Prescription drugs and driving

Prescription drug misuse and a lack of awareness of the side effects that some medications have on driving, can lead to road trauma on WA roads.
Using prescription, over-the-counter medications and multiple drug use (using a combination of drugs) while driving can sometimes cause side effects and can reduce mental or physical abilities.
Extreme and varied effects such as dramatically slowed reaction times, visual distortion, inability to judge speeds and distances, and risk taking, can increase risk of crash.

If you’re on any prescribed medication it is imperative you understand the impact on your driving, including how to take it and the consequences of what happens if they do not administer the medication in the correct manner.  

For more information, read medicines & driving and speak to your health care professional.
