1. 1. When adjusting driving position, where should the top of the steering wheel sit in Tennessee guidance?

   1. No higher than the top of the shoulders
   2. At chin level for a clearer view
   3. Above the shoulders so arms reach upward
   4. Steering wheel height is never adjusted
   Show answer

   No higher than the top of the shoulders. The manual says the top of the steering wheel should be no higher than the top of the shoulders. Adjust the seat and, if equipped, the steering column for proper driving posture. The seat should be upright, the pedals easily reached, and the body about 10 to 12 inches from the steering wheel. Adjust mirrors after adjusting the seat. Chin level is too high; the wheel top should stay at or below the shoulders.

2. 2. How often are Tennessee interstate emergency reference markers installed along heavily traveled urban sections?

   1. Every mile
   2. Every 1,000 feet
   3. Every five miles
   4. Only at interchanges
   Show answer

   Every 1,000 feet. Emergency reference markers are installed every 1,000 feet along heavily traveled urban interstate sections in Nashville, Knoxville, Memphis, Jackson, and Chattanooga. They show the route, direction of travel, and log mile in tenths so motorists can report where assistance is needed. The stated spacing is every 1,000 feet, not every mile. The markers are installed every 1,000 feet, not every five miles.

3. 3. Tennessee's list of no parking areas bars a vehicle from stopping within what distance of a crosswalk?

   1. Within 20 feet of a crosswalk is prohibited
   2. Within 5 feet of a crosswalk
   3. Within 10 feet of a crosswalk
   4. Parking at the crosswalk edge is allowed at night
   Show answer

   Within 20 feet of a crosswalk is prohibited. Parking is prohibited within 20 feet of a crosswalk or in the marked crosswalk area. Five feet is less than the required 20-foot clearance. Ten feet is less than the required 20-foot clearance. Darkness creates no parking exception. The manual passage behind this item states: "• Within 20 feet of a crosswalk or in the crosswalk marked area" Before leaving the vehicle, check that the full twenty foot gap before the crosswalk remains open and unblocked.

4. 4. A blind pedestrian with a white cane or guide dog is crossing away from a crosswalk. What must the driver do?

   1. Honk once to announce the vehicle
   2. Stop at least 10 feet away until the person is off the roadway, without using the horn
   3. Proceed slowly around the pedestrian at 5 mph
   4. Flash headlights so the pedestrian can sense the car
   Show answer

   Stop at least 10 feet away until the person is off the roadway, without using the horn. When a blind or visually impaired pedestrian with a guide dog or a white cane, including one with a red tip, crosses any part of the roadway, stop at least 10 feet away until the person is off the roadway. Do not use the horn because it could startle the pedestrian. The manual also covers a hearing-impaired person with a dog on a blaze orange leash.

5. 5. During peak HOV hours, which combination of travelers may use the reserved Tennessee HOV lane?

   1. Only buses, regardless of occupancy
   2. Solo drivers in electric vehicles only
   3. Vehicles with two or more persons, buses with 2 or more occupants, motorcycles with 1 person, and emergency vehicles
   4. Any vehicle during the first hour of operation
   Show answer

   Vehicles with two or more persons, buses with 2 or more occupants, motorcycles with 1 person, and emergency vehicles. During peak HOV hours, eligible traffic includes vehicles with two or more persons, buses with two or more occupants, motorcycles with one person, and emergency vehicles. A baby in a car seat counts as a passenger. Buses share the lane with carpools and motorcycles. The manual lists carpools, qualifying buses, motorcycles, and emergency vehicles; access is not limited to solo electric-vehicle drivers.

6. 6. If you drive at a speed below the flow of traffic on the interstate, which lane must you use?

   1. The right lane
   2. Either lane, provided you stay consistent
   3. The shoulder during heavy congestion
   4. The left lane, with hazard lights flashing
   Show answer

   The right lane. If you drive below the flow of traffic on the interstate, you must use the right lane. The shoulder is not an ordinary travel lane; the manual allows its use for marked deceleration or an emergency. The manual requires slower traffic to use the right lane. Consistency in the wrong lane fails. Use the right lane. Shoulder travel is allowed only for marked deceleration or an emergency.

7. 7. At which rural or urban location is a U-turn prohibited based on sight distance?

   1. Where traffic can be seen for 600 feet in each direction
   2. Where any other vehicle is within one mile
   3. Where you cannot see traffic coming from both directions for at least 500 feet in each direction
   4. Where the road has two lanes only
   Show answer

   Where you cannot see traffic coming from both directions for at least 500 feet in each direction. Do not make a U-turn where you cannot see traffic coming from both directions for at least 500 feet in each direction. Other restrictions also apply, including bans at intersections controlled by a traffic light or officer, between city intersections, and where official signs or markings prohibit U-turns. Seeing traffic for 600 feet in each direction exceeds the 500-foot sight-distance requirement, although other U-turn restrictions still apply.

8. 8. What does Tennessee law expect regarding litter thrown from a vehicle?

   1. Littering is allowed on rural roads only
   2. Drivers must not litter and can face penalties for trash thrown from vehicles
   3. Only glass bottles count as litter
   4. Passengers may litter if the driver objects
   Show answer

   Drivers must not litter and can face penalties for trash thrown from vehicles. Throwing cigarette butts, food sacks, tobacco products, papers, cans, bottles, or other material from vehicles is littering. The manual says littering violates state law, with fines from $50 to $3,000 based on the amount of litter. Rural roads receive no littering exemption. Paper and other debris also count as litter. A driver objection does not authorize passenger littering. The manual passage behind this item states: "Littering is against state law. Fines start at $50 and can be up to $3,000 based upon the amount of litter"

9. 9. Which time gap does the manual associate with maintaining following distance in normal conditions?

   1. Half a second
   2. One second
   3. Ten seconds
   4. Two seconds
   Show answer

   Two seconds. Use a stationary roadside point to check that you are following no closer than two seconds on state and U.S. highways with moderate speed limits. The manual calls for increasing the gap to at least four seconds in inclement weather, at higher interstate speeds, at night, and when following a motorcycle. Half a second is less than the manual’s two-second following interval.

10. 10. On a roadway with at least two lanes traveling in your direction, what does Tennessee’s Move Over law require when approaching a stationary emergency vehicle with flashing lights along your side of the road?

    1. Move to a lane away from the stopped vehicle or slow down when moving is unsafe
    2. Speed up to clear the scene quickly
    3. Stop in the travel lane beside it
    4. Flash headlights and continue at full speed
    Show answer

    Move to a lane away from the stopped vehicle or slow down when moving is unsafe. When safety and traffic conditions permit, move into a lane not adjacent to the stopped emergency vehicle. If changing lanes would be impossible or unsafe, proceed cautiously, reduce speed, and maintain a safe speed for road conditions. Speeding past raises risk for responders on foot. The manual directs you to move over safely or proceed cautiously at a reduced speed. Headlight flashes do not replace moving over or slowing.

11. 11. How much unrestricted driving experience must a For-Hire endorsement applicant have?

    1. 6 months of unrestricted experience
    2. 1 year of unrestricted experience
    3. 2 years of unrestricted experience
    4. 5 years of unrestricted experience
    Show answer

    2 years of unrestricted experience. A For-Hire endorsement applicant must have two years of unrestricted driving experience. The manual also requires applicants to meet the endorsement’s other eligibility conditions, pass the appropriate tests, and pay the fee. Six months is less than the two years of unrestricted driving experience required for a For-Hire endorsement. One year still falls short of the requirement. Five years exceeds what the rule demands.

12. 12. Your vehicle is disabled on a Tennessee interstate and it is not an extreme emergency. What does the manual advise?

    1. Walk along the shoulder to the nearest exit
    2. Cross the lanes on foot to find a phone
    3. Stand in the median to wave down traffic
    4. Stay in your vehicle until a State Trooper, other police officer, emergency service vehicle or a good Samaritan stops to offer assistance
    Show answer

    Stay in your vehicle until a State Trooper, other police officer, emergency service vehicle or a good Samaritan stops to offer assistance. The manual says walking on the interstate is both illegal and dangerous. Except in extreme emergencies, you should remain in your disabled vehicle until a State Trooper, other police officer, emergency service vehicle or a good Samaritan stops to offer assistance. Walking the shoulder, crossing lanes or standing in the median all expose you to fast traffic. A stopped car on the interstate, even on the shoulder, is extremely dangerous, so the manual says not to stop there except for an emergency.

13. 13. About how often should a driver check traffic behind with the rearview mirror, in Tennessee guidance?

    1. Only when changing lanes
    2. About every 10 seconds
    3. About once every five minutes
    4. Only on interstate highways
    Show answer

    About every 10 seconds. Use the rearview mirror to check traffic behind frequently, about every 10 seconds. This can alert you to a vehicle approaching too quickly or tailgating. Also check behind when changing lanes, backing up, slowing down quickly, or driving down a long steep hill. Keep the look behind brief. The manual advises frequent checks, about every 10 seconds, as well as checks when changing lanes.

14. 14. A Tennessee child is six years old, weighs more than 20 pounds, and is four feet five inches tall. What restraint is required?

    1. A belt positioning booster seat system while wearing a seatbelt
    2. A rear facing car seat
    3. A forward facing car seat only
    4. The vehicle belt alone, because the child is over age five
    Show answer

    A belt positioning booster seat system while wearing a seatbelt. A six-year-old who is four feet five inches tall is within the manual’s booster category: ages four through eight and shorter than four feet nine inches. The child must use a belt-positioning booster seat system and wear a seatbelt. The manual also says children in booster seats must ride in the back seat if the vehicle has one. Rear facing seats are for children under one year or under 20 pounds.

15. 15. A lane shows both a turn arrow and a straight arrow. What may you do from it?

    1. Turn only; the straight arrow is decorative
    2. Use it for parking when traffic is heavy
    3. Proceed straight or make the indicated turn
    4. Turn either direction regardless of the arrow
    Show answer

    Proceed straight or make the indicated turn. Dual use lanes authorize either movement printed on the pavement: continue straight through or complete the turn the arrow describes, following signs at the intersection as well. The straight arrow carries real meaning rather than decoration, and heavy traffic never converts a travel lane into parking. Turning against the arrow's direction violates the lane assignment. Without a protected arrow, standard right of way rules still govern your turn, so yield as you would from any ordinary lane.

16. 16. Stopped behind another vehicle at an intersection, what visual check confirms an adequate gap?

    1. You can read the other driver's mirror reflection
    2. Your hood aligns with the vehicle ahead's bumper
    3. You can see the license plate and/or rear tire where it meets the pavement
    4. You can see over the roof of the vehicle ahead
    Show answer

    You can see the license plate and/or rear tire where it meets the pavement. Leave enough space to see its license plate and/or its back tire where it meets the pavement. This provides room if the vehicle rolls back slightly or stalls, and can provide an escape path if a vehicle approaches too fast from behind. Mirror reflections do not measure the gap. The manual’s visual check is seeing the license plate and/or the rear tire where it meets the pavement.

17. 17. What must an applicant never issued a Social Security number do at each subsequent application if still without one?

    1. Reuse the first affidavit forever
    2. Bring a notarized letter from an employer
    3. Skip the identity proof requirement
    4. Sign a new affidavit in person each time, unless a number can then be provided
    Show answer

    Sign a new affidavit in person each time, unless a number can then be provided. The affidavit is not a lifetime pass: each subsequent application requires a new in person signing unless the applicant can finally provide a number for matching. Reusing the first form forever contradicts the renewal requirement written beside the original oath. An employer letter is a residency proof option, not a substitute oath. Identity proof is never skipped; original applicants still need primary documentation. The department computer link checks any provided number against Social Security Administration records for a match.

18. 18. About how long does it take to cancel the effects of one drink, and of three drinks?

    1. Thirty minutes per drink regardless of count
    2. One hour for one drink; about three hours for three drinks
    3. Coffee reduces one drink to fifteen minutes
    4. One drink clears only after eight hours of sleep
    Show answer

    One hour for one drink; about three hours for three drinks. The manual says it takes about one hour to cancel the effects of one drink and about three hours for three drinks. It says the liver can oxidize about one drink per hour and that coffee, exercise, a cold shower, or other measures cannot speed this process; only time can sober a person up. That halves the needed clearing time. Coffee cannot speed liver processing.

19. 19. Before a financial responsibility revocation takes effect, how and by when may the driver request an administrative hearing?

    1. By phone at any time after revocation
    2. In person within 30 days after revocation
    3. Only through an insurance agent
    4. In writing, submitted on or before the effective date of the proposed revocation
    Show answer

    In writing, submitted on or before the effective date of the proposed revocation. Before revocation, a driver may request an administrative hearing by submitting the request in writing on or before the proposed revocation’s effective date. Failure to satisfy the financial-responsibility requirements described in this section results in revocation of driving and registration privileges. The request must be in writing. After revocation is already too late. The manual requires a written request submitted by the deadline; it does not require using an insurance agent.

20. 20. Why should you avoid flashing your headlights at a deer standing in the road?

    1. Flashing legally counts as an improper signal
    2. High beams permanently blind deer and draw others
    3. Deer always charge toward flashing lights
    4. Deer tend to fixate on headlights, so flashing them may cause the animal to freeze in the road
    Show answer

    Deer tend to fixate on headlights, so flashing them may cause the animal to freeze in the road. Deer tend to fixate on headlights, so flashing them may cause a deer to freeze in the road. If you have time to avoid hitting an animal, reduce speed, tap the brakes to warn drivers behind, and sound the horn. If a collision seems inevitable, keep control and do not swerve to avoid the animal. The reason given in the manual is that flashing may cause the deer to freeze in the road.
