1. 1. Under Idaho law, who must wear a safety belt in a vehicle that came from the factory with belts?

   1. All occupants
   2. Only the driver
   3. Only people in the front seat
   4. Only passengers under 18
   Show answer

   All occupants. Idaho law requires all occupants to wear safety belts or shoulder straps in a vehicle equipped with them by the factory. The rule is not limited to the driver, the front seat, or minors. Young children also need approved child safety seats under the separate child restraint law. Belts reduce the chance of serious injury in a crash by about 50 percent.

2. 2. After a first failure administrative license suspension ends in Idaho, how long must an ignition interlock be installed on any vehicle the driver drives?

   1. 30 days
   2. One year
   3. 90 days
   4. Five years
   Show answer

   One year. After a first failure of an evidentiary test, the driver serves a 90 day suspension and then must have an ignition interlock on any vehicle driven for one year after the suspension ends. Thirty days is the no driving part of the suspension, and 90 days is the whole suspension, not the interlock period. Five years is the look back window for a second test failure. The driver pays the interlock installation and monthly fees.

3. 3. What is the safest response when a pedestrian unexpectedly enters the roadway?

   1. Sound the horn and steer toward the pedestrian to claim the lane
   2. Maintain speed because pedestrians must always yield outside a marked crosswalk
   3. Use extreme caution, reduce speed, and be prepared to stop
   4. Pass a stopped vehicle that is yielding in the adjacent lane
   Show answer

   Use extreme caution, reduce speed, and be prepared to stop. Idaho emphasizes that pedestrians can appear unexpectedly and that a driver must use extreme caution in areas where they may be present. Slowing and preparing to stop gives the driver time to protect a person who enters the roadway. The marked-crosswalk choice is too broad because the handbook describes situations requiring a stop even where no painted crosswalk exists. A horn or an adjacent-lane pass can startle people or hide them from view. Scan beyond the immediate lane and cover the brake.

4. 4. What does Idaho require when approaching a stopped emergency vehicle with flashing lights on a two-lane road?

   1. Reduce speed below the posted limit and proceed with caution
   2. Maintain the posted speed and pass closely
   3. Stop permanently until the vehicle is removed
   4. Turn around before reaching the emergency vehicle
   Show answer

   Reduce speed below the posted limit and proceed with caution. When a stopped emergency or police vehicle displays flashing lights, Idaho requires approaching drivers to immediately reduce speed below the posted limit and proceed with caution. The lane-change requirement applies when there are two or more lanes in the same direction, so on a two-lane road the central duty is slowing and careful passage. Normal speed leaves responders less protection, while stopping permanently or turning around is not the stated response. Scan for people and equipment near the roadway.

5. 5. After stopping at a steady red light, when may a driver generally turn right?

   1. After yielding to cross-traffic, unless a sign prohibits the turn
   2. Whenever the driver has waited at least five seconds
   3. Before stopping, if no pedestrian is visible
   4. Only when a green arrow appears, even if no restriction is posted
   Show answer

   After yielding to cross-traffic, unless a sign prohibits the turn. Idaho permits a right turn at a steady red light after the driver stops and yields to cross-traffic, unless the location is posted otherwise. The stop is a prerequisite, not an optional courtesy, and the driver must still check pedestrians and other road users before moving. A timed wait does not create permission, and an empty-looking crosswalk does not justify rolling through the red. Look for a no-turn-on-red sign, stop behind the line, yield, and turn only when the path is clear.

6. 6. At an unmarked three-way T intersection, what must a driver do before turning onto the cross street?

   
   1. Yield only to vehicles approaching from the right
   2. Stop and yield to drivers approaching from the other two directions
   3. Continue if the nearest lane appears empty
   4. Stop only when a warning sign is posted
   Show answer

   Stop and yield to drivers approaching from the other two directions. At a T intersection, the road ending at the cross street does not carry a driver through by default. Idaho requires the driver who must turn right or left to stop and or yield to traffic approaching from the other two directions. The choice “Yield only to vehicles approaching from the right” narrows the duty to one side and can expose the vehicle to cross traffic from the other side. Treat the end of your roadway as a full conflict point and check both directions before entering.

7. 7. What should a driver do in a designated work zone with a posted reduced speed limit?

   1. Follow the vehicle ahead instead of the sign
   2. Use the normal highway limit unless workers enter the lane
   3. Slow only when a flagger is visible
   4. Observe the posted work zone limit
   Show answer

   Observe the posted work zone limit. The work-zone limit applies where it is posted, and Idaho warns that violating it can bring an enhanced, fixed penalty. The driver does not get to wait until workers enter the lane or substitute the normal highway limit. The vehicle ahead may be traveling unlawfully, so following it is not a safe legal standard. Spot the work-zone signs early, reduce speed before the activity area, and maintain attention around workers and changing lanes.

8. 8. At a four-way stop, which vehicle goes first when it arrived noticeably before the others?

   
   1. The first vehicle to arrive
   2. The vehicle on the right even if it arrived later
   3. The vehicle going straight
   4. The largest vehicle
   Show answer

   The first vehicle to arrive. At a four-way stop, Idaho gives priority to the first vehicle that arrives. The right-side rule becomes important when two vehicles arrive at the same time, not when one vehicle clearly got there first. The straight-ahead and largest-vehicle choices have no general priority under this rule. Approach every stop fully, note the order of arrival, and proceed only after yielding to any vehicle that reached the intersection earlier.

9. 9. How long after moving to Idaho must a new resident apply for an Idaho driver's license?

   1. Within 60 days of moving household goods
   2. Within 10 days of signing a lease
   3. Within 30 days of residing in Idaho
   4. By the next license renewal date
   Show answer

   Within 30 days of residing in Idaho. A person who moves to Idaho must apply for an Idaho driver's license within 30 days of residing there. The deadline is tied to residence, not to signing a lease, transporting belongings, or the expiration of an out-of-state credential. The handbook expressly says the rule applies whether the other license has expired or not. A new resident should treat the 30-day period as the planning window for the county licensing process and required documents.

10. 10. What movement is forbidden by the pictured Do Not Enter sign?

    
    1. Leaving the roadway at the next exit
    2. Entering that section from your direction of travel
    3. Turning into a marked parking space
    4. Passing a slower vehicle on the left
    Show answer

    Entering that section from your direction of travel. The Do Not Enter sign bars entry into that section of highway from the direction the driver is traveling. It is not merely a parking restriction, a warning about a dead end, or a command to avoid passing. Such signs commonly protect the wrong approach to a one-way segment or ramp. The practical cue is the direction of your intended movement: if the sign faces you at the entrance, find another lawful route rather than crossing the sign.

11. 11. At what age can an Idaho applicant get a Class D Instruction Permit without a parent or guardian signing as the liability signer?

    1. 18
    2. 16
    3. 17
    4. 21
    Show answer

    18. Every Idaho applicant under 18 needs a parent or guardian with verifiable custody to sign as the liability signer and take on the applicant's obligation. At 18 the applicant may apply for a Class D Instruction Permit without that signature. Sixteen and seventeen year olds are still under 18, so they still need the signer. Twenty one is the age tied to the Under 21 license marking and the GDL supervisor, not to the liability signer.

12. 12. What does an Idaho yield sign require when a driver approaches an intersection or highway?

    
    1. Accelerate to enter before other traffic
    2. Slow down and yield to vehicles and pedestrians
    3. Stop every time even when the way is clear
    4. Yield only to vehicles, never to pedestrians
    Show answer

    Slow down and yield to vehicles and pedestrians. A yield sign requires a driver to slow down and give the right-of-way to vehicles and pedestrians in the intersection being crossed or the highway being entered. A complete stop may be necessary when traffic or people make it unsafe to continue, but stopping every time is broader than the sign’s basic instruction. Accelerating defeats the purpose of yielding, and pedestrians are expressly included. Approach with enough control to stop if needed, scan both directions, and proceed only after the crossing path is clear.

13. 13. How quickly can a small stream become dangerous in an Idaho flash flood, according to the handbook?

    1. It takes hours to rise
    2. It rarely exceeds 6 inches
    3. It can swell to over 12 inches deep and 80 feet wide in less than five minutes
    4. Streams do not flood in Idaho
    Show answer

    It can swell to over 12 inches deep and 80 feet wide in less than five minutes. Flash floods follow intense rain in a short time, often during or right after a severe thunderstorm, and small streams a few feet wide and a few inches deep can swell to over 12 inches deep and 80 feet wide in less than five minutes. Six inches of fast water can knock you down, and two feet can wash a vehicle away, so never drive into flooded roads.

14. 14. How far does a loaded truck at 55 mph need to stop on a dry road, according to the Idaho handbook?

    1. 100 feet
    2. 450 feet with properly adjusted brakes
    3. 200 feet
    4. 1,000 feet
    Show answer

    450 feet with properly adjusted brakes. It takes a loaded truck with properly adjusted brakes 450 feet to come to a complete stop when traveling 55 miles per hour on a dry road, so allow extra space for large vehicles to speed up or stop, never cut in front of one, and remember that sharp turns may require the truck to use more than one lane.

15. 15. How should a driver respond to a flashing circular yellow traffic signal?

    1. Treat the signal as a steady red light
    2. Stop completely and wait for a green arrow
    3. Accelerate because the signal gives protected movement
    4. Slow down, look carefully for hazards, and proceed cautiously
    Show answer

    Slow down, look carefully for hazards, and proceed cautiously. A flashing circular yellow signal calls for caution, not an automatic stop and not protected passage. Slow down, look carefully for hazards, and proceed only when the movement is safe. A steady red response would add a stop requirement that this signal does not impose, while acceleration reduces the time available to notice cross traffic or pedestrians. A green arrow is a different indication with a different meaning. Approach the signal with reduced speed and actively scan the conflict areas before continuing.

16. 16. What insurance proof is required in the vehicle for an Idaho skills test?

    1. An SR22 certificate
    2. A verbal assurance
    3. Nothing, the examiner's insurance applies
    4. A paper or digital copy of valid proof of insurance; an SR22 is not valid proof
    Show answer

    A paper or digital copy of valid proof of insurance; an SR22 is not valid proof. A paper or digital copy of valid, unexpired proof of insurance must be in the vehicle during the skills test, and an SR22 is not valid proof of insurance. The registration must also be present, valid and signed, not a photocopy. Rental cars may not be used for a skills test by an unlicensed applicant or anyone under 25, and dealer plates need a dealer ID.

17. 17. What shape and color identify most warning signs in Idaho?

    1. Black lettering on white rectangles
    2. White lettering on green rectangles
    3. Black symbols or lettering on yellow, usually diamond-shaped
    4. Blue symbols on circular signs
    Show answer

    Black symbols or lettering on yellow, usually diamond-shaped. Most Idaho warning signs use black on yellow and a diamond shape. This visual combination alerts drivers that an unexpected condition may be ahead, so they should look for the hazard and prepare to slow or take another safe action. Green rectangles normally provide guide information, white regulatory signs communicate rules, and blue signs commonly identify services. The diamond is the quick recognition cue. Read the symbol or wording next, then adjust speed before reaching the condition described.

18. 18. Is beer safer than hard liquor, according to the Idaho handbook?

    1. Yes, beer has far less alcohol
    2. Yes, wine is the only strong drink
    3. No, a 1.5 ounce jigger of liquor, five ounces of wine and 12 ounces of beer each contain about an ounce of alcohol
    4. Only light beer is safer
    Show answer

    No, a 1.5 ounce jigger of liquor, five ounces of wine and 12 ounces of beer each contain about an ounce of alcohol. A jigger, 1.5 ounces, of 80 proof hard liquor, five ounces of table wine, or 12 ounces of beer all contain approximately the same amount of alcohol, about an ounce each, and studies found the greatest share of people arrested for DUI had been drinking beer. Alcohol passes directly into the blood, and only time removes it, so the container does not matter.

19. 19. Which category is explicitly listed among Idaho's traffic sign types?

    1. Warning signs
    2. All of these categories
    3. Work zone signs
    4. Guide signs
    Show answer

    All of these categories. The handbook lists regulatory, warning, work zone, guide, and other signs as traffic sign types, so every category named in the choices “Warning signs”, “Guide signs” and “Work zone signs” belongs on that list. The broader answer captures the full set presented by the question. A warning sign concerns an unexpected condition, a guide sign supplies travel or service information, and a work zone sign marks road work conditions. Learn each category by its colors, shapes, messages, and symbols so you can identify its purpose before reaching it.

20. 20. What does a double solid yellow centerline allow?

    1. Passing is allowed across the lines whenever visibility is good
    2. Crossing is allowed to merge into the opposite lane before a turn
    3. Passing a slow vehicle is allowed if the driver signals first
    4. Crossing is allowed for a safe left turn into or out of a driveway or business entrance
    Show answer

    Crossing is allowed for a safe left turn into or out of a driveway or business entrance. Two solid yellow lines mark a no-passing condition for both directions. The limited crossing described in the handbook is for a left turn into or out of a driveway or business entrance, and it must be safe. A clear view does not make ordinary passing legal, and a slow truck is not an exception. Driving along the paint to set up a U-turn is not authorized by this marking. Use the centerline as a boundary, then wait for a lawful turning opportunity rather than treating it as a passing gap.
