1. How does marijuana affect a driver?
Show answer
Answer C: It slows reaction time and impairs judgment of time and distance
Marijuana impairs coordination, attention and the ability to judge speed and distance. Driving while impaired by it is illegal everywhere, even where its use is legal.
-
2. You are stopped in a line of traffic waiting at a red light. What is the safest way to wait?
Show answer
Answer A: Stay in first gear, keep watching the mirrors and leave a way out
A vehicle approaching from behind may not stop in time, and staying in gear with a gap ahead lets the rider move out of the way.
-
3. May you park in front of a public or private driveway?
Show answer
Answer A: No, blocking a driveway is prohibited even for a short time
Parking in front of a driveway blocks the property owner from entering or leaving, and the prohibition does not depend on how long you stay.
-
4. Why is an inexperienced rider a poor choice to lead a group?
Show answer
Answer C: The leader picks the pace, the gaps and the hazards for everyone behind
Every decision the leader makes is imposed on the riders behind, so leading demands more traffic judgment than any other position in the group.
-
5. A driver's blood alcohol concentration is below the legal limit, but the driver is visibly impaired. Can the driver be arrested?
Show answer
Answer C: Yes, driving while impaired by alcohol is an offense at any concentration
The per se figure, 0.08 percent in most states and 0.05 percent in Utah, is the level at which impairment is presumed. Impairment shown by driving behavior and field tests is enough on its own, because alcohol affects skills well before that number.
-
6. A line of short dashes set closer together than an ordinary lane line runs beside your lane where a ramp leaves the highway. What does a dotted line of that kind convey?
Show answer
Answer A: A warning that the lane is about to change function
Dotted lines give guidance or warning about a downstream change, such as a lane that becomes an exit only lane or a lane line carried across an intersection.
-
7. Your vehicle is burning at the roadside. How far away should everyone keep?
Show answer
Answer D: At least a hundred feet away from the vehicle and upwind, out of the drifting smoke
Burning vehicles give off toxic smoke and parts such as tires and struts can burst, so keep a long distance and stay upwind.
-
8. Traffic safety experts describe three kinds of driver distraction. Which set is correct?
Show answer
Answer A: Visual, manual and cognitive
Distraction takes the eyes off the road, the hands off the controls or the mind off driving, and many activities do more than one of those at once.
-
9. 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.
-
10. The left-turn signal facing you shows a flashing yellow arrow. What does it mean?
Show answer
Answer C: You may turn left after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow permits a left turn but gives no protection, so you must yield to oncoming vehicles and to people in the crosswalk.
-
11. What does a shaft final drive need checked before a ride?
Show answer
Answer D: The fluid level in the final drive housing, and any sign of leaks
A shaft drive runs in its own oil bath, so the pre-ride check is the fluid level and any leak around the housing seals rather than tension or slack.
-
12. The throttle sticks open and will not close when you roll it back. What should you do?
Show answer
Answer B: Squeeze in the clutch and shut the engine down with the cut-off switch
Pulling in the clutch cuts power to the rear wheel immediately, and the cut-off switch stops the engine without the rider letting go of the handlebars.
-
13. Heavy rain has left water standing on the highway. What is the main risk to a rider?
Show answer
Answer D: The tires can ride up on the water and lose contact with the road surface
At higher speeds a tire can no longer push standing water aside and starts to hydroplane, so the rider slows and eases off rather than braking or turning hard.
-
14. What should a passenger hold on to while the motorcycle is moving?
Show answer
Answer B: The operator's waist, hips or belt, or a handhold provided for the passenger
Holding the operator's waist, hips or belt, or a handhold designed for the passenger, keeps the passenger secure under acceleration and braking without pulling the operator off balance.
-
15. You are passing a large truck on an open highway in a strong crosswind. What should you expect?
Show answer
Answer A: A push toward the truck, then a push the other way as you clear it
The truck shelters you as you go by and then releases you into the full gust, so the load on the steering changes twice during the pass.
-
16. Why is hard braking the wrong response to a tire blowout at speed?
Show answer
Answer C: Because it can pull the vehicle further out of line and start it spinning
With one tire gone the braking forces are uneven, so heavy braking increases the pull to one side and can spin the vehicle.
-
17. A driver passes this sign on an open road. Over what stretch does the figure it sets stay in force?
Show answer
Answer A: From the sign onward, in every lane, until another sign sets a different figure
The figure governs the road from the sign onward and binds every lane, and it stays in force until a later sign sets a different one.
-
18. Two people drink the same amount of alcohol at the same time. Why might their blood alcohol concentrations differ?
Show answer
Answer C: Body weight, gender and food in the stomach affect the concentration
Smaller people and, on average, women reach higher concentrations from the same amount of alcohol, and an empty stomach speeds absorption. Counting drinks alone does not tell you your level.
-
19. You are leaving a freeway at an exit that has a deceleration lane. Where should you slow down?
Show answer
Answer C: After you have moved fully into the exit lane
Braking in a through lane surprises the traffic behind you, so you move into the exit lane at highway speed and then slow down inside it.
-
20. Traffic is entering the freeway from a ramp ahead of you and you are in the right lane. What should you do?
Show answer
Answer C: Move to another lane if it is safe, or adjust your speed to make room
Merging drivers may have little room to adjust. Helping them in by changing lanes or easing your speed prevents conflicts even though they must legally yield to you.
