Television and radio stations, outdoor billboards and online sites pumped up the message of the TAC's latest battle.

TAC Minister Tim Holding said the new education campaign sent a blunt warning to young road users by graphically depicting the dangers of driving under the influence of drugs.

The campaign tackles the effects of drug driving in an effort to reduce the death toll on state roads.

"This campaign specifically targets the high number of young men putting themselves and others at risk when driving on drugs," Mr Holding said.

"Driving on drugs is illegal, stupid and highly dangerous," he said.

About 20 per cent of drivers killed on Victorian roads test positive for amphetamine-type stimulants or cannabis.

Stimulant use is associated with a three-fold increase in risk of a crash, and is thought to encourage dangerous behaviour, including speeding.

A recent report from the National Drug and Alcohol Research Centre found 71 per cent of drug users had driven a motor vehicle in the last six months within an hour of taking drugs.

Of those reporting driving under the influence of drugs, 63 per cent admitted to using ecstasy, 65 per cent used amphetamine-type stimulants, and 63 per cent used cannabis.

Mr Holding said drug drivers recklessly put themselves and others at risk of serious injuries and death.

"Driving under the influence of drugs is dangerous because it makes you less alert, impairs your vision, reduces your co-ordination and prevents you from making the right decisions under pressure," Mr Holding said.

He said the campaign was part of the government's Arrive Alive strategy. "Our message is a simple one - if you drive on drugs, you're out of your mind," Mr Holding said.

Since testing began in December 2004, more than 62,000 random drug tests have caught 1059 drivers driving under the influence of drugs.

The current road toll is 184, compared with 185 at the same time last year.
