Can the Police test a driver for drugs?
Drug drivers may think that because they pass a test for alcohol they will be off the hook. This is not the case because the Police can also prosecute a driver who is unfit through drugs and there are various ways they can detect and prove the offence. One specific test the Police may use is the Field Impairment Assessment. It can be administered by trained officers at the roadside and is based on an observation of impairment, rather than a biological test.
