Nearly 30,000 motorists have been banned for drug-driving since 2015

Drug-driving became an offence in March 2015, and since then nearly 30,000 drivers have been banned from driving after taking illegal substances.

Younger drivers are not the only ones testing positive for drugs, as more than 60 pensioners were also banned.

The Department for Transport analysis also shows that one in six drivers killed in car crashes had taken illegal substances.
