1. 1. A large vehicle angles left before turning right. What should you avoid?

   1. Waiting behind until the turn finishes
   2. Squeezing past on its right side
   3. Leaving extra room beside the trailer
   4. Watching for the trailer wheels tracking inward
   Show answer

   Squeezing past on its right side. Large vehicles may angle into the left lane to make a right turn without climbing the curb. Squeezing by on the right puts your vehicle where the trailer will sweep, a frequent cause of crashes with large vehicles. Picking "Waiting behind until the turn finishes" would make waiting the error, while patience behind the truck keeps you clear of its turning path. When a truck swings wide, hold your position and let the trailer complete its arc before proceeding.

2. 2. How long may a person age 17 or older practice on an Idaho Class D Instruction Permit?

   1. For six months while practice hours are logged
   2. Until the eighteenth birthday of the holder
   3. For one year while an adult supervisor rides along
   4. For two years without any renewal or retest
   Show answer

   For one year while an adult supervisor rides along. The Class D Instruction Permit serves applicants who are 17 or older. It allows practice for one year with an adult who holds a valid license riding along, after the applicant passes the knowledge test. The six month figure belongs to other permit stages, not this practice window. Picking "For six months while practice hours are logged" would cut the year in half and confuse this permit with supervised teen stages. Calendar the full year, and practice regularly instead of cramming drives near expiration.

3. 3. In daytime fog, after turning on headlights, what beam setting is required first?

   1. Set high beams to see through the fog
   2. Use parking lights until fog thickens
   3. Adjust them to low beams when first turned on
   4. Alternate beams every few seconds
   Show answer

   Adjust them to low beams when first turned on. Fog, smoke, dust, and heavy rain call for headlights set to low beam when first turned on. High beams reflect off the particles in front of you and can shrink the distance you can actually see. Picking "Set high beams to see through the fog" would aim brighter light into the fog bank, where reflection creates glare instead of a clearer view. As visibility falls, click to low beam and slow down while the road edges come back into view.

4. 4. Unless another limit is posted, what is the maximum speed in an Idaho residential, business, or urban district?

   1. 25 mph
   2. 35 mph
   3. 30 mph
   4. 45 mph
   Show answer

   35 mph. Idaho sets the maximum speed in any residential, business, or urban district at 35 miles per hour unless a different limit is posted. Twenty five and thirty miles per hour are lower than the Idaho default for these districts. Forty five is faster than the Idaho default. The basic rule still applies, so conditions may require driving slower than 35.

5. 5. How many points can a Traffic Safety Course remove at most?

   1. A maximum of three points from the record
   2. All points regardless of the total amount
   3. A maximum of four points from the record
   4. A maximum of eight points from the record
   Show answer

   A maximum of four points from the record. Completing a Traffic Safety Course can remove a maximum of four points from an Idaho driving record. That is one more than the three point limit attached to the separate defensive driving course option. Picking "A maximum of three points from the record" would apply the three point defensive driving limit to a course Idaho caps at four points. Match the course name to its cap before counting how much relief a record will actually receive.

6. 6. Can an Idaho driver below .08 BAC still be convicted of driving under the influence?

   1. Yes, if other intoxicating substances impair the driver
   2. No, because .08 is required for every conviction
   3. Yes, but only when the driver is under age 21
   4. No, unless the driver also refuses a chemical test
   Show answer

   Yes, if other intoxicating substances impair the driver. The .08 figure is the alcohol concentration limit for adults, not a shield against every impaired driving charge. A driver under that reading may still be convicted when other intoxicating substances impair driving. Youth and commercial thresholds are lower still, at .02 and .04. Picking "No, because .08 is required for every conviction" would treat one alcohol number as the only path to a conviction. Officers look at impairment itself, so a low breath reading does not end the inquiry.

7. 7. Before driving, ice and snow must be cleaned from what?

   1. Only the front windshield center section
   2. The roof but never the side windows
   3. All windows for full visibility
   4. The hood so snow cannot slide down
   Show answer

   All windows for full visibility. Windows must be cleaned of ice, snow, and dirt before driving to ensure maximum visibility in all directions. A single cleared stripe forward hides cross traffic, pedestrians, and lane changes on both sides. Picking "Only the front windshield center section" would accept a center stripe view while side windows stay blind for turns and merges. Scrape every window fully and knock roof snow loose so braking does not dump it forward.

8. 8. Why are freeways usually safer than other kinds of roads?

   1. One way traffic and limited entrances
   2. Higher speeds reduce driver fatigue greatly
   3. Traffic lights control every merging movement
   4. Shoulders are wider than all other roads
   Show answer

   One way traffic and limited entrances. Freeways, interstates, and expressways are usually safer because traffic moves one way, entrances are limited, and special safety features separate opposing flows. At freeway speeds, though, a single error can still be disastrous. Picking "Higher speeds reduce driver fatigue greatly" would credit higher speed itself, while speed is the danger the design features work against. Enjoy the separation freeways give you, but keep scanning because closing speeds stay unforgiving.

9. 9. Using a motor vehicle to commit a felony can lead Idaho to do what?

   1. Suspend or revoke the license of the driver
   2. Send a warning letter with no further action
   3. Remove points from the record of the driver
   4. Require a vision test at the next renewal
   Show answer

   Suspend or revoke the license of the driver. Idaho lists a felony committed with a motor vehicle among violations for which the courts or Idaho Transportation Department may suspend, disqualify, deny, cancel, or revoke a driver's license. That is why the license consequence in this item is suspension or revocation. A warning letter is not the listed consequence for this felony violation; the handbook separately describes warning letters in its point system and graduated-driver penalties. Removing points would not address the license sanction described for this offense, and a vision test at renewal is unrelated to it. A conviction for this violation puts the driver's license privilege at risk.

10. 10. Approaching a yield sign, what must you always be ready to do?

    1. Maintain speed unless a horn sounds behind
    2. Slow down and be prepared to stop
    3. Stop fully in every case no matter what
    4. Accelerate to claim the gap before others
    Show answer

    Slow down and be prepared to stop. A yield sign requires slowing down and being prepared to stop for traffic that has the right of way. The stop itself is conditional, but the readiness to stop is required on every approach. Maintaining speed unless a horn sounds would keep full pace toward traffic that may already own the intersection. Cover the brake at every yield sign and decide early whether rolling through is truly safe.

11. 11. When may the Bicycles May Use Full Lane sign be used on an Idaho road?

    1. Where a separate bike lane is provided
    2. Only at intersections with traffic signals
    3. With shared lane markings or instead of them
    4. On roads closed to motor vehicles
    Show answer

    With shared lane markings or instead of them. Shared lane markings, called sharrows, show where people should preferably cycle in a travel lane. The Bicycles May Use Full Lane sign can support those markings or stand in their place. Picking "Where a separate bike lane is provided" would miss the point, since full lane signs serve lanes that riders share with cars. Seeing either device, expect a bicyclist positioned in the lane, pass with full clearance, and never squeeze alongside in the same lane.

12. 12. Why should you never honk while close to a bicyclist?

    1. The horn may startle the rider into a swerve
    2. The horn cannot be heard by bicycle riders
    3. Honking near riders is a moving violation
    4. Riders may think you want them to speed up
    Show answer

    The horn may startle the rider into a swerve. A loud horn beside a bicyclist can startle the rider into an unexpected reaction, including a swerve into traffic. Communication with riders works better through patience, space, and predictable vehicle movement at a distance. Picking "The horn cannot be heard by bicycle riders" would say riders cannot hear a horn, yet the danger is precisely that a close rider hears it suddenly. If a rider has not noticed you, hold back, widen the gap, and pass quietly when the road opens.

13. 13. When you park facing downhill on an Idaho street with a curb, which way should the front wheels point?

    1. Sharply toward and against the curb
    2. Sharply away from the curb
    3. Straight ahead within the marked parking lane
    4. Toward the center of the road
    Show answer

    Sharply toward and against the curb. Facing downhill, turn the front wheels sharply toward and against the curb. If the vehicle rolls, the curb blocks the tire instead of letting the car travel into the traffic lane. The away-from-curb direction is the uphill setting, so it reverses the condition. Wheels left straight ahead or aimed at the center line give the car a path into moving traffic. Set the parking brake and leave the transmission in the proper position as well, then check that the tire is actually resting against the curb.

14. 14. A traffic light is dark because of a power outage. How do you proceed?

    1. Treat your green direction as still active
    2. Yield as you would at a four way stop
    3. Drive through slowly without stopping fully
    4. Follow only the directions of other drivers
    Show answer

    Yield as you would at a four way stop. A signal knocked out by a power outage works like a four way stop. Every approach yields in the same manner, taking turns by arrival order rather than assuming a former green still applies. Picking "Treat your green direction as still active" would extend your old green phase indefinitely while cross drivers face the same dark signal. Roll up to a dead signal expecting a full stop and eye contact with drivers on every other approach.

15. 15. How far before your exit should you move into the lane nearest it?

    1. About a half mile before the exit
    2. About two miles before the exit ramp
    3. Only after you pass the exit sign
    4. In the last hundred feet before the ramp
    Show answer

    About a half mile before the exit. Planning a freeway exit starts about a half mile ahead. Signaling and moving into the lane nearest the exit at that distance avoids late lane changes across faster traffic near the ramp entrance. Picking "About two miles before the exit ramp" would keep you far from the exit lane for most of the approach and then demand several hurried lane changes at once. When the half mile exit sign appears, start your signal, check mirrors and blind spots, and drift toward the exit side.

16. 16. When may an Idaho bicyclist ride away from the right-hand curb or edge of the road?

    1. When riding beside another bicyclist
    2. When traveling downhill on a highway
    3. Only when no motor vehicle is approaching
    4. When passing, turning left, or avoiding an obstacle
    Show answer

    When passing, turning left, or avoiding an obstacle. Bicyclists ride with traffic and stay as close to the right curb or edge as safety allows. That position changes when the rider is passing, turning left, or avoiding an obstacle, and when the road is too narrow to share side by side. Picking "Only when no motor vehicle is approaching" would tie the position to traffic gaps rather than the maneuver underway. Drivers should expect a rider to move left for a turn or around debris, then give room.

17. 17. An intersection has a left-turn-only lane beside a lane marked for left turns or straight travel. What must drivers in the left lane do?

    1. They may continue straight through the intersection.
    2. They may choose either left or straight travel.
    3. They must stop and wait for the right lane to turn.
    4. They must turn left from that lane.
    Show answer

    They must turn left from that lane.. The left lane in this marked two-lane arrangement is reserved for left turns. Drivers in that lane must turn left, while the adjacent right lane may turn left or continue straight as its markings permit. Straight travel is not allowed from the left-turn-only lane, and that lane does not gain the right lane's options. The pavement marking also does not require waiting for the adjacent lane to turn first. Follow the arrow for the lane your vehicle occupies rather than borrowing the movement marked for the next lane.

18. 18. Which foreign drivers are exempt from the Idaho knowledge test?

    1. Drivers from Germany are exempt from it
    2. No foreign drivers are exempt from it
    3. Drivers from Korea are exempt from it
    4. Drivers from Canada are exempt from it
    Show answer

    No foreign drivers are exempt from it. Country rules change which parts of licensing a foreign driver can skip, but the knowledge test is never one of them. German drivers skip surrender and the skills test, and Korean or Taiwanese drivers who keep their license must take the skills test, yet every foreign driver must still pass the knowledge test. Study the Idaho handbook before your appointment no matter which country issued your current license.

19. 19. What fact explains the handbook's instruction to back slowly?

    1. Backing gives the driver a wider view
    2. Backing makes the vehicle easier to control
    3. Reverse gear increases the vehicle's speed
    4. Backing makes the vehicle harder to control
    Show answer

    Backing makes the vehicle harder to control. The handbook tells drivers to back slowly because a vehicle is more difficult to control while backing. That is the reason behind the slower movement, not a claim about reverse gear being faster than first gear. Backing also does not give a wider view; the same section says not to rely on mirrors and to look through the rear window. Saying that control becomes easier reverses the handbook's warning. Reduced control during backing calls for slow movement and continued looking back.

20. 20. When are wet roads often most slippery for Idaho drivers?

    1. After several days of steady rainfall
    2. Only when standing water covers the road
    3. After crews have sanded the wet surface
    4. At the start of light rain when oil mixes with water
    Show answer

    At the start of light rain when oil mixes with water. Wet pavement demands slower speeds and longer stopping room at any point in a storm. The slickest moment often comes early, at the start of light rain, when road oil and water mix into a greasy film. Tires that grip well at lower wet speeds can lose contact as speed climbs. Picking "After several days of steady rainfall" would place the worst grip late, after oil has washed away. Ease off speed as the first rain lands, before the road looks fully soaked.
