Surrey and Sussex Police’s summer crackdown on drink and drug-drivers begins next week.

Operation Dragonfly is a year-round strategy, which targets offenders in a bid to prevent collisions and save lives on the roads across the two counties.

Officers will be carrying out dedicated patrols to identify motorists who break the law – and risk the lives of themselves and others.

Police made 170 arrests in Sussex as part of the operation in June 2015; 148 on suspicion of drink-driving and 22 on suspicion of drug-driving. This is compared to 143 the previous summer.

People in Sussex can text officers on 65999 with the details of people they suspect of drink or drug driving or visit www.operationcrackdown.co.uk.

You can also contact the independent charity Crimestoppers anonymously on 0800 555 111 (www.crimestoppers-uk.org).

If you know someone is driving while over the limit through drink or drugs, call 999.
