Drink driving doesn't just harm the driver - passengers and other road users are often involved in alcohol-related road deaths and injuries.
For every 100 alcohol or drug-impaired drivers or riders who die in road crashes, 47 of their passengers and 16 sober road users die with them.
The risk of crashing increases with the amount of alcohol in the blood at the time of driving. Road traffic crashes involving alcohol are more likely to result in death or severe injuries.
The number of convicted drink-drive offences has declined in recent years. Despite the downward trend, the number of repeat or multiple offenders remains high.
