The Transport Advisory Committee has endorsed the Government's proposed zero-tolerance policy on drug-driving.

Committee chairman Teresa Cheng said today members backed the plan to crackdown on drivers abusing heroin, ketamine, ice, cannabis, cocaine and ecstasy. Under the proposal a driver commits an offence when their body has any concentration of these drugs.

"The zero-tolerance approach should help send a clear message of no drug driving to the community, achieving maximum deterrent effect for the sake of road safety," Ms Cheng said.

They endorsed the Government's proposed introduction of impairment tests so Police can establish reasonable suspicion in drug-driving cases. The test is widely used abroad, with an accuracy rate of 95% in the UK and Australia.

Members advised that any rapid oral fluid test should be accurate and able to test ketamine, which is the drug taken in 90% of drug arrests in Hong Kong.
