Driving under the influence of drugs is dangerous as it can affect driving ability. With side effects such as slower reaction times, distorted perceptions of speed and distance and reduced concentration and coordination, why would you risk it?
From 1 January 2007 to 31 December 2011, alcohol and other drug use were identified as a factor in 512 deaths on Queensland roads, or 33.3 per cent of the Queensland road toll†.
Random roadside drug testing
There is zero tolerance for driving under the influence of illegal drugs. Police conduct random roadside drug tests to detect any presence of:
- THC (delta-9-tetrahydrocannibinol) – the active ingredient in cannabis/marijuana
- Methylamphetamine – also known as speed and ice
- MDMA (3, 4-methylenedioxymethamphetamine) – the active ingredient in ecstasy.
These drugs can be detected in a simple saliva test.
A first offence carries a penalty of up to $1540 and you could be disqualified from driving for up to 9 months.
More information on roadside drug driver testing and how driving is affected by other medications (including over-the-counter drugs and prescription medications) is available in the Drug driving fact sheet.
Mixing drugs with other drugs or alcohol can seriously affect your health and your ability to drive safely. You may not feel intoxicated when in fact you could be over the limit.
- Never drive after taking illegal drugs.
- Never drive after taking prescribed or over-the-counter medications that could affect your driving.
- If you take any drug and you are unsure how it will affect your ability to drive, don't drive. Use public transport, ask someone else to drive or catch a taxi.
