The red car is also letting their passenger out on-road. It is extremely unsafe for passengers to exit a vehicle in traffic especially as motorcycle and bicycle riders can legally move through stationary traffic. It is also offence for a passenger to remove their seatbelt on-road. If the passenger is under 16 the driver of the vehicle will also be committing an offence.
The driver of a vehicle (except a bus) must not drive (be in control of) a vehicle with a passenger if any part of the passenger’s body is outside a window or door of the vehicle. Driving in these circumstance includes stationary but not parked or stopped at a permitted location.
It’s also important to remember that vehicles cannot stop on a pedestrian crossing, 20 metres before or 10 metres after a crossing unless a parking sign states that vehicles are permitted to stop or park in that area.
Don’t be the red car, pull over safely in a designated area to let passengers out.
