[McWeston]

Seating etiquette for a five-seater sedan is as follows: 1. When the owner is driving: The seating order should be: front passenger seat, rear right seat, rear left seat, rear middle seat. 2. When a professional driver is driving: The seating order should be: rear right seat, rear left seat, rear middle seat, front passenger seat. 3. When there is a leader present: The front passenger seat is generally called the attendant seat, usually occupied by assistants, interpreters, security personnel, etc. Leaders sit in the rear seats. 4. Private car seating arrangement principles: The rear seats should be given to guests, leaders, or "those with relatively distant relationships"; respect the guest's personal choice of seating, wherever the guest sits is considered the seat of honor; if sitting in the front passenger seat, it is best not to sleep as a sign of respect.
