Other effects of alcohol or drug driving

Must hold probationary licence

Whether a person serves the full disqualification period or resumes driving using an alcohol interlock device, the person must hold a probationary licence for at least one year (see probationary licence).

Insurance exclusions

The fact that a driver has been convicted of driving with prescribed alcohol or drugs cannot be taken to show that they were under the influence and incapable of exercising effective control of the motor vehicle at the time and any insurance policy that attempts to limit or exclude liability on the basis of such a conviction is void [Road Traffic Act 1961 (SA) s 47C and Wood v Zurich Aust Insurance Ltd [1997] SADC 3604, see also Insurance. Most insurance policies covering damage arising from motor vehicle accidents do, however, exclude the liability of the insurer if the driver was under the influence of alcohol or drugs at the time of the accident.

The South Australian compulory third party insurance policy currently requires the driver to refrain from driving while so much under the influence of alcohol or drugs that they are incapable of exercising effective control of the vehicle and to refrain from driving while there is present in his or her blood a concentration of .10 grams or more of alcohol in 100 mL of their blood. See the policy on the CTP Insurance Regulator's website here.
