Si por causa de una avería nos vemos obligados a empujar la motocicleta, se nos considerará...

If, because of a breakdown, we have to push our motorcycle, we are considered a driver. This is because, by definition, a driver is a person who operates the steering or is in control of a vehicle, or who is in charge of one or more animals. In this case, although we are pushing the motorcycle instead of riding it normally, we are still responsible for the vehicle and in control of its steering. So we are considered drivers in this situation.
