听力原文： Victoria's Police Minister, Andre Haermeyer, said that a third of drivers killed

on the state's roads last year tested positive for drugs other than alcohol. He said the roadside cheeks were a world first. They'll target people who've used cannabis and methamphetamines at nightclubs and dance parties. Truck drivers who take drugs to stay awake to meet deadlines will also face scrutiny. Drivers will be asked to place a small absorbent pad on their tongues for a few seconds.

The screening of saliva won't detect prescription drugs or medication such as cold or flu tablets. Drivers testing positive will then be required to give a second sample, which will be sent to a laboratory. Those found to have used illegal substances will be fined and could lose their licences. An Australian survey recently revealed that one in four men under the age of twenty-five said they had driven a car after taking an illegal drug.

A．They will be fined.
