You and a car two lanes away both appear to be moving toward the lane between you. What should you do?
Correct answer: Delay your move until that lane is safely available.
Check the target lane and nearby lanes for vehicles moving into the same space. Signaling does not reserve a lane.

What makes up total stopping distance after a driver notices a hazard?
Correct answer: The distance traveled while reacting plus the distance needed to brake.
You travel before the brakes begin slowing the car as well as during braking. Speed, road surface, tires and attention affect the space needed.

A driver is following too closely. What is the safest response when an opportunity develops?
Correct answer: Allow the driver to pass safely and keep your own actions predictable.
Avoid escalating a tailgating conflict. Let the driver go by safely rather than brake-checking or speeding.

You are already on an interstate and notice a car approaching the end of an entrance ramp. A lane change away from it is safe and permitted. Which action can help traffic merge smoothly?
Correct answer: Signal and move over safely to make room.
The guide recommends making room for entering vehicles when a lane change is safe. Check surrounding traffic first; cooperation does not justify an abrupt move or stopping a through lane.

A wide farm vehicle ahead slows near an unmarked field entrance. What is the best response?
Correct answer: Stay back and allow room for an unexpected or wide turn.
Farm equipment may turn into field entrances that are difficult to see. Its width and turning path require patience and extra space.

A heavily loaded truck accelerates slowly away from a stop. How should you respond behind it?
Correct answer: Be patient and keep an adequate following gap.
Large vehicles need time to gain speed because of their weight. Pressuring the driver does not create a safe passing opportunity.

Before turning across the path of an approaching tractor-trailer, what mistake should you avoid?
Correct answer: Assuming its large appearance means it is moving slowly.
The size of a truck can mislead your estimate of its approach. If there is not a clearly safe gap, wait rather than forcing the truck to brake.

On a narrow road, a cyclist appears unaware that you are behind. If a warning is needed, how should you use your horn?
Correct answer: Give a brief, gentle tap without startling the rider.
A short warning may alert the rider to your presence. It does not create extra road width or justify intimidating the cyclist into an unsafe position.

Why should you search carefully for bicycles near the road edge at night?
Correct answer: They can be hard to see, especially in glare from approaching traffic.
Do not assume the absence of a car-sized light means the path is empty. A rider can be difficult to distinguish among headlights and roadside shadows.

Frost covers your side windows and snow covers the rear lights. What should you do before moving?
Correct answer: Clear the windows and lights so you can see and be seen.
All-around visibility and visible lights matter. Remove obstructions before driving rather than depending on speed or the defroster to solve the problem later.

You are adjusting the driver’s head restraint. Where should its center be?
Correct answer: At about the center of the back of your head.
Position the head restraint to support the back of the head. A low setting behind the neck does not provide the intended protection.

Where should the lap portion of your belt fit?
Correct answer: Snugly across the hips and pelvis, not high across the abdomen.
A snug, low lap belt places forces on the pelvis. Everyone should be properly buckled before the vehicle moves.
