1. Which of the four blind spots around a tractor-trailer is the largest?
Show answer
Answer A: The one on the right side of the truck
A truck has no-zones on all four sides, and the right-side blind spot is the largest because it runs back along the trailer and reaches across more than one lane.
-
2. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
3. A signal beside a fire station stays dark until apparatus is about to leave, when it shows yellow and then red. What must a driver do?
Show answer
Answer B: Stop on the red and wait until the signal goes dark again
An emergency vehicle signal is a real traffic signal, so its red indication must be obeyed while the apparatus pulls out into the street.
-
4. How does driving on overinflated tires affect the vehicle?
Show answer
Answer D: It gives a harsher ride and a smaller contact patch
An overinflated tire bulges in the middle, so less rubber touches the road, grip suffers and the ride becomes hard. The center of the tread wears first.
-
5. How does alcohol change the time a driver needs to respond to a hazard?
Show answer
Answer A: It slows it, so stopping takes longer
Alcohol is a depressant that lengthens the time between seeing a hazard and acting on it, which adds directly to the distance needed to stop.
-
6. A vehicle in front of you has already begun turning left into a driveway when the gap you were waiting for opens up. What should you do?
Show answer
Answer B: Wait and let that driver finish the turn
A vehicle that has lawfully started a maneuver keeps the right of way until it is finished.
-
7. Enhanced reference location markers differ from ordinary mileposts in that they
Show answer
Answer B: carry the route number and a mileage figure to the tenth of a mile
An enhanced reference location marker adds the route designation and carries the mileage to a tenth, so the point named is far more precise than a plain milepost.
-
8. You have entered a work zone where crews are working close to the open lane. What should you do?
Show answer
Answer A: Slow down and be ready for workers and machines
Workers and equipment cross the open lane without warning in a work zone, so reduced speed and attention on the road ahead are what keep them safe.
-
9. Where should a passenger sit on the motorcycle?
Show answer
Answer A: As far forward as possible without crowding the operator
Sitting well forward keeps the passenger weight close to the center of the motorcycle, which helps it handle closer to normal.
-
10. Where should you be looking as you steer through a turn?
Show answer
Answer C: Toward the point on the new road where you want to end up
Drivers steer toward what they look at, so looking through the turn to where you want to go keeps the path smooth and accurate.
-
11. In a tight, slow speed turn such as a parking lot U-turn, the rider should:
Show answer
Answer C: Lean the motorcycle while keeping the body upright
Keeping the body upright while the motorcycle leans lets the machine turn tightly and helps the rider hold balance at very low speed.
-
12. Besides motorist services and tourist information, a blue sign background is also used for
Show answer
Answer B: evacuation route signing
Blue is assigned to road user services, tourist information and evacuation routes, so hurricane and other evacuation routes are signed in blue.
-
13. The front brake lever feels soft and travels almost to the handgrip. What should the rider do?
Show answer
Answer D: Leave the motorcycle where it is until the brake system has been inspected
A spongy lever usually means air or fluid loss in the system, and a brake in that condition can fail completely under hard use.
-
14. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
-
15. A vehicle coming toward you has drifted into your lane. What should you do?
Show answer
Answer D: Slow down, sound the horn, flash your lights and steer to the right if possible
Moving right gives the other driver space to recover and keeps you out of the lane they are most likely to return to. Braking reduces the force of any impact.
-
16. Traffic is heavy and you find yourself riding level with a car in the next lane. What is the problem with staying there?
Show answer
Answer B: You sit in the driver's blind spot, so a lane change could hit you
Motorcycles disappear easily in a blind spot, so adjust your speed to ride ahead of or behind the other vehicle instead of beside it.
-
17. A sign with a brown background and a white legend guides road users to
Show answer
Answer B: parks, campgrounds and other recreational or cultural sites
Brown is reserved for recreational and cultural interest area signing, such as parks, historic sites and scenic areas.
-
18. The signal turns green as you approach an intersection. What is the safest practice?
Show answer
Answer B: Look left, then right, then left again, and make sure the intersection is clear before entering
A green light gives permission but does not guarantee the intersection is empty, and a quick scan catches a vehicle running the red or a pedestrian still crossing.
-
19. What is the best path through a curve where you can see all the way to the exit?
Show answer
Answer A: Start toward the outside, move toward the inside, then drift back out
Entering wide, cutting toward the inside and running back out straightens the path, which means less lean angle for the same speed and a better view.
-
20. You are driving on a road covered with a layer of wet fallen leaves. What should you expect?
Show answer
Answer B: As little grip as on ice, plus hidden markings and hidden holes
Wet leaves are as slippery as ice and they hide the lane lines and any potholes underneath, so slow well before curves and stops.
-
21. What should a passenger be told about moving around on the motorcycle?
Show answer
Answer A: To stay directly behind the operator and avoid sudden or unnecessary movement
Unexpected movement by a passenger upsets the balance of the machine, most of all at low speed and while the motorcycle is leaned over in a turn.
-
22. What does research say about the effect of a full coverage helmet on a rider's ability to see and hear traffic?
Show answer
Answer B: It leaves the view and the useful hearing a rider needs largely intact
Certified helmets leave far more peripheral vision than a rider needs to check traffic, and riders wearing them still hear the sounds that matter.
-
23. You are following a large truck on a two-lane road and cannot see past it. What should you do before deciding to pass?
Show answer
Answer D: Drop back so that your view of the road ahead opens up
Distance is what buys you a view around a large vehicle, and no decision to pass can be made from a position where you cannot see.
-
24. Which road feature is most likely to be slippery, particularly when wet?
Show answer
Answer D: Painted lane markings, manhole covers and steel plates
Paint and metal surfaces laid on top of the road offer far less grip than the pavement around them and become noticeably slick in the rain.
-
25. What happens to your field of vision as your speed increases?
Show answer
Answer C: It narrows, so you notice less at the sides of the road
The faster you travel, the more your useful field of view narrows toward the center, so a hazard coming from the side is seen late or missed altogether.
