Reservation signs are rectangular, blue and white. They tell you that a lane, part of the roadway or a parking area is reserved for the exclusive use of a specific class of vehicle. The letter R means a roadway or lane reservation; the letter P means a parking reservation.
Roadway reservations show the vehicle class at the top (bus, taxi, bicycle, or a dotted oval for an authorised public transport operator's logo) and a yellow dashed line showing which side is reserved: the lane to the left of the line, the lane to the right of the line, or a curved line marking the start of the reserved lane. A panel with a logo, a bus and numbered bays is a reserved bus stop zone. A yellow version means the reservation is temporary.
Parking reservations range from plain P (area reserved for parking), P with a vehicle class, disabled persons parking (reserved at all times for vehicles carrying a person with a disability), 60 min (maximum duration), CD (authorised diplomatic vehicles), a police badge, to temporary yellow versions. Plates beneath may add conditions, for example a parking meter symbol (pay a fee) or times.
A red cross over a reservation sign (de-restriction) means the reservation has ended and all vehicles may now use the lane.
Do not confuse a blue rectangle with R (lane reserved) with a blue disc (command for that class to use the road) or a red-barred disc (that class prohibited).
