# Explanation
When the vehicle is stopped, occupants should enter and exit **on the side closest to the pavement or shoulder** to avoid interference with passing traffic. This general rule provides greater safety, as it minimises the risk of accidents with other vehicles. Exiting on the side opposite to traffic would unnecessarily expose passengers to danger.
