1

Speed limit signs indicate:
  1. The average speed all drivers should match.
  2. The maximum or minimum speed legally allowed. ✓ Correct
  3. The speed to maintain for fuel efficiency.
  4. The suggested speed for new or inexperienced drivers only.

Correct answer: B. The maximum or minimum speed legally allowed.

Speed limit signs display the maximum legal speed allowed under ideal weather and traffic conditions. On some major highways, you will also see signs posting a minimum speed limit to prevent slow-moving vehicles from creating hazards.

2

On a New York State highway where there is no posted speed limit, the fastest you may legally drive is:
  1. 50 mph
  2. 55 mph ✓ Correct
  3. 60 mph
  4. 65 mph

Correct answer: B. 55 mph

In New York, the statewide default speed limit is 55 mph. If no speed limit signs are posted on a state highway, this is the legal maximum speed you may travel.

3

Unless otherwise posted, what is the speed limit in New York City?
  1. 25 mph ✓ Correct
  2. 15 mph
  3. 35 mph
  4. 20 mph

Correct answer: A. 25 mph

In New York City, the citywide default speed limit is 25 mph unless another limit is explicitly posted. This lower limit is mandated by law to ensure safety in densely populated urban areas.

4

When you are driving within the speed limit, you can be given a speeding ticket:
  1. If road or weather conditions require a slower speed. ✓ Correct
  2. Under no circumstances because it is always legal.
  3. Only if you are approaching a sharp curve in the road.
  4. Only if other drivers are going faster than you.

Correct answer: A. If road or weather conditions require a slower speed.

This is known as the Basic Speed Law. Even if the sign says 55 mph, driving that speed during a heavy rainstorm, thick fog, or in bumper-to-bumper traffic is considered unsafe. If a police officer determines your speed is "greater than is reasonable and prudent" for the conditions, you can be cited for speeding even if you are below the number on the sign.

5

Which of the following is a requirement of the Basic Speed Law?
  1. Always drive the speed limit, regardless of conditions.
  2. Never drive faster than is safe for current conditions. ✓ Correct
  3. Match your speed to that of your surrounding traffic.
  4. Reduce your speed only when weather conditions are poor.

Correct answer: B. Never drive faster than is safe for current conditions.

Basic Speed Law simply says you should never drive faster than what is safe given the current road, weather, and traffic conditions, whatever that speed happens to be.

6

A posted speed limit of 65 mph means you:
  1. Must always drive exactly 65 mph.
  2. May drive faster only if no other vehicles are present.
  3. May drive up to 65 mph under ideal conditions. ✓ Correct
  4. May drive up to 75 mph when passing a slower vehicle.

Correct answer: C. May drive up to 65 mph under ideal conditions.

The posted limit of 65 mph is the maximum you are allowed to drive under ideal conditions. If the road, weather, or traffic situation calls for it, you should be going slower.

7

The general speed restriction does not apply when:
  1. A different speed is posted by a sign. ✓ Correct
  2. Driving on a freeway late at night with little traffic.
  3. Road conditions are ideal and visibility is clear.
  4. Keeping up with faster traffic to avoid being a hazard.

Correct answer: A. A different speed is posted by a sign.

A posted sign showing a different speed limit overrides the general restriction for that specific road or zone.

8

Choose the incorrect option. The reaction distance length depends on:
  1. Human factor.
  2. Vehicle speed.
  3. Weather conditions. ✓ Correct

Correct answer: C. Weather conditions.

Weather conditions like rain, snow, or ice affect tire traction and influence braking distance. They do not change your reaction distance, which is the distance covered before the brakes are actually applied.

9

The higher your speed, the:
  1. Longer it takes to stop. ✓ Correct
  2. Shorter your braking distance.
  3. Same your braking distance remains.

Correct answer: A. Longer it takes to stop.

As your velocity increases, both your "thinking distance" (the time it takes to react) and your "braking distance" (the physical distance the car travels after hitting the brakes) grow significantly, requiring a much larger gap to safely stop.

10

The more loaded your vehicle is:
  1. The shorter it takes to stop safely.
  2. Vehicle load has no effect on stopping distance.
  3. The longer it takes to stop safely. ✓ Correct
  4. The better your tires grip the road, reducing stopping distance.

Correct answer: C. The longer it takes to stop safely.

A heavier load increases the vehicle's momentum, which directly extends the stopping distance needed to come to a safe halt.

11

The "2-second rule" recommends:
  1. Keeping a 2-second gap on highways only.
  2. Keeping at least a 2-second gap at 30 mph or less.
  3. Maintaining at least a 2-second gap. ✓ Correct
  4. Doubling your following distance only when passing.

Correct answer: C. Maintaining at least a 2-second gap.

The 2-second rule is a universal minimum following distance guideline that applies at all speeds and on all road types. In adverse conditions such as wet roads, poor visibility, or heavy traffic, the gap should be extended.

12

To prevent tailgating, you should:
  1. Follow the two-second rule. ✓ Correct
  2. Honk to make the driver ahead move faster.
  3. Keep a 100-foot gap.
  4. Stay close but keep your eyes on the road at all times.

Correct answer: A. Follow the two-second rule.

The "two-second rule" is a time-based measurement that automatically adjusts your following distance to your speed, ensuring you have enough space to react if the car in front stops suddenly.

13

Increase your following distance when you:
  1. Are being tailgated by another driver. ✓ Correct
  2. Pass a broken-down car on the shoulder.
  3. Prepare to turn left at the next intersection.

Correct answer: A. Are being tailgated by another driver.

Increasing your forward gap provides more room for gradual braking. This prevents the tailgater from rear-ending you if traffic stops suddenly, as you won't be forced to slam on your brakes.

14

Which of the following should you do if you are being followed by a tailgater?
  1. Change lanes and allow the tailgater to pass. ✓ Correct
  2. Tap the brakes to signal you are moving at a slower pace.
  3. Increase your speed to match the speed of the vehicle.

Correct answer: A. Change lanes and allow the tailgater to pass.

Moving to another lane is the safest way to resolve the situation. It removes the immediate hazard and allows the faster driver to proceed without further conflict or risk of a rear-end collision.

15

When driving with low-beam headlights in an unlit area, keep speed at:
  1. 40 mph or less
  2. 30 mph or less ✓ Correct
  3. 50 mph or less
  4. 60 mph or less

Correct answer: B. 30 mph or less

Low beams typically illuminate 150–200 feet. At 30 mph, your total stopping distance is roughly 100 feet, ensuring you can see, react, and stop safely within the lit area of the road ahead.

16

How far ahead do low beams typically illuminate?
  1. 100 feet
  2. 400 feet
  3. 200 feet ✓ Correct
  4. 500 feet

Correct answer: C. 200 feet

Standard low-beam headlights are designed to illuminate the road for approximately 200 feet ahead of the vehicle, which is roughly the stopping distance for a car traveling at 35–40 mph.

17

How far ahead do high beams usually illuminate?
  1. 400 feet ✓ Correct
  2. 800 feet
  3. 200 feet
  4. 1,000 feet

Correct answer: A. 400 feet

Standard high-beam headlights are designed to illuminate the road for about 350 to 400 feet ahead, providing enough visibility for a driver to see hazards at highway speeds.

18

You should leave more space in front when following a:
  1. Motorcycle ✓ Correct
  2. Station wagon
  3. Passenger vehicle
  4. Large truck or tractor-trailer

Correct answer: A. Motorcycle

Motorcycles can stop much faster than cars, and a minor bump that would be a "fender bender" between two cars can be fatal for a motorcyclist; extra space is required to give you time to react if they brake suddenly or hit a pothole.

19

If a vehicle is tailgating you, the safest way to prevent a collision is to:
  1. Speed up significantly to create a larger gap behind you.
  2. Gradually increase the following distance between you and the car in front. ✓ Correct
  3. Brake frequently to signal your intentions.
  4. Turn on your hazard lights to make your vehicle more visible.

Correct answer: B. Gradually increase the following distance between you and the car in front.

By increasing the space in front of you, you ensure that you can brake slowly and gently if needed. This gives the tailgater behind you more time to react and stop without hitting your rear bumper.

20

If you are being tailgated on a multi-lane highway, what is the safest and most effective action to take?
  1. Maintain the speed and change lanes if possible. ✓ Correct
  2. Stay in your lane and turn on your hazard lights.
  3. Move to the left lane to get out of the way.
  4. Maintain your lane and slow down to force them to change lanes.

Correct answer: A. Maintain the speed and change lanes if possible.

By signaling clearly and moving into another lane (usually to the right), you allow the tailgater to pass safely; this immediately removes the danger to your rear bumper and de-escalates the situation.

21

You are allowed to drive at the maximum posted speed limit only:
  1. On freeways and highways only.
  2. When conditions are ideal. ✓ Correct
  3. During daylight hours only.
  4. When the weather is clear, but heavy traffic forces you to weave

Correct answer: B. When conditions are ideal.

The posted speed limit is a legal maximum designed for perfect weather and road surfaces; if it is raining, foggy, or the road is covered in gravel, you are legally required to drive slower than the sign allows.

22

When driving at night on a poorly lit street, you should:
  1. Use high beams constantly to spot pedestrians early.
  2. Focus on the area directly in front of your bumper.
  3. Drive slowly enough to stop within your headlights' range. ✓ Correct
  4. Speed up to pass through the dark area quickly.

Correct answer: C. Drive slowly enough to stop within your headlights' range.

If a hazard appears at the very edge of your headlight beam and you are traveling too fast to stop before hitting it, you are "overdriving your headlights" and essentially driving blind.

23

Check your rearview mirrors:
  1. Often to monitor traffic behind you. ✓ Correct
  2. Only when changing lanes or parking.
  3. Frequently, staring for several seconds at a time.
  4. Every few minutes to stay aware of traffic behind you.

Correct answer: A. Often to monitor traffic behind you.

Checking your mirrors frequently and consistently keeps you aware of how traffic behind you is developing, giving you time to react to vehicles that are closing in, braking, or changing lanes.

24

One of the rules of defensive driving is:
  1. Look straight ahead as you drive.
  2. Stay alert and keep your eyes moving. ✓ Correct
  3. Expect that other drivers will make up for your errors.
  4. Be confident that you can avoid danger at the last minute.

Correct answer: B. Stay alert and keep your eyes moving.

A core tenet of defensive driving is to keep your eyes moving, which also includes looking straight ahead, scanning the sides, and checking your mirrors every 2 to 5 seconds. This prevents your eyes from fixing on one object and ensures you are always aware of the changing traffic environment.

25

What should you do if a vehicle merges in front of you too closely?
  1. Brake firmly to restore your following distance
  2. Take your foot off the accelerator to create space ✓ Correct
  3. Change lanes as soon as it is safe to do so
  4. Maintain your speed and use the two-second rule

Correct answer: B. Take your foot off the accelerator to create space

That is exactly right. Easing your foot off the accelerator allows your vehicle to slow gradually and naturally, restoring a safe following distance without any sudden movements that could startle the drivers behind you.
