The soon-to-be-introduced roadside testing for impairment from drug-taking is quite extraordinary. I don't accept what the police are saying.
"If someone is tired or has a medical condition they won't exhibit the same signs as someone who is under the influence of an illegal drug."
Here's just one of the tests;
MOTOR SKILLS TEST:
A driver must maintain his balance while standing upright, with his hands at his sides, head tilted back and eyes closed.
But be assured,
Random tests will not be conducted but if police believe a driver is impaired they must initiate a drug test.
For now but you can bet that will be the next step.
But it's how they justify these things that really rankles. The road toll has come down significantly so that won't work as a reason.
Ministry of Transport figures showed drugs were suspected in 36 crashes in the year to December 31, 2005. Drugs were proven in three whereas alcohol was suspected in 383 crashes.
The evidence of drug-use causing accidents isn't compelling.
So the agent of the state sets an arbitrary target road toll, 300 by 2010, and then complains about looking like we are not going to reach it.
