Leaving the vehicle: revision notes

Where and how you leave a large vehicle matters for safety, security and the law.

  • Before leaving the cab: apply the parking brake, switch off the engine, remove the key and lock up. Never leave the engine running while unattended.
  • Opening the door: check mirrors and look round for cyclists before opening a door on the traffic side.
  • Lights at night: parking lights are needed on roads with limits over 30 mph. Vehicles over 2,500 kg must not be left on a road at night without lights, and you must not park facing against the traffic flow unless in a recognised space.
  • Where not to park: near level crossings, school entrances, bus stops or anywhere that causes an obstruction.
  • Lorries over 7.5 tonnes must not park on verges or pavements without police permission, except when essential for loading, and then never unattended.

Bus drivers should walk through the bus at the end of a shift to check no passengers are left on board.
