Crackdown will outlaw drug driving

Lillian Groves was 14 when she was knocked down and the driver went on to serve just four months in jail.

The Prime Minister said it “simply can’t be right” that the laws were not in place to punish drug drivers properly.

Motorists under the influence of illegal substances can only currently be prosecuted for being behind the wheel if police can prove their driving has been impaired.

Mr Cameron said: “We want to do for drug driving what drink- driving laws have done for driving under the influence of alcohol.

“This week we’ll publish a new drug-driving offence so that driving under the influence of drugs itself is a crime, just like it is for drink driving.

“Lillian Groves’s family should be congratulated for their brave campaign. I hope now that something good can come out of their tragic loss.”

Under the crackdown, drug driving will become a specific offence. Offenders will face up to six months in jail and fine of up to £5,000 as well as an automatic driving ban of at least 12 months.
