如何 Back Up Safely
Reversing your vehicle in a straight line under control while watching for people and objects behind you.
分步操作
- Before you get in, check behind the vehicle for children, pedestrians, and objects — a backup camera does not show everything low or to the sides.
- Press the brake, shift into reverse, and release the parking brake.
- Turn your body and look back over your right shoulder through the rear window; use mirrors and the camera only as extra help, not instead of looking.
- Back up slowly, steering with small movements — turn the wheel toward the direction you want the rear of the car to go — and keep glancing to the front and sides.
- Stop right away if anyone or anything comes near, and don't back up farther or faster than you need to.
考官看什么
That you look back over your shoulder (not only at the mirror or camera), keep your speed slow and controlled, stay in a straight line or your lane, and check all around while reversing.
常见失分
Relying only on mirrors or the backup camera, backing up too fast, not checking behind the car first, and steering too much so the car weaves.
什么时候会用到
Leaving parking spaces and driveways, and a graded part of many road tests — often backing straight for about three car lengths while staying within about three feet of the curb.
