1. What actually lowers the amount of alcohol in a person's blood?
Show answer
Answer D: The passage of time
The body eliminates alcohol at its own steady rate, so only time reduces blood alcohol. Coffee or a cold shower may make a person feel more awake while still impaired.
-
2. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
-
3. The vehicle you want to pass is traveling close to the speed limit. What should you do?
Show answer
Answer C: Stay behind, because a pass may not take you over the limit
The speed limit applies while passing too. If you cannot complete the pass without exceeding it, do not start the pass.
-
4. The vehicle you have borrowed is larger and heavier than your own. How should you drive it?
Show answer
Answer B: Allow more room for stopping and for turns until you are used to it
Extra weight and length mean longer stopping distances and wider turns, so give yourself more room until you are used to it.
-
5. An overhead sign shows that the right lane is EXIT ONLY. What does that mean if you intend to stay on the highway?
Show answer
Answer B: You have to move out of that lane before the exit
An exit only lane leaves the highway completely, so a driver continuing on the highway has to change lanes before it does.
-
6. You approach an intersection where the signal is flashing yellow. What should you do?
Show answer
Answer D: Slow down and cross the intersection with caution
A flashing yellow signal warns you to slow down and cross with care; it does not require a stop, but it does not give you priority either.
-
7. 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.
-
8. Loose items slide around your car and rattle every time you brake. What is the answer?
Show answer
Answer C: Secure them before you start driving
Sliding objects pull your attention and can roll under the pedals, so stow them in the trunk or wedge them before the trip rather than chasing them during it.
-
9. Many signs use a symbol instead of words. The main advantage is that a symbol
Show answer
Answer C: can be read from farther away and by more people
A symbol is recognized at greater distance than a line of text and does not depend on the reader knowing English.
-
10. You have signaled and pulled up level with the car in front of an empty curb space. What comes next?
Show answer
Answer A: Reverse slowly while turning the wheel toward the curb
From alongside the forward car you back in on a turn toward the curb, then straighten and swing the front in as the rear reaches the space.
-
11. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
12. How long must a supervising driver who is not the parent or guardian have held a Class D license before supervising a Delaware permit holder?
Show answer
Answer B: 5 years
Delaware requires a non-parent supervising driver to have held a Class D license for that length of time in addition to meeting the age requirement.
-
13. Why is this restriction used so often on a divided road just before a crest or a bend?
Show answer
Answer A: Because a vehicle turning across the median there stays hidden from approaching drivers until it is too late
The maneuver needs a long gap and good visibility, and where sight distance is short an approaching driver has no time to react to a vehicle turning across the road.
-
14. You find yourself in a lane that must turn, you wanted to go straight, and you cannot change lanes safely. What should you do?
Show answer
Answer D: Make the required turn and find another route
Going straight from a mandatory turn lane surprises everyone around you, while a wrong turn costs only a few extra minutes.
-
15. A city transit bus at a stop ahead of you switches on its left signal. What should you do?
Show answer
Answer D: Slow and let the bus pull back into traffic
A bus needs a long gap to rejoin traffic, and yielding to a signaling transit bus keeps the whole line of traffic moving safely.
-
16. Why is heavy braking a poor idea while two wheels are still on a soft shoulder?
Show answer
Answer B: The two sides have different grip, so the vehicle can pull sharply
With one pair of wheels on pavement and the other on loose material, hard braking slows one side more than the other and swings the vehicle around.
-
17. The light ahead is green, but traffic beyond the intersection is backed up so far that you could not clear it. What is the correct action?
Show answer
Answer D: Wait behind the stop line until there is room on the far side
Entering an intersection you cannot clear blocks cross traffic and pedestrians, so you should hold your position until space opens on the other side.
-
18. What is the only reliable remedy for a driver who is sleepy?
Show answer
Answer A: Sleep
Caffeine, fresh air and noise may make you feel alert for a few minutes, but they do not remove the need for sleep. Stop somewhere safe and rest.
-
19. How can you keep space at the sides of your vehicle in heavy traffic?
Show answer
Answer D: Drive in the gaps between the other vehicles rather than beside them
Travelling in the open spaces rather than alongside others keeps a way out open on at least one side.
-
20. A rear tire blows out on the highway. How does the vehicle usually behave?
Show answer
Answer C: The back end weaves or fishtails from side to side
A rear failure shows up as the tail wandering rather than a pull on the steering, so hold the wheel straight and let the speed drop gradually.
-
21. You feel fine twenty minutes after your last drink. Why is that a poor guide to driving?
Show answer
Answer B: Your blood alcohol level can still be rising
Alcohol keeps being absorbed for some time after the last drink, so a driver who feels able at the door can be more impaired a few miles down the road.
-
22. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with turn arrows painted inside it. What is that lane for?
Show answer
Answer C: Left turns made by traffic traveling in either direction
That marking pattern identifies a two-way left-turn lane, which drivers approaching from both directions may use to prepare for a left turn.
-
23. Cones and drums mark a shifted lane through a work zone. What should you do?
Show answer
Answer A: Follow the path that they mark and stay inside it
Channelizing devices define the temporary travel path, and the space on the other side of them belongs to the workers.
-
24. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you
A truck has a deep blind spot directly behind it, and tailgating also hides everything in front of the truck from you. Drop back so you can see and be seen.
-
25. A yellow diamond showing two vertical arrows, one pointing up and one pointing down, warns that
Show answer
Answer A: the road ahead carries traffic in both directions
The two-way traffic sign warns that the roadway ahead is not divided and that vehicles will be coming from the opposite direction.
-
26. 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.
-
27. How do you avoid the sharp nod at the end of a stop?
Show answer
Answer A: Ease the pedal pressure off slightly just before the vehicle stops
The nod comes from the suspension unloading at the instant the wheels stop. Releasing a little pressure at the end lets the vehicle settle smoothly.
-
28. How long should a young child ride in a rear-facing child seat?
Show answer
Answer D: Until the child outgrows the height or the weight limit of the seat
Rear facing is the safest position and should be kept until the child reaches the top height or weight allowed by the seat.
-
29. You have a small extinguisher and a fire has started under the hood. What is the safe way to use it?
Show answer
Answer B: Release the latch and spray through the gap without raising the hood at all
Opening the hood feeds the fire a rush of air, so spraying through the gap at the base of the flames is both safer and more effective.
-
30. An arrow panel at a work zone displays a flashing arrow pointing to the left. What does it require?
Show answer
Answer C: Move out of the closed lane into the lane on the left
A flashing or sequential arrow on an arrow panel directs traffic out of a closed lane and into the lane the arrow points to.
-
31. A traffic signal ahead is showing a flashing red light. What does it require?
Show answer
Answer C: Stop completely, then go when the way is clear, as at a stop sign
A flashing red light has the same meaning as a stop sign: stop completely, yield to traffic and pedestrians, then proceed when it is safe.
-
32. What is the safe way to carry a dog in a car?
Show answer
Answer C: In a secured crate, or in a harness attached to a seat belt anchor
An unrestrained animal distracts the driver and becomes a heavy projectile in a crash, so it should be crated or harnessed.
