1. When passing another vehicle, you should:
Make eye contact with the other driver.
Assume the other driver doesn’t see you. ✓
Honk your horn.
Wave to other drivers.
Answer: B. Assume the other driver doesn’t see you.
When passing another vehicle, you should assume the other driver does not see you. The handbook's communication section says other drivers may not notice your vehicle even when it is plainly visible. For passing, it gives a specific rule: whenever you are about to pass a vehicle, pedestrian, or bicyclist, assume they do not see you, because they could suddenly move in front of you. That is why you should expect the other driver to be unaware of you and drive carefully enough to avoid a crash, using a light horn tap or a night-time light flash only when it is legal.
Move quickly before other vehicles get into the lane you wish to occupy.
Move slowly, in case another vehicle is in the lane you wish to occupy. ✓
Not use your turn signal.
Never use the right lane.
Answer: B. Move slowly, in case another vehicle is in the lane you wish to occupy.
When changing lanes, you should move slowly and smoothly in case another vehicle is already in the lane you want to occupy. The handbook says to put your turn signal on before changing lanes and then change lanes slowly and smoothly. It gives the reason directly: a driver you did not see may get a chance to honk or avoid your vehicle. That matches the choice about moving slowly because another vehicle may be in the lane. The passage does not set an exact speed for lane changes; it tells you to make the move gradual and controlled.
3. When driving at highway speeds, you should watch the road about ____ ahead of your vehicle.
One block
100 yards
One quarter mile ✓
One mile
Answer: C. One quarter mile
At highway speeds you should watch the road about one quarter mile ahead of your vehicle. The handbook says good drivers look at least 12 to 15 seconds ahead, which is the distance you will cover in that time. At lower speeds that works out to roughly one block, and at highway speeds it comes to about a quarter of a mile. Looking that far ahead gives you room to stop or change lanes without sudden moves, and the handbook notes that drivers who fall short of this may have to brake too hard or switch lanes too quickly.
4. One way to overcome the challenges of blind spots is to:
Drive faster than surrounding vehicles so no other drivers can pass you.
Drive in the left lane, allowing you to only worry about vehicles to your right.
Make frequent mirror checks and assess the positions of surrounding vehicles. ✓
Avoid using your mirrors.
Answer: C. Make frequent mirror checks and assess the positions of surrounding vehicles.
Make frequent mirror checks and keep track of where surrounding vehicles are, so you know when one has slipped into a blind spot. The handbook says you cannot see everything with your mirrors, since blind spots exist that they do not show. That is exactly why it tells you to check your mirrors regularly: to know where other vehicles are around you and to notice when one moves into a blind spot. Checking often keeps you aware of traffic on both sides and behind, which matters if you suddenly need to change lanes.
