Worn tires lengthen stopping distances, hinder turning, and invite hydroplaning and flats.
9. Who bears responsibility for making sure a vehicle is safe to drive?
- The driver
- The mechanic
- The DMV

Answer: A — The driver
The driver is responsible for the vehicle being safe, since a poorly kept one costs more, can break down or crash, and can earn a citation.

Drivers should look directly over the shoulder through the rear window while backing, using mirrors and camera only as extras since mirrors miss the area right behind the car.
15. Why should a driver check behind the car before getting in to back up?
