What does the Congolese Highway Code say about opening a vehicle's doors?

1. A door must not be opened, left open, or used to get out, without first making sure this creates no danger for other road users
2. Doors may be opened freely as long as the vehicle is stationary
3. Only the driver's door is restricted; passenger doors are unregulated
4. Doors may be left standing open while parked, to ventilate the cabin in hot weather
