Reversing (also known as backing up) is the process of driving a vehicle in the reverse direction in order to maneuver. Rear view mirrors are standard equipment for this endeavor. Extremely large or luxury vehicles may have in addition technical aids such as backup cameras. Many industrial vehicles such as fork lifts automatically activate a warning beep whilst reversing.
In the UK lorries may be fitted with warning devices which repeatedly announce “This vehicle is reversing”, or the equivalent phrase in Welsh.
Reversing a vehicle can serve the purpose of changing lanes in traffic when a driver wishes to change to an adjacent lane but the destination lane is relatively jammed with vehicles (backed up). This is performed by driving in the reverse direction until the vehicle can move into the adjacent lane (or adjacent lanes) at the back of the queue in the next lane.
According to the Nigeria Highway Code
Before you reverse make sure that there are no pedestrians particularly children or handicapped persons or physical obstruction on the road behind you. Be especially careful about the ‘blind area’ behind you-that is,the part of the road which you cannot see from the driving seat,either through the mirror or by looking backwards.
DO NOT REVERSE: If you can’t see clearly behind,get someone to guide you when you reverse.Otherwise don’t.
Never reverse from a side road into a major road
WHILE REVERSING: Persons reversing are liable for any obstruction or accident which they might cause.
At night always put your headlight off while reversing.
