1. A regulatory message is normally carried on a sign whose shape is
Show answer
Answer A: a rectangle standing taller than it is wide
Regulatory signs that state a law, such as speed limits and turn restrictions, use a vertical rectangle with a black legend on a white background.
-
2. Which rough check suggests that a helmet is a novelty shell rather than a certified helmet?
Show answer
Answer C: It weighs about a pound, far less than a certified helmet
A certified helmet weighs roughly three pounds because of its shell and thick liner, while a novelty shell is very light. Weight is only a clue, and the certification label is the real check.
-
3. Why can a mild afternoon still chill a rider dangerously on the highway?
Show answer
Answer B: Riding speed creates a wind chill well below the air temperature
Air moving over the body at highway speed strips heat far faster than still air, so a comfortable temperature at a standstill can cause serious chilling in an hour of riding.
-
4. A large X with the letters R and R beside it is painted across your lane. What does it mean?
Show answer
Answer A: A railroad crossing lies a short distance ahead
The pavement marking repeats the advance warning for a grade crossing, and it is used on paved approaches where speeds are high or where gates are installed.
-
5. You have just ridden through a stretch of deep standing water. What should you do next?
Show answer
Answer B: Ride slowly and apply the brakes lightly to dry them out
Wet brakes can grab or barely work at all, and gentle pressure while moving slowly heats and clears them before they are really needed.
-
6. On which approach is this sign normally installed?
Show answer
Answer C: On the road that ends, far enough ahead for the driver to slow down
The warning belongs on the approach that terminates, placed early enough that the driver can lose speed and choose a direction before reaching the junction.
-
7. 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.
-
8. Your front wheel drops off the edge of the pavement onto a lower shoulder. What is the safest way back?
Show answer
Answer D: Ride straight, slow down, then turn back sharply enough to cross the edge
Trying to climb a raised pavement edge at a shallow angle lets the tire slide along it, so the rider settles first and then crosses the edge at a sharp angle.
-
9. On a rainy road, where can a rider usually find the best traction?
Show answer
Answer A: In the tire tracks left by the vehicles ahead
Vehicles ahead push water aside and keep their tracks clearer of oil, so those tracks generally give better grip than the rest of the lane.
-
10. A sign with a yellow background and a black legend generally conveys
Show answer
Answer B: a general warning
Yellow is the background color used for general warning signs, so a yellow sign tells the driver to expect something ahead rather than to obey a rule.
-
11. A sign on a freeway restricts trucks to the two right-hand lanes. What should a car driver expect in those lanes?
Show answer
Answer A: More heavy vehicles and slower changes of speed
A truck lane restriction concentrates heavy vehicles on the right, and those vehicles accelerate, brake and change lanes far more slowly than cars.
-
12. You are very angry after an argument and about to drive. What should you know?
Show answer
Answer A: Strong emotions can impair judgment and attention much like alcohol
Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.
-
13. Yellow signs each showing one large black arrowhead, installed in a row along the outside of a curve, are
Show answer
Answer D: chevron alignment signs marking the change of direction of the curve
Chevron alignment signs are placed on the outside of a curve so that several are in view at once, letting the driver judge how sharply the road turns.
-
14. A separate right-turn lane leads onto the cross street and carries a yield sign. What does it require?
Show answer
Answer D: Slowing and giving way to traffic and people, stopping if needed
A yield requires you to slow, give way to traffic in the lane you are joining and to pedestrians, and stop only if that is what safety demands.
-
15. Should a rider change lanes while passing through an intersection?
Show answer
Answer A: No, the lane change should be completed before or after the intersection
Drivers entering and turning at an intersection are watching lanes rather than a machine moving between them, and lane markings are usually broken there.
-
16. What is the correct way to ride across a stretch of slippery pavement?
Show answer
Answer C: Reduce speed before you reach it, avoid sudden moves, and use both brakes gently if you must brake
The speed must come off before the slippery area, and once the tires are on it every input, braking included, has to be smooth and gentle.
-
17. Why does the situation ahead of this sign deserve extra care from a motorcyclist?
Show answer
Answer C: Because a narrow machine is easy to overlook in a mirror or a blind spot
A motorcycle fills very little of a mirror and disappears easily into a blind spot, so the rider should adjust speed and lane position to stay visible where the streams come together.
-
18. Halfway through a curve you realize you are going too fast. What is the best response?
Show answer
Answer C: Ease off the gas gently and look where you want to go
Easing off transfers a little weight to the front tires without upsetting the balance, and looking through the curve keeps your steering smooth.
-
19. Why is the staggered formation abandoned in a curve?
Show answer
Answer D: Because each rider needs the full width of the lane to choose a line through the curve
In a curve every rider must be free to use the whole lane to set up an entry and an exit line, which is impossible while holding a fixed side position.
-
20. A piece of farm machinery ahead of you is wider than its own lane. What should you do?
Show answer
Answer C: Hold back until you can see far enough to pass safely
Wide equipment leaves no gap inside the lane and may use part of the other side, so a pass needs a long clear view of the road ahead.
-
21. At a railroad crossing with no gates and no flashing lights, the crossbuck is normally combined with which sign?
Show answer
Answer C: A yield sign, or a stop sign where an engineering study calls for one
At a passive crossing the crossbuck forms an assembly with a yield sign, or with a stop sign when an engineering study or engineering judgment supports it, so the driver knows who must give way to the train.
-
22. A driver is tailgating you. Why is it a bad idea to tap or stab the brakes to warn them?
Show answer
Answer C: Because it cuts the little space they have and can cause a crash
Brake checking removes the small margin the tailgater has left and can provoke a collision; add space in front of you instead and let them pass.
-
23. After an hour on a hot highway your tire pressure reads higher than it did in the morning. What should you do?
Show answer
Answer D: Nothing, because pressure rises when tires heat up
Air expands as the tire warms, so a hot reading is normally above the cold setting. Bleeding air off would leave the tire underinflated once it cooled.
-
24. When may a driver of a motor vehicle use a marked bicycle lane?
Show answer
Answer C: Only to cross it when turning or entering the road where the markings allow
A bike lane is a lane for cyclists. Motor vehicles may only cross it to enter or leave the road or to make a turn where the markings permit.
-
25. You have a green light and an ambulance with lights and siren enters the intersection against its red. What should you do?
Show answer
Answer B: Stop and let the ambulance go through
An emergency vehicle answering a call may cross against a red, and every other driver yields to it whatever their own signal shows.
