Is it necessary for both rear wipers to function if a vehicle is equipped with them?

The correct answer indicates that it is acceptable for only one rear wiper to be functioning when a vehicle is equipped with them. This is based on the understanding that while having both rear wipers working is ideal for optimal visibility in adverse weather conditions, traffic safety regulations do not typically mandate that both must be operational. In many cases, a vehicle can still effectively clear water or debris from the rear window with just one operational wiper.

The performance and condition of a single wiper can still maintain sufficient visibility for the driver. This is particularly relevant for certain vehicle designs that allow for effective functioning with only one rear wiper, ensuring that safety is maintained even when one wiper is out of commission. Regular maintenance, however, is advised to ensure both wipers are in working order to provide the best safety standards.
