1. You are driving at night through heavy falling snow. Which headlight setting works better and why?
Show answer
Answer C: Low beams, because high beams bounce off the falling flakes back at you
Falling snow reflects light the way fog does, so high beams build a white wall of glare while low beams still give a usable view.
-
2. What does this sign require of the driver?
Show answer
Answer D: Reducing speed and being ready to stop at the intersection ahead
The advance notice asks the driver to slow and be ready to stop, while whether a stop is actually needed depends on the indication displayed on arrival.
-
3. Two left-turn lanes are available and you must turn right again a short distance after the turn. Which of the two should you use?
Show answer
Answer D: The right one, so you finish nearer the right side of the new street
Each turn lane feeds the matching lane of the new street, so choosing the right-hand of the two left-turn lanes leaves you closer to the side you will need.
-
4. A driver ignores this sign and passes on the opposite side. What is the main risk?
Show answer
Answer B: Ending up on the wrong side of a divider, facing traffic coming the other way
The sign settles which side of a fixed divider is the legal one, so taking the other side sends the vehicle into the opposing stream or straight at the obstruction.
-
5. An emergency vehicle with flashing lights and a siren is approaching from behind on a two-way street. What should you do?
Show answer
Answer C: Pull over to the right edge of the road and stop until it passes
Clearing a path by pulling to the right and stopping gives the emergency vehicle a predictable route, while stopping in mid-lane or inside an intersection blocks that path.
-
6. This sign comes into view ahead of a driver who has already started along a ramp. What should the driver do?
Show answer
Answer B: Pull clear where it is safe, then turn around and leave the ramp traveling properly
The driver is traveling against the legal flow, so the safest response is to stop clear of the lanes, turn the vehicle around and get off the ramp before meeting traffic head on.
-
7. 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.
-
8. Why is being thrown out of a vehicle in a crash so dangerous?
Show answer
Answer C: Because you strike the road or other objects at high speed, and rarely survive
Ejection is one of the deadliest outcomes of a crash, and a fastened belt is what keeps a person inside the vehicle.
-
9. You reach a stop-controlled intersection at the same time as a driver on your left, but that driver is already moving through the crossing. Who goes first?
Show answer
Answer C: The driver who is already inside the intersection
A vehicle already in the intersection has the right of way, and the rule about yielding to the right applies only before anyone has entered.
-
10. Which of these would appear as a symbol on a blue general service sign?
Show answer
Answer A: A hospital
General service signs cover facilities such as hospitals, fuel, food, lodging, camping, telephones and rest areas, all shown in white on blue.
-
11. You arrive at a four-way stop after two other vehicles have already stopped there. When is it your turn?
Show answer
Answer A: After both of the earlier vehicles have gone
Vehicles clear a four-way stop in the order they arrived, so the third driver to stop is the third to go.
-
12. A car is coming straight at you in your lane and there is no time for it to move back. What should you do?
Show answer
Answer A: Brake, sound the horn and steer to the right, toward the shoulder or ditch
Steering right takes you away from the other vehicle even if its driver corrects course, and the shoulder or ditch is survivable.
-
13. You are driving through patchy fog on a highway. What should you be ready for?
Show answer
Answer B: Sudden dense banks where visibility drops within a few car lengths
Patchy fog can go from clear to nearly blind in a moment, so keep your speed low enough that a sudden bank does not leave you without room.
-
14. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
15. You are traveling at 55 mph and see a vehicle ahead moving at about 15 mph. What is the hazard?
Show answer
Answer A: You reach it far sooner than you expect
At a 40 mph difference you cover the gap in a few seconds, which is why drivers strike slow vehicles they saw in plenty of time.
-
16. Your brake pedal sinks to the floor and the vehicle does not slow down. What is a reasonable sequence of actions?
Show answer
Answer C: Pump the pedal, shift to a lower gear and apply the parking brake gradually while steering to a safe spot
Pumping can rebuild pressure in a partly failed system, a lower gear adds engine braking, and easing on the parking brake slows the vehicle without locking the wheels.
-
17. You are turning left across tracks that run along the center of the street. What should you do before crossing them?
Show answer
Answer B: Look along the tracks in both directions and cross only when clear
Rail vehicles running in the street can arrive from either direction and cannot stop quickly, so look along the tracks before you turn across them.
-
18. You have fitted small convex blind spot mirrors to the door mirrors. What is true of them?
Show answer
Answer A: They help a good deal, but you should still look over your shoulder as well
Add-on mirrors reduce but do not remove the blind spot, and they make vehicles look smaller and further away.
-
19. The curb ahead is signed as a bus stop. May you wait there with your vehicle?
Show answer
Answer C: No, the space must stay clear for buses
A bus stop must stay open so that a bus can reach the curb and let passengers on and off safely, so no other vehicle may occupy it.
-
20. You are driving along a street lined with parked cars. What should you watch for?
Show answer
Answer B: Doors opening, vehicles pulling out and pedestrians stepping from between cars
Parked cars hide people and can move without warning. Keep as much space from them as you safely can and cover the brake.
-
21. Is dictating a message by voice a safe alternative to typing one?
Show answer
Answer C: No, it still takes attention from driving
Composing and checking a spoken message loads the mind and usually pulls the eyes to the screen anyway, so research finds it no safer than other phone use.
-
22. A flagger turns the paddle to the orange face reading SLOW. What does that tell approaching drivers?
Show answer
Answer D: Reduce speed and continue through the work area with care
The SLOW face keeps traffic moving at a reduced speed while workers or equipment are close to the travel lanes.
-
23. A driver sees this sign on a quiet road with no other traffic in either direction. What is the correct response?
Show answer
Answer C: Slow down, look and listen for a train, and be ready to stop
The sign gives advance notice of a highway-rail grade crossing, so the driver reduces speed, checks both directions along the tracks and keeps enough room to stop short of the rails.
-
24. What should a driver expect a short distance beyond this sign?
Show answer
Answer C: Another road crossing the one being traveled
Traffic may enter or cross from either side at the intersection ahead, so the driver should ease off, cover the brake and check both approaches.
-
25. You have begun to move into the next lane when the gap you were aiming for closes. What is the safest action?
Show answer
Answer C: Return to your own lane, cancel the signal and wait for a better gap
An unfinished lane change leaves you in a space that no longer exists, and the lane you came from is still yours.
-
26. You are turning left from a two-way street onto a one-way street. Which lane should you enter?
Show answer
Answer C: The first lane open to traffic on the left side of the one-way street
Turn left from the lane closest to the center line and finish in the first available lane on the left of the one-way street, then change lanes if you need to.
-
27. You are about to drive a rental car that you have never driven before. What should you do?
Show answer
Answer A: Adjust the seat and the mirrors and find the controls before moving off
Hunting for the wipers or the lights in traffic is a distraction, so learn the layout while the vehicle is stopped.
-
28. Why is it useful to watch the vehicle two or three places ahead of you?
Show answer
Answer C: You get an earlier warning of slowing traffic than brake lights give
Trouble travels back through a line of traffic, so seeing it start several vehicles ahead gives you a head start on braking.
-
29. You have parked but your car sits across the line into the next space. What should you do?
Show answer
Answer B: Pull out and park again fully inside one space
A car over the line takes a space away from someone else and leaves too little room for the doors of the vehicles beside it.
-
30. You pass into a work zone with a reduced speed limit but you see no workers. What speed applies?
Show answer
Answer D: The posted work zone limit, whether or not workers are present
A posted work zone speed limit is a regulatory limit in force at all times, and narrow lanes and uneven surfaces remain dangerous when nobody is working.
