To ask the Secretary of State for Transport, whether the Government plans to review trends in the of levels of prosecution of drug driving.

The Government is committed to tackling drivers under the influence of drugs and ensuring that all such drivers are caught and punished.

We have a combined approach of tough penalties and rigorous enforcement, along with our highly respected and effective THINK! Campaigns.

The Government is progressing a three-year review into roads policing and traffic enforcement. The Department for Transport will be looking at this with the Home Office, Association of Police and Crime Commissioners and the National Police Chiefs’ Council. We aim to identify ways of increasing capability and capacity across a range of agencies. This review will not only highlight where police forces are doing good work, it will show what more can be done to improve road safety.
