Driving while impaired by a drug is an offence. Many driver fatalities are affected by medicines and/or illegal drugs, which is why there is zero tolerance regarding drugs and driving.
Drug effects include impaireddriving skills by affecting your vision, reflexes, alertness, coordination etc., and behavioural change such as taking risks that you wouldn’t take normally. This endangers yourself, your passengers, and other road users.
Cannabis, ecstasy, speed and heroin are examples of illegal drugs that can affect your driving. Illegal drugs increase the crash risk and make you a danger to all road users.
Medicines may increase the risk of crashing by affecting your concentration, coordination, mood and reaction time. Examples of such medicines:
Ask your doctor or pharmacist for advice on how any new medicines may affect your driving. While on medication:
If your medicine affects your reflexes, your driving ability, or your ability to concentrate - contact your doctor or pharmacist. Refrain from driving if you aren’t sure how a new drug may affect you.
Police are at liberty to undertake roadside saliva testing to detect speed, ecstasy and cannabis use. You can be tested at any time, anywhere.
If suspected of using drugs, a police officer can require you to provide blood for a drug test.
Blood samples are always taken if a person is sent to the hospital after a crash and may be tested for drugs.
Mixing medications, drugs or alcohol can be very dangerous, and might even be deadly. Combining drugs with alcohol will impair you much more than either one on its own.
