Driving forward is one thing, but backing up is a totally different situation requiring special care.
When you drive forward and know you will be backing your vehicle up, plan ahead. Pull forward and get your vehicle as straight as possible to making backing easier. Be sure your mirrors are clean and adjusted properly. Have a spotter assist you if possible. Back your vehicle slowly while checking both mirrors to see how you are progressing.
Don’t over-steer when backing trailers. Sometimes it only takes a small movement of the steering wheel to accomplish the movement you need. Over-steering may cause you to lose control.
Be aware of any overhead obstacles you could strike, especially if you’re driving a van or other tall vehicle. Compensate if you have something protruding out the side or over the back end of your vehicle. And, of course, be sure the path behind you is clear.
Safe, successful backing requires patience. Don’t be in a hurry.
Practice your backing skills when the opportunity arises and conditions are safe. Make yourself an expert no matter which direction you’re going.
