Question

DentroTest · Accepted Answer

Sign R-404, "Mandatory road for cars, except two-wheeled motorcycles", belongs to the group of mandatory signs and imposes on drivers of automobiles the duty to travel on the roadway at whose entrance it is placed; two-wheeled motorcycles and three-wheeled vehicles classed as motorcycles are excluded (Official Catalog of Traffic Signs, Royal Decree 465/2025). Under the General Vehicle Regulations, a bus is an automobile (a motor vehicle intended for the transport of people), so the driver is required to take that roadway and leave the road they were traveling on. It is neither a prohibition nor a mere optional possibility.
