1. 1. After stopping for a flashing red indication, when may a driver proceed?

   1. Immediately, because flashing signals do not control traffic
   2. After yielding to cross traffic and pedestrians, when the way is clear
   3. Only after another driver waves the vehicle through
   4. Only when the signal changes to solid green
   Show answer

   After yielding to cross traffic and pedestrians, when the way is clear. A flashing red indication has the same stopping effect as a stop sign. The driver must stop completely, yield to cross traffic and pedestrians, and then proceed when the route is clear. The signal does not require waiting for green, but it also does not allow a rolling passage. Use the stop line or the appropriate stopping point, scan every conflicting movement, and continue only after yielding has been completed.

2. 2. In Idaho's fee table for a commercial driver's license (CDL), what does the skills test cost?

   1. $5 total
   2. $25 total
   3. It is free
   4. $10 to the county DMV plus up to $190 to the skills test examiner
   Show answer

   $10 to the county DMV plus up to $190 to the skills test examiner. Idaho's fee table for a commercial driver's license lists the skills test as $10 paid to the county DMV plus up to $190 paid to the skills test examiner, a total of up to $200. The Class D table lists a smaller skills test fee of $6.50 to the county plus up to $28.50 to the examiner. The knowledge test is $5, and all retest fees are the same as the original test fees, so the skills test is never free.

3. 3. What should you do if your vehicle begins to skid?

   1. Take your foot off the gas and steer in the direction of the skid
   2. Pump the brakes repeatedly while looking away from the roadway
   3. Accelerate sharply to force the rear wheels straight
   4. Turn opposite the skid and hold the brake down
   Show answer

   Take your foot off the gas and steer in the direction of the skid. During most skids, Idaho advises removing your foot from the accelerator and steering toward the direction the vehicle is sliding. That response helps the tires regain a usable path without adding sudden braking or acceleration. The other choices introduce abrupt control inputs that can deepen the slide or reduce the driver's ability to recover. Stay calm, look where you want the vehicle to go, and make the steering correction in the same direction as the skid.

4. 4. Which cars does Idaho's child safety seat law apply to?

   1. All cars regardless of year
   2. Only cars built after 2000
   3. Cars manufactured with safety belts after January 1, 1966
   4. Only cars with rear seats
   Show answer

   Cars manufactured with safety belts after January 1, 1966. Idaho law requires anyone carrying children 6 years of age or younger in a non commercial motor vehicle to protect them in approved child car safety seats, and the law applies to cars manufactured with safety belts after January 1, 1966. Proper protection means seats that meet federal safety standards, children fitted snugly with the seat's own straps, the seat secured to the vehicle, and the seat used on every trip.

5. 5. What should a driver expect when approaching an Idaho school zone sign?

   1. A railroad crossing with no special speed rule
   2. A school area with a crossing and increased penalties for violating the posted speed limit
   3. A truck-only loading area where pedestrians are prohibited
   4. A temporary construction lane controlled by orange signs
   Show answer

   A school area with a crossing and increased penalties for violating the posted speed limit. The school zone warning identifies a nearby school area and crossing, so the driver should watch for children and the marked crossing. Idaho also warns that violations of school zone speed limits carry increased penalties. The railroad and construction choices point to different warning categories, and the truck-only option ignores the child and pedestrian risk. When this sign appears, reduce distractions, search actively around the crossing, and obey the posted school-zone speed.

6. 6. What do orange signs, cones, drums, barricades, or flashing arrow panels commonly identify?

   1. A recreational scenic route
   2. A hospital service entrance
   3. A work zone
   4. A residential parking district
   Show answer

   A work zone. Idaho uses orange traffic-control devices to identify hazardous work areas shared by motorists and workers. These markers can signal uneven pavement, narrowed lanes, equipment, or other changes that require attention. The hospital, scenic-route, and parking choices describe unrelated locations and do not explain the cluster of orange devices. When the orange pattern appears, reduce distractions, follow every temporary instruction, and leave extra space rather than treating the area like ordinary roadway.

7. 7. What share of highway crashes does the Idaho handbook attribute to driver error?

   1. About 10 percent
   2. About half
   3. Less than 5 percent
   4. More than 90 percent
   Show answer

   More than 90 percent. Driver error causes more than 90 percent of highway crashes, so a driver must learn not only the rules but the mental and physical conditions that affect performance, including mood, fatigue and distraction. Your ability to drive safely depends on how you feel and what you were doing before you got behind the wheel, not just what you know, so fatigue, anger and distraction all belong in the risk calculation.

8. 8. What lane change should be anticipated at the pictured Lane Ends warning?

   
   1. A new lane will appear on the shoulder
   2. Two traffic lanes will soon become one
   3. All traffic must stop before the merge
   4. The right lane becomes a passing-only lane
   Show answer

   Two traffic lanes will soon become one. The Lane Ends warning indicates that two traffic lanes will soon become one lane. Drivers should identify the remaining lane, check surrounding traffic, signal, and merge when a safe gap is available. The sign does not add a shoulder lane, turn the lane into a passing-only facility, or automatically require every vehicle to stop. Merging traffic must yield where the handbook says so, making early awareness and a controlled lane change safer than waiting until the taper forces a sudden move.

9. 9. A driver age 21 or older is convicted of a second DUI within 10 years in Idaho. What license suspension applies?

   1. A mandatory one year suspension
   2. At least 90 days and up to 180 days
   3. A mandatory two year suspension
   4. A mandatory five year suspension
   Show answer

   A mandatory one year suspension. A second Idaho DUI conviction within 10 years brings a mandatory one year license suspension for an adult, along with mandatory jail of 10 days to one year and a fine of up to $2,000. The 90 to 180 day range belongs to a first conviction. Two years is the second offense suspension for a driver under 21. Five years is the upper end of the one to five year range for a third conviction.

10. 10. A driver passes you as you approach a curve and may not get back into lane safely. What should you do?

    1. Slow down and let the driver back into your lane quickly
    2. Brake sharply to make the driver back off
    3. Race ahead so the aggressive driver cannot pass
    4. Make eye contact and gesture to show that you object
    Show answer

    Slow down and let the driver back into your lane quickly. When another driver attempts a risky pass near a curve, hill, or oncoming vehicle, Idaho advises you to slow down and let that driver return to your lane quickly. Holding speed or accelerating can leave the passing driver trapped beside you, increasing the chance of a head-on crash. Braking hard can also surprise traffic behind you, so make room smoothly and keep control. The useful cue is the passing vehicle's limited path ahead: ease off, create an opening, and watch until the conflict has ended.

11. 11. What happens to an Idaho supervised instruction permit after a traffic-law conviction during the supervised period?

    1. Only the night-driving portion is suspended
    2. The permit is extended automatically
    3. The permit is canceled and the driver must reapply
    4. The driver may finish without any new application
    Show answer

    The permit is canceled and the driver must reapply. A conviction for violating traffic laws while operating under the supervised instruction period cancels the permit. The driver must apply for a new permit, and the minimum six months of supervised driving starts over when that new permit is issued. An automatic extension does not preserve the original progress, and the consequence is broader than a night-driving restriction. A practical reminder is that a violation resets both the credential and the supervised time clock.

12. 12. 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.

13. 13. A defensive driver should keep an eye on what is happening how far ahead?

    1. About 10 to 15 seconds ahead
    2. About 2 to 3 seconds ahead
    3. Only as far as the next intersection
    4. About 5 to 7 seconds ahead
    Show answer

    About 10 to 15 seconds ahead. Looking well ahead gives you time to notice a developing hazard and make a smooth decision before the last moment. The handbook uses a range of about 10 to 15 seconds, which is about a block in city driving. A glance only 2 to 3 seconds or 5 to 7 seconds ahead falls short of that range and leaves less time to react. Watching only the next intersection invites the last minute lane changes, turns, and stops that the handbook says often cause crashes. Keep your eyes moving beyond the vehicle directly ahead.

14. 14. What does the handbook QR code let a driver view online?

    1. A private school’s practice test only
    2. A county vehicle title application only
    3. The most up-to-date handbook
    4. A list of road closures for one day
    Show answer

    The most up-to-date handbook. The handbook directs readers to its QR code for the most up-to-date handbook online. That makes the current handbook the fact being tested. A county title application, a private school test, and a one-day road-closure list are unrelated services and are not identified by this instruction. When preparing for a knowledge test, use the linked handbook rather than relying on an old printed copy or an unofficial summary. The cue is the phrase most up-to-date, which points to the online edition itself.

15. 15. Can driving too slowly become a violation of Idaho's basic speed rule?

    1. Yes, but only when a police officer measures the speed
    2. No, only speeds above the limit can violate the rule
    3. No, slow driving is illegal only on interstates
    4. Yes, if the slow speed impedes the safe flow of traffic
    Show answer

    Yes, if the slow speed impedes the safe flow of traffic. Idaho's basic rule applies in both directions. A driver who goes so slowly that normal traffic is disrupted can violate the law even without exceeding a posted maximum. The interstate-only choice is too narrow, and a speed measurement is not the condition stated by the handbook. Keep right when appropriate, monitor the traffic you are affecting, and adjust for hazards without creating an unnecessary obstruction.

16. 16. What is the recommended action when a solid white line separates lanes moving in the same direction?

    1. Change lanes across it whenever the adjacent lane is empty
    2. Cross it immediately when traffic behind you is close
    3. Treat it as a centerline between opposing traffic
    4. Avoid changing lanes where a solid white line separates same-direction traffic
    Show answer

    Avoid changing lanes where a solid white line separates same-direction traffic. A solid white lane line separates traffic traveling the same way, and the handbook says to avoid changing lanes where one separates lanes moving in the same direction. It is not a yellow centerline, so the opposing direction choice misreads its purpose. An empty adjacent lane or a close vehicle behind you does not change that guidance. Where broken white lines separate lanes, the handbook says you may cross them when it is safe to change lanes. Check mirrors and turn your head to look before any lane change.

17. 17. What follows a second refusal of an evidentiary test within 10 years in Idaho?

    1. A 90 day suspension
    2. A two year absolute suspension
    3. A $250 fine only
    4. No additional penalty
    Show answer

    A two year absolute suspension. A first refusal brings a one year suspension with no driving privileges and a $250 civil penalty, and a second refusal within 10 years results in a two year absolute suspension, in addition to any court penalty for a DUI conviction. By comparison, a first failure of the test brings a 90 day suspension, so refusing costs more license time than failing the test.

18. 18. When you park parallel on an Idaho public road, how close to the curb or roadway edge must your vehicle be?

    1. Within 6 inches
    2. Within 24 inches
    3. Within 36 inches
    4. Within 18 inches
    Show answer

    Within 18 inches. Idaho requires a parallel parked vehicle to be within 18 inches of the curb or edge of the roadway and to face the same direction as traffic on that side. Six inches is closer than required but is not the stated limit. Twenty four and thirty six inches leave the car too far into the traffic lane. After parking, the handbook says to remove the keys and secure your car.

19. 19. What does the pictured round railroad warning sign tell a driver?

    
    1. It warns of a railroad crossing ahead
    2. It marks the exact rail where stopping is forbidden
    3. It identifies a bicycle route with no trains
    4. It announces that a roundabout is immediately ahead
    Show answer

    It warns of a railroad crossing ahead. The round yellow railroad symbol is an advance warning sign, so it tells the driver that a crossing lies ahead rather than marking the rails themselves. The handbook says to be prepared to stop before reaching the tracks if a train is approaching. Begin scanning, reduce speed as needed, and plan for the possibility of a stop. Do not confuse the circular design with a roundabout warning; the railroad letters and crossing symbol identify the hazard.

20. 20. When entering an Idaho roundabout, which traffic must you yield to?

    1. Only vehicles approaching from the right
    2. Pedestrians, bicyclists, and vehicles already circulating to your left
    3. Vehicles entering behind you
    4. No traffic because entering vehicles have priority
    Show answer

    Pedestrians, bicyclists, and vehicles already circulating to your left. Roundabout entry requires a driver to slow, obey signs and markings, and yield to pedestrians and bicyclists when entering or exiting. The driver must also yield to traffic already circulating on the left. The right-side choice reverses the roundabout's movement and can place the entering vehicle into an occupied circle. Reduce speed before the entry, look left for circulating traffic, and choose the gap that lets everyone continue without forcing a stop inside the circle.
