A bus lane is a lane reserved primarily for buses or other authorised public-transport vehicles. Its purpose is to help public transport move efficiently through traffic.

A bus lane may be identified by a bus-lane sign, lane markings, coloured surfacing or the word BUS painted on the road. The markings and colours differ between countries.

No. A bus lane forms part of a wider road arrangement, while a bus-only road may reserve the entire road for buses and other authorised users.

Buses operating authorised or scheduled services may normally use it. Other vehicles may enter only when the traffic signs or local regulations expressly permit them.

This depends on local law and the signs displayed. Some bus lanes permit licensed taxis, while others are reserved exclusively for buses.

Cyclists may use a bus lane where signs or local law permit them. They should remain alert for large vehicles, stops, passengers and buses moving towards the kerb.

Only where motorcycles are expressly permitted. Permission may apply to all motorcycles, particular times or specific bus lanes.

Yes. A sign may show days or hours during which the restriction applies. Outside those periods, the lane may become available to general traffic, subject to the local rules.

Not necessarily. The normal road or posted speed limit generally applies unless a separate restriction is displayed.

Some countries allow drivers to enter a bus lane shortly before a junction to make a turn. Drivers must follow the lane markings and enter only at the point where local rules permit it.

Usually, where necessary and permitted. A driver may need to cross it at an intersection or to enter or leave a property, parking area or side road. The driver must check carefully for buses, cyclists and other authorised users.

No. An unauthorised driver may not use the bus lane simply to overtake a queue or reach the front of traffic.

Stopping and parking are normally prohibited unless a sign or marked bay expressly permits them. A stopped vehicle can obstruct buses and force authorised lane users into general traffic.

Not universally. Some countries require drivers to allow a signalling bus to leave a stop, particularly inside built-up areas. Elsewhere, ordinary merging rules apply.

No. Traffic lights, priority signs and the ordinary intersection rules continue to apply unless special public-transport signals indicate otherwise.

Yes. A contraflow bus lane may carry authorised vehicles in the opposite direction from nearby general traffic. Drivers and pedestrians should check both directions before crossing.

Some countries use separate lights or symbols for public-transport vehicles. Only drivers authorised to use that lane should follow those signals, while other traffic follows its own lights.

Check mirrors and blind spots and look for buses, taxis, cyclists, motorcycles or other authorised vehicles. Their lane may be moving even when general traffic is stationary.

It may end at a sign, a change in road markings, an intersection or the end of its stated operating period. Drivers should follow the lane arrows and merge safely where required.
