There are no specific legislative requirements that an individual wears shoes whilst driving a car in South Australia. However, drivers should be cautious in driving barefoot as this can count as a factor in the event of a crash. A driver must have proper control of a vehicle so if an accident does occur, whether the driver’s (lack of) footwear played a role in the accident may be investigated. You can also get caught by this law by driving while having an animal or person on your lap – in essence, anything that may cause a distraction.
