Stop completely at a red light

At a red light you may not proceed straight or turn left unless a separate green arrow permits it. Stop fully before the line even when the junction appears empty.

Yield to oncoming traffic when turning right

A right turn crosses oncoming lanes. Yield to straight and left-turning traffic, then check pedestrians and bicycles before completing the turn.

Pedestrians have priority at crossings

Slow when approaching an uncontrolled crossing. If someone is crossing or clearly intends to cross, stop before the line and give way.

STOP / 止まれ requires a full stop

The red triangular 止まれ sign and road marking both mean stop. The wheels must become fully stationary before the line, then check both directions.

Stop and check at railway crossings

Stop before every level crossing even when alarms are silent and barriers are raised. Check both ways, and never enter unless there is room to clear it.

Expressways, ETC and PA/SA

Choose an ETC or general lane as signed, slow at the gate and keep space. PA denotes a smaller parking area; SA usually adds food, toilets and fuel. Rest before fatigue sets in.

Japan strictly prohibits drink-driving and handheld phone use. Everyone must wear a seat belt and children under six need a child seat. Report every accident to police on 110 and the rental company.
