Drug driving prohibition notices
WA Police Force will issue drivers who test positive for specified drugs (Cannabis, Ecstasy or Meth) or refuse a roadside drug test with a prohibition notice which bans them from driving for 24 hours.
Breaching the prohibition notice is an offence. Police may issue an infringement notice with a penalty of $600.
Drug driving penalties
Police have the power to stop drivers suspected of driving while impaired by any drug.
Those found with specified drugs (Cannabis, Ecstasy or Meth) in their oral fluid can be charged with the offence of Driving with Specified Drugs in Oral Fluid.Table 1: Drug driving penalties
The more serious offence of Drug Impaired Driving under the Influence of Drugs applies to drivers found to be so impaired by either prescription or illicit drugs that they are not capable of proper control of a vehicle.
This applies where police have evidence of suspicious or erratic driving behaviour and where that suspicion is confirmed following a driver assessment and/or blood tests.Table 2: Driving under the influence of drugs penalties
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.
