Road Safety Commission Acting Commissioner Kim Papalia said there was a correlation between people killed or seriously injured on the roads and those with illicit drugs in their system at the time of the accident.
�We have seen that 23 per cent of those injured or killed have registered with illicit substances in their system in the past two years and we are concerned that this is leading to an increase in avoidable fatalities on the road,� he said.
�Law was enacted in WA in 1971 to make it illegal not to wear a seatbelt and in the past two years we have seen high-risk behaviour by people in cars and also in drug use.
�Generally the risk-taking behaviour goes together (with drug taking).�
Acting Police Traffic Superintendent Ian Clarke said the increase in the number of people on the roads not wearing seatbelts was causing great concern to traffic police.
�We are seeing a marked increase across the state (of people wearing) no restraints and we will come down very hard on those not taking responsibility,� he said.
