The next time you are backing out of your driveway or a parking stall, take a second and look all the way around your vehicle. Look for obstructions, others backing out, and oncoming traffic. Improper backing has traditionally been a leading cause of traffic accidents.
Standard Traffic Ordinance (STO) 117, Limitations on Backing, states the driver of a vehicle shall not back unless such movement can be made safely and without interfering with other traffic. The driver of a vehicle shall not back upon any shoulder or roadway of any controlled-access highway.
For your safety and the safety of others, make it a habit, to always check your surroundings before making any movements in a vehicle, especially when backing.
