Traffic Signs

What does the S-51a road sign mean?

Question image: What does the S-51a road sign mean?
  • A Fork on a three-lane carriageway
  • Lane reserved for high-occupancy vehicles or specific vehicle types
  • C Fork of two lanes to the left on a four-lane carriageway
  • D Fork of two lanes to the right on a four-lane carriageway

Why this is the correct answer

Indicates a lane reserved exclusively for certain types of vehicles (buses, motorcycles, three-wheeled vehicles assimilated to motorcycles, taxis, cycles, etc.). The symbol of the authorised vehicle type or types will be shown on the sign. On sections where the longitudinal lane marking is a broken line, use of the lane by other vehicles is permitted only to perform a manoeuvre other than stopping, parking, U-turning or overtaking, and priority must always be given to vehicles authorised to use this lane.
