1. What must you do before changing lanes, in addition to signaling and checking your mirrors?
Show answer
Answer D: Glance over your shoulder to check the blind spot the mirrors do not cover
Mirrors leave an area beside and behind the vehicle that they cannot show, so a quick head check is needed before the vehicle moves sideways.
-
2. On a two-lane road, a solid yellow line runs on your side of the center while a broken yellow line runs on the other side. What does this mean?
Show answer
Answer D: You may not pass, although oncoming drivers may
Passing restrictions are read from the line closest to your own lane, so a solid yellow line on your side creates a no-passing zone for you alone.
-
3. Why can an oncoming vehicle that looks comfortably far away leave you far less room than you expect?
Show answer
Answer D: You and that vehicle close the gap at the sum of both your speeds
Two vehicles approaching at 55 mph each close the distance between them at about 110 mph, so the gap disappears in half the time you would expect.
-
4. 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.
-
5. On loose gravel or deep fresh snow, how does an antilock system affect the stopping distance?
Show answer
Answer D: It can lengthen it, although you keep the ability to steer
On loose surfaces a locked wheel piles up a wedge of gravel or snow that helps it stop, so the antilock stop can be longer even though steering still works.
-
6. The low sun is directly ahead and glare makes it hard to see. What should you do?
Show answer
Answer C: Slow down, use the sun visor or sunglasses, and increase following distance
Sun glare can hide pedestrians, brake lights and signals. Reducing speed and adding space gives you time to react to what you cannot yet see.
-
7. At a rural intersection a beacon flashes yellow toward the main road and red toward the side road. How is each approach treated?
Show answer
Answer A: The main road slows and proceeds, the side road stops
An intersection control beacon assigns flashing yellow to the road with priority and flashing red to the approach that must stop and yield.
-
8. You arrive at an intersection with no signs, no signals and no markings at the same time as a vehicle on the road to your right. What must you do?
Show answer
Answer B: Yield to the vehicle on your right
At an uncontrolled intersection you must yield to a vehicle already in the intersection or approaching from your right.
-
9. A driver extends the left arm out the window and bends it upward at the elbow. What does this signal mean?
Show answer
Answer B: A right turn
The left arm bent upward at the elbow is the standard hand signal for a right turn.
-
10. How should a pregnant driver or passenger wear a seat belt?
Show answer
Answer A: Lap belt below the belly across the hips, shoulder belt across the chest
A properly worn belt protects both mother and baby. The lap portion goes low under the belly, snug across the hip bones, and the shoulder belt crosses between the breasts.
-
11. A driver reaches this sign and the intersecting roadway is completely clear. What is required?
Show answer
Answer D: Slowing to a speed that allows stopping, then going on without stopping if the way stays clear
This control asks the driver to slow down and be ready to stop, and a full stop becomes necessary only when traffic or pedestrians would otherwise be interfered with.
-
12. You are entering a marked work zone. What should you expect?
Show answer
Answer B: A reduced posted speed, narrowed or shifted lanes, and traffic that may stop suddenly
Work zones change the geometry of the road and can bring traffic to a halt without warning, so the posted work zone speed and increased following distance both apply.
-
13. You must slow suddenly on a highway and a vehicle is following close behind you. What helps prevent a rear-end collision?
Show answer
Answer D: Tapping the brake pedal early so your brake lights flash a warning
Early brake light flashes give the driver behind more time to react, and slowing gradually instead of suddenly reduces the chance of being struck.
-
14. You signaled a lane change and the signal did not switch itself off afterwards. Why does that matter?
Show answer
Answer B: Other drivers may act on a turn you do not intend to make
A signal left on tells other drivers you are about to turn, and someone may pull out in front of you. Cancel it as soon as the maneuver is finished.
-
15. You are following closely behind a vehicle you intend to pass on a two-lane road. What should you do first?
Show answer
Answer D: Drop back to give yourself room to build speed before you pull out
From close behind you cannot see far enough ahead and you have no room to gather speed, so the pass takes longer and starts blind.
-
16. The hood of your vehicle flies open while you are driving and blocks your view. What should you do?
Show answer
Answer A: Look through the gap beneath the hood or out the side window, slow down and pull off the road
You usually still have a narrow view under the raised hood or through the side window. Use it to steer, slow gradually and get clear of traffic before securing the hood.
-
17. Which of these does NOT affect how fast alcohol reaches the bloodstream?
Show answer
Answer A: How confident the drinker feels
Food, the strength of the drinks and the speed of drinking all change how fast alcohol is absorbed, but a drinker's confidence changes nothing at all.
-
18. Before making a right turn at an intersection, what should you check besides oncoming traffic?
Show answer
Answer B: Your right blind spot and the crosswalk, for cyclists and pedestrians
Right turns often catch a cyclist or a pedestrian coming up on the right, so check the blind spot and the crosswalk before you turn.
-
19. A driver ahead brakes for no reason you can see, again and again. What should you do?
Show answer
Answer B: Increase your following distance and be ready for yet another stop
Unexplained braking tells you the driver is unsure or distracted, so the safe answer is more room, not less.
-
20. A dust storm is blowing across the highway ahead of you. What is the recommended response?
Show answer
Answer B: Leave the road if you can, park well clear and take your foot off the brake
Get well off the pavement, switch the lights off and keep your foot off the brake, so drivers still on the road do not follow your tail lights off the highway.
-
21. A yellow diamond showing a truck is posted beside a quarry entrance. What is it warning about?
Show answer
Answer A: Trucks turning onto the highway from that entrance
A truck crossing or trucks entering sign is used where heavy vehicles pull onto the road from a site, and they accelerate slowly once they are on it.
-
22. An orange background with a black legend on a sign indicates
Show answer
Answer B: a temporary traffic control or work zone situation
Orange is reserved for temporary traffic control signing, so an orange sign means conditions have been altered for work or another temporary operation.
-
23. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
24. A speed limit sign carries a second panel reading TRUCKS 55. What does that panel do?
Show answer
Answer B: It sets a lower legal limit for trucks
A truck speed limit panel is regulatory, so trucks are bound by the lower figure while other traffic keeps to the main limit.
-
25. You have finished a distracting task and your eyes are back on the road. What is true?
Show answer
Answer A: Your full attention takes a while to come back
Studies of drivers show attention lags behind the eyes for many seconds after a phone or a screen task, so the danger continues after the task is over.
-
26. A SHOULDER DROP OFF sign warns that
Show answer
Answer B: there is a step down from the pavement to the shoulder
The sign is used where the edge of the pavement stands several inches above the shoulder, which can grab a wheel and pull the vehicle sideways.
-
27. Another driver takes a right of way that was legally yours. What should you do?
Show answer
Answer A: Give way to the other driver and avoid the crash, whatever the law says
Right of way is something you give, not something you take, and being in the right is no protection in a collision.
-
28. 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.
-
29. Why do young drivers carrying several friends face a higher crash risk?
Show answer
Answer D: Because young passengers are a strong source of distraction and pressure
Crash risk for new drivers rises with each extra young passenger, mainly through distraction and social pressure.
-
30. Which family of signs normally uses a rectangle that is wider than it is tall?
Show answer
Answer B: Guide signs, which name routes and destinations
Guide signs are laid out as horizontal rectangles because they have to carry route numbers, place names and distances side by side.
