15. Bus lane
A bus lane is a traffic lane reserved primarily for buses or other authorised public-transport vehicles. It is intended to improve the reliability and flow of public transport by allowing authorised vehicles to avoid general traffic congestion.
Other road users, such as taxis, cyclists, motorcycles or vehicles carrying several occupants, may also be permitted when signs expressly allow them. The operating hours, permitted vehicles, direction of travel and rules for entering or crossing the lane depend on local traffic signs and regulations.

Which vehicles may use a bus lane in the United States?
US bus lanes are controlled by state and local rules and signs. In California, bus-only lane indications restrict ordinary driving; read the actual signs and any permitted turning arrangement.

Does bus-lane access also allow stopping or parking in the United States?
A locally permitted turn across or from a bus lane does not authorise parking. Read the lane and kerbside controls and leave designated bus stops clear.
