Final answer:
The easiest and safest backing maneuver is straight-line backing.
Step-by-step explanation:
The easiest and safest backing maneuver is straight-line backing. This maneuver involves backing up the vehicle in a straight line without any turns or curves. It is considered easier and safer because it eliminates the need for complex maneuvers and reduces the risk of colliding with obstacles or other vehicles.
Straight-line backing is especially useful in situations where there is ample space and limited obstacles, such as an empty parking lot or a straight driveway. It allows the driver to have better control and visibility while backing up.
