Thirty-one drivers out of the 209 were prosecuted after they were involved in collisions.

“This campaign is all about getting the message across that drinking or taking drugs and driving is irresponsible and won’t be tolerated,” said Chief Inspector Andy Male, Head of Roads Policing.

“We continually need to stress to as many motorists as possible that this kind of behaviour can result in death and serious injury. Most people who were stopped were receptive to our awareness campaign but the results show that over 200 people were still prepared to take a risk.

“Even small amounts of alcohol can impair a driver’s ability enough to cause an accident. If caught and convicted motorists will lose their licence and probably their livelihoods.

“Police officers patrolling the roads will stop any driver who does not appear to be in control of their vehicle.”

Eleven people were arrested out of 24 motorists suspected of driving under the influence of drugs. This compares to respective figures of 12 and 27 in June 2008.

The percentage of drivers who refused, failed or provided positive breath tests was 1.82 compared with 3.67 last year.

The campaign ran for four weeks as part of the Association of Chief Police Officer’s summer drink drive campaign  but South Yorkshire Police operates an all year round drink drive policy.
