1. What does a NARROW BRIDGE warning sign tell a driver?
Show answer
Answer A: The bridge is tighter than the road leading up to it
A narrow bridge still carries both directions, but with much less clearance than the approaches, so drivers should slow and hold their lane position carefully.
-
2. The rider ahead of you has just passed a slow vehicle on a two lane road. What does that tell you about your own pass?
Show answer
Answer C: Nothing, because you must judge the oncoming traffic yourself
Every pass uses up part of the gap, so the space that was ample for the rider ahead may be far too short by the time it is your turn.
-
3. What should riders expect from highway traffic when a group is merging?
Show answer
Answer C: Drivers will not hold a gap open for the group, so riders take real gaps
Other drivers do not treat a line of motorcycles as one vehicle, so each rider has to find a genuine gap rather than count on being let in.
-
4. How does becoming chilled affect a rider before any shivering is obvious?
Show answer
Answer D: It slows reactions and clouds judgment while the rider still feels fine
Cooling degrades reaction time and decision making before the rider notices it, so dress for the coldest part of the ride and stop to warm up rather than pressing on.
-
5. Two vehicles reach a four-way stop at the same moment from adjacent roads. Who should go first?
Show answer
Answer A: The driver on the right
When two drivers stop at a four-way stop at the same time, the driver on the left yields to the driver on the right.
-
6. You are first in the queue at a red light with a marked crosswalk. Where should your vehicle stop?
Show answer
Answer A: Behind the stop line, so that the crosswalk stays clear
Stopping short of the line keeps the crosswalk usable for people on foot and keeps your vehicle out of the path of turning traffic.
-
7. What is the correct technique for a maximum effort stop in a straight line?
Show answer
Answer A: Squeeze the front lever progressively and press the rear pedal, staying upright
Both brakes together give the shortest stop, the front is squeezed progressively as weight transfers forward, and the machine must be upright with the bars square.
-
8. Where is a road work ahead sign placed?
Show answer
Answer B: In advance of the work space or detour, so drivers are warned before reaching it
Advance warning signs are placed upstream of the work space or detour so that drivers have time to slow down and change lanes before reaching the activity.
-
9. When a funeral procession proceeds together through a red traffic light, what must other drivers do?
Show answer
Answer C: Not enter the intersection in a way that crosses the path of the funeral procession
Other drivers may not enter the intersection unless they can do so without crossing the funeral procession's path as it proceeds through together.
-
10. On a street with parking along the curb, the shared lane marking is painted well out from the curb face. What does that placement tell a bicyclist?
Show answer
Answer C: To ride clear of the doors of parked cars
The marking is set at least eleven feet from the curb where parking is allowed so that riders are guided outside the reach of an opening door.
-
11. You are wearing a high visibility jacket. How should that change the way you ride?
Show answer
Answer B: You still ride as though drivers have not seen you
Bright gear improves your odds of being noticed but guarantees nothing, so keep the lane position, space cushion and escape routes that protect you anyway.
-
12. 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.
-
13. A loaded truck is coming up an entrance ramp as you approach in the right lane of the freeway. What is the most helpful action?
Show answer
Answer A: Adjust your speed to open a gap for it
A heavy vehicle accelerates slowly, so opening a gap or moving over costs you seconds and saves the truck driver from being forced to stop on the ramp.
-
14. How much more energy must your brakes absorb if you double your speed?
Show answer
Answer D: About four times as much, since energy rises with the square of speed
Kinetic energy grows with the square of speed, so twice the speed means about four times the energy and a far longer braking distance.
-
15. You are turning left from a one-way street onto a two-way street. How should the turn be made?
Show answer
Answer B: Start in the far left lane and finish just to the right of the center line
Left turns begin from the lane nearest the left edge of the street you are leaving and must finish on the right-hand side of the center line of a two-way street.
-
16. On an unlit road, about how far ahead do high beams normally let you see?
Show answer
Answer D: About 350 to 500 feet ahead of the vehicle
High beams light roughly 350 to 500 feet of road and low beams far less, which is why night speeds have to be chosen around the beam, not the limit.
-
17. How should a group plan its rest stops on a long day?
Show answer
Answer A: Around the rider who tires first, with breaks before anyone is worn out
Fatigue destroys judgment long before a rider admits to it, so the break schedule follows the least rested rider rather than the strongest one.
-
18. A high-occupancy vehicle lane is separated from the general lanes by a pair of solid white lines with a gap every so often. Where may you enter or leave it?
Show answer
Answer D: Only at the openings where the solid lines are broken
The solid lines forbid crossing, so entry and exit are limited to the designated openings where the marking is broken.
-
19. Windblown sand has collected across the pavement at a rural intersection where you must stop. How should you handle the stop?
Show answer
Answer A: Do your braking on clean pavement before the sand, then roll across upright
Sand acts like ball bearings under the tires, so finish your braking on the clean surface ahead of it and cross the loose patch upright with no sudden inputs.
-
20. Your vehicle stalls on a railroad crossing and will not restart. What should you do first?
Show answer
Answer A: Get everyone out and away from the tracks immediately
Everyone must leave the vehicle and move well clear of the tracks at once, walking toward the train at an angle so that debris from an impact travels away from you.
-
21. You are approaching a driveway where a car waits to pull out and the driver is looking your way. What should you assume?
Show answer
Answer D: The driver may not have seen you, so cover the brakes and be ready to slow
Looking in your direction is not proof that a driver has registered a motorcycle, so cover the brakes and be ready to slow until the car is clearly staying put.
-
22. Why do bridges and overpasses deserve extra caution when temperatures are near freezing?
Show answer
Answer A: They lose heat from above and below, so they ice over before the surrounding road
A bridge deck is exposed to cold air on both surfaces and has no ground beneath it to hold heat, so ice can form there while the connecting road is still only wet.
-
23. You are traveling in the same direction as a funeral procession and want to get ahead of it. What should you not do?
Show answer
Answer B: Driving in between the vehicles of the procession
Most states prohibit driving into or through a funeral procession, and cutting into the line leaves the drivers behind with no lead vehicle to follow, so go around only where passing is permitted.
-
24. Which ability does alcohol usually affect first?
Show answer
Answer A: Judgment and self control
Alcohol reduces judgment and inhibition before a drinker notices any clumsiness, which is why an impaired driver often feels perfectly capable while already driving worse.
-
25. You are riding in the middle of a tight cluster of cars on a multilane road. What is the best way to improve your safety?
Show answer
Answer C: Ride slightly faster or slower to open space and get clear of the cluster
A rider hemmed in on all sides has nowhere to go, so change your speed a little to open an escape path and leave the crowd.
