1. A broken white line separates your lane from the lane on your right. What does it permit?
Show answer
Answer C: Changing lanes when it is safe to do so
A normal broken white line marks a boundary between lanes traveling the same way that road users may cross when it is safe.
-
2. A regulatory sign reads TURN ON HEADLIGHTS NEXT 15 MILES. What does it require?
Show answer
Answer C: Low beam headlights on for that stretch, day or night
Such a section is signed where a road is hard to see along, and the requirement is to run headlights, not just daytime running lamps, through the whole stretch even in bright daylight.
-
3. When is a driver at the highest risk of falling asleep at the wheel?
Show answer
Answer B: Late at night, early morning and mid afternoon
The body clock produces its deepest dips in alertness in the small hours and again in the middle of the afternoon, and crash records follow those dips.
-
4. Why are ordinary denim jeans a poor choice for riding?
Show answer
Answer C: They wear through in a slide, giving little abrasion protection
Light denim abrades away in a fraction of a second on pavement, while leather or purpose made textile gear stays intact long enough to protect the skin underneath.
-
5. Your vehicle breaks down on a busy highway. What is the safest course of action?
Show answer
Answer D: Get it as far off the roadway as possible, switch on the hazard lights and keep clear of the traffic lanes
A vehicle left in or beside a travel lane is a hazard, so move it well off the road, make it conspicuous with hazard lights and keep yourself away from passing traffic.
-
6. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
7. Why do watering eyes matter so much to a rider?
Show answer
Answer D: Blurred vision delays the moment you see and react to a hazard
Wind makes unprotected eyes water, and even a brief loss of clear vision at road speed costs you the distance you need to react.
-
8. How does eating a large meal before drinking affect impairment?
Show answer
Answer D: It slows absorption but the alcohol still reaches the blood and impairs you
Food delays how quickly alcohol enters the bloodstream, which can make the peak arrive later, but all of the alcohol is eventually absorbed.
-
9. A vehicle in the lane beside you has stopped at a crosswalk. What should you do?
Show answer
Answer C: Stop as well, because that driver may be yielding to a pedestrian you cannot see
The stopped vehicle hides the crosswalk from you, and passing it is a leading cause of collisions with pedestrians who are already crossing.
-
10. You are driving on a two-lane road approaching the crest of a hill. Where should you position your vehicle?
Show answer
Answer D: Toward the right side of your lane, in case an oncoming vehicle is over the center line
You cannot see what is beyond a crest, and oncoming drivers sometimes drift across the center. Keeping right and slowing gives you a margin.
-
11. Every signal head at an intersection is flashing red in all directions. How should you treat the intersection?
Show answer
Answer C: As an all-way stop, stopping and then going in turn
Red flashing in every direction means each approach must stop, so the intersection works exactly like an all-way stop.
-
12. What should a group agree on before the ride begins?
Show answer
Answer A: The route, the fuel and rest stops, and the hand signals to be used
Settling the route, the stops and the signals before departure keeps the group together and avoids sudden, confusing decisions once it is moving.
-
13. A bicyclist in the bike lane ahead of you signals and starts to move left toward the turn lane. What should you do?
Show answer
Answer A: Slow down and let the rider move across
A bicyclist who needs to leave the bike lane to turn left is changing lanes like any driver, and following traffic should make room.
-
14. The handlebars begin to shake violently in a wobble at speed. What is the correct response?
Show answer
Answer C: Grip the bars firmly and close the throttle gradually, without braking
Braking or accelerating during a wobble usually makes it worse, so the rider holds on, rolls off gradually, and pulls off the road to find the cause.
-
15. How can the vehicle ahead of you help you read the road at night?
Show answer
Answer A: Its headlights light the road further ahead than yours can reach
The lights of the vehicle ahead reach beyond your own beam, so its brake lights and the way it moves warn you about holes, turns and hazards you cannot yet see.
-
16. The center line beside your lane is a broken yellow line. What does it allow?
Show answer
Answer D: You may cross into the opposing lane to pass when it is safe and clear
A broken yellow center line marks a passing zone where traffic in that direction may cross into the opposing lane to pass when the way ahead is clear.
-
17. The group has become separated and the leader wants to wait for the missing riders. Where should the leader pull in?
Show answer
Answer C: In a parking area or other space that is clear of moving traffic
Waiting somewhere off the roadway keeps the parked machines and their riders out of traffic and gives the arriving riders room to pull in safely.
-
18. You are in a minor collision on a busy road. No one is hurt and both vehicles can be driven. What is the recommended thing to do?
Show answer
Answer C: Move the vehicles out of the travel lanes to a safe spot before exchanging information
Vehicles left in traffic after a minor crash invite a second, often worse, collision. Clearing the lane protects everyone, and you still exchange details and report as required.
-
19. A bike lane on your right is marked with a dashed line for the last stretch before the corner. What does that dashed section allow you to do?
Show answer
Answer D: Merge into the bike lane after checking, and turn right from there
The dashed section is where drivers are meant to merge into the bike lane before turning, which puts cyclists behind the vehicle instead of beside it.
-
20. Which helmet style gives the rider the most coverage?
Show answer
Answer C: A full face helmet
A full face helmet covers the chin and jaw as well as the skull, protecting the area that open styles leave exposed.
-
21. What is a microsleep?
Show answer
Answer D: A few seconds of sleep, sometimes with the eyes open
A microsleep is an involuntary lapse of a few seconds during which the driver is asleep and the vehicle travels blind, often without the driver knowing.
-
22. 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.
-
23. A traffic signal is displaying a flashing red light. How must you treat it?
Show answer
Answer D: Stop completely, then proceed when the way is clear
A flashing red carries the same meaning as a stop sign: come to a full stop, then go only when it is safe.
-
24. You are driving on a divided highway and see a solid yellow line along the left side of your lanes. What does it tell you?
Show answer
Answer D: It marks the left edge of the roadway for your direction
On a divided highway or a one-way roadway, the left edge of the traveled way is marked with a solid yellow line.
-
25. When should speed be adjusted for a curve?
Show answer
Answer B: Before entering the curve
Slowing before the curve lets the rider hold a steady or slightly increasing throttle through it, which settles the suspension and keeps traction predictable.
