Bus lanes are specifically covered in the Highway Code with Rule 141 which outline how they can be identified, usually road markings and signs.
It continues: “Unless otherwise indicated, you should not drive in a bus lane during its period of operation.
“You may enter a bus lane to stop, to load or unload where this is not prohibited.”
Rule 32 addresses pedestrians and their use of buses, ensuring people know to only get on or off a bus when it is stopped.
