An advertising campaign warning of the risks of driving after taking drugs is being launched in England and Wales.
A TV ad will warn motorists that police can spot signs someone is under the influence of drugs if they are stopped.
The Department for Transport says that one in 10 young male drivers admits drug driving and education is crucial.
Road safety charity Brake has welcomed the £2.3m campaign but says it is more important for ministers to approve a breathalyser-style drug-testing device.
