful stopped gap?
Correct answer: Be able to see its rear tires where they touch the ground.
Seeing the rear tires at ground level helps leave room to maneuver around a stalled vehicle and may reduce a secondary impact if you are rear-ended.

Where should you direct part of your visual scan to anticipate developing hazards?
Correct answer: About ten to fifteen seconds ahead, while also checking sides and mirrors.
Look well ahead and keep the eyes moving. Early observation gives time to plan instead of making abrupt last-second decisions.

You are very upset after an argument and cannot concentrate. What is the safer choice?
Correct answer: Let someone else drive or wait until you can pay attention safely.
Strong emotions can interfere with attention and judgment. The handbook advises letting someone else drive when upset.

Your eyes feel heavy during a long highway drive. What should you do?
Correct answer: Leave the highway at a safe rest or service area and rest.
Stop driving when drowsy. A safe stop and rest address the danger; stimulants and temporary sensations are not reliable substitutes.

You will drive alone to an unfamiliar destination. What should you do before departure?
Correct answer: Learn or set up the route before driving so you do not need to handle navigation tasks in motion.
Prepare before moving. The handbook recommends knowing the route and using a passenger to help with navigation when one is available.

At night, what should your speed allow you to do?
Correct answer: Stop within the distance you can see ahead.
Nighttime sight distance is reduced. Do not overdrive the distance illuminated and visible ahead.

Oncoming headlights make it hard to see. What should you do with your gaze?
Correct answer: Avoid staring at them and look toward the lower right side of your traffic lane.
The handbook advises shifting your eyes down toward the lower right of your lane to reduce direct glare while maintaining awareness of the road.

Fog reduces daytime visibility to less than 500 feet. Which lighting and speed response is appropriate?
Correct answer: Use low-beam headlights and reduce speed.
Headlights are required when visibility is reduced to 500 feet or less. Low beams are best in these conditions; reduce speed and stop safely off the road if visibility becomes too poor.
