The backrider in a motorcycle is the person that rides behind the driver. They are also called riding in tandem to mean there are 2 persons in the motorcycle. With the social distancing requirement the backrider is not allowed anymore provided the 2 riders are directly related like a family.
With the rules that the authorities are imposing, the public gets confused. What is a family for a backrider? The driver and the backrider should be a couple. I don’t know how they can prove that relationship. Maybe make them kiss each other?
