As a vehicle is defined in section 5 of the Road Traffic Act 1961 (SA) to include a bicycle, persons riding a bicycle can be charged with certain offences under this Act if the offence applies to vehicles.

A person riding a bicycle can be charged with 'driving' a bicycle or attempting to put a bicycle in motion while so much under the influence of alcohol or drugs as to be incapable of exercising effective control of the bicycle [Road Traffic Act 1961 (SA) s 47(1)].

Maximum penalty: a fine of $500, and demerit points may also apply [s 47(1)(b)].

However some alcohol and drug driving offences only apply to motor vehicles- see section 5 of the Road Traffic Act 1961 (SA) for the definition of motor vehicle.
