New York DMV Permit Written TestSafe Driving PracticesHard
A driver is preparing to drive their vehicle after it has been parked overnight in freezing temperatures. What is a crucial vehicle maintenance check that should be performed before driving?
- ACheck the spare tire pressure.
- BCheck the tire pressure, as cold weather can reduce it.
- CVerify the windshield wiper fluid level.
- DInspect the air filter for debris.
Show answer & explanationAnswer & explanation
Correct answer: B. Check the tire pressure, as cold weather can reduce it.
Cold weather causes the air in tires to contract, leading to a drop in tire pressure. Underinflated tires reduce fuel efficiency, affect handling, and increase the risk of a blowout. Checking and adjusting tire pressure is critical for safety in freezing conditions.
Why the other options are wrong
- A. Checking the spare tire is good practice, but the tires currently on the vehicle are the immediate concern for safe driving.
- C. Wiper fluid level is important, but low pressure in tires directly affects vehicle control and safety immediately.
- D. While important, an air filter inspection is not specifically critical *before driving* after freezing temperatures.
Cold Weather Tire Pressure
Cold temperatures reduce tire pressure, requiring drivers to check and inflate tires to recommended levels for safety and performance.
- Air contracts in cold, lowering pressure.
- Underinflated tires are dangerous.
- Check pressure with a gauge when tires are cold.
Memory trick: Cold outside? Tires need a check, or you'll be on the wreck!
