Overview
Defensive driving means expecting other drivers to make mistakes and leaving yourself room to react. This chapter covers following distance, speed, using headlights, driving at night and in bad weather, and handling problems such as skids.
Keep at least a two-second gap behind the vehicle ahead, and make it longer in rain, snow, fog, or darkness. To check, pick a fixed object and count the seconds after the car ahead passes it. New York's maximum speed limit is 55 mph unless signs show a different limit, but you must drive slower when conditions call for it.
Headlights must be on from one-half hour after sunset to one-half hour before sunrise, when visibility is less than 1,000 feet, and whenever you use your windshield wipers because of the weather. Switch to low beams within 500 feet of an oncoming vehicle and within 200 feet of a vehicle you are following. On wet roads your tires can ride up on a layer of water, so slow down. If your car skids, take your foot off the gas and steer in the direction you want the front of the car to go.
Key concepts
Two-second rule
Stay at least two seconds behind the vehicle ahead. When its rear passes a fixed point like a sign, count; if you reach that point before you finish two seconds, you are too close. Leave more time in bad weather or at night.
Memory tipCount "one thousand one, one thousand two" in good conditions, more in bad.
Speed limit
Unless signs show a different limit, the maximum speed in New York State is 55 mph. Even below the limit, you must slow down when traffic, weather, or road conditions make the posted speed unsafe.
Memory tip55 is the top unless posted. Conditions can make the safe speed lower.

When to use headlights
Turn on your headlights from one-half hour after sunset to one-half hour before sunrise, when you cannot see clearly for 1,000 feet, and any time you use your windshield wipers because of rain, snow, or sleet.
Memory tipWipers on means headlights on.

Dimming high beams
Switch from high beams to low beams within 500 feet of a vehicle coming toward you and within 200 feet of a vehicle you are following, so you do not blind other drivers.

Hydroplaning
On wet roads, especially at higher speeds, your tires can ride on top of a thin layer of water and lose contact with the road. Slow down in rain, and if it happens, ease off the gas and avoid braking hard or turning sharply.
Memory tipRain plus speed equals less grip. Slow down before it happens.
Handling a skid
If your car starts to skid, take your foot off the gas and steer in the direction you want the front of the car to go. Avoid slamming on the brakes.
Memory tipLook and steer where you want to go.

3 sample questions
Verified practice questions from this unit.
Question 1. What is the smallest safe following distance in good conditions?
- ① At least two seconds behind the car ahead
- ② At least one second behind the car ahead
- ③ One car length, no matter the speed
- ④ Close enough to read its license plate
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① At least two seconds behind the car ahead
Key point: Keep at least a two-second following distance
Keep at least two seconds between you and the vehicle ahead in good conditions. Leave more space in rain, snow, at night, or behind large vehicles.
Wrong choices
- At least one second behind the car ahead: One second is not enough time to react and stop.
- One car length, no matter the speed: Car lengths do not change with speed. Use time instead.
- Close enough to read its license plate: That is often much too close.
Question 2. You are using high beams at night. When must you switch to low beams for oncoming traffic?
- ① Within 500 feet of an oncoming vehicle
- ② Within 100 feet of an oncoming vehicle
- ③ Within 1,000 feet of an oncoming vehicle
- ④ Only if the other driver flashes their lights
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① Within 500 feet of an oncoming vehicle
Key point: Dim high beams within 500 feet of oncoming cars
Dim your high beams within 500 feet of an oncoming vehicle so you do not blind the other driver.
Wrong choices
- Within 100 feet of an oncoming vehicle: 100 feet is too late. The other driver would already be blinded.
- Within 1,000 feet of an oncoming vehicle: You may dim earlier, but the rule is 500 feet.
- Only if the other driver flashes their lights: You must dim even if they do not flash.
Question 3. Unless a sign shows a different limit, what is the maximum speed limit in New York State?
- ① 65 mph
- ② 50 mph
- ③ 70 mph
- ④ 55 mph
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ 55 mph
Key point: NY default speed limit is 55 mph
In New York State, the speed limit is 55 mph unless a sign shows another limit. Always drive slower when conditions are poor.
Wrong choices
- 65 mph: 65 mph is allowed only where it is posted.
- 50 mph: 50 mph is not the general state limit.
- 70 mph: New York does not have a 70 mph speed limit.
