Cheshire Constabulary will target drivers who get behind the wheel while under the influence of drink or drugs as part of a month-long summer campaign.
This campaign is coming to an end but...
Officers will be reminding road users about the dangers they face while drink and drug driving and urging the public to report those they believe are under the influence.
The operation will see officers from the force's Roads Policing Unit carrying out additional checks on roads across the county in a bid to reduce the number of offenders and casualties.
During the previous operation in June last year, officers arrested more than 160 drink drivers as well as more than 90 drug drivers.
Superintendent Martin Cleworth, who heads up the force's Taskforce operations, said: "Driving under the influence of alcohol or drugs is extremely dangerous and I cannot reiterate enough how much drivers are risking their own lives and the lives of others.
"There are also serious consequences for anyone who is caught, not only do they face losing their license but they also face a large fine, going to court and even the possibility of being sent to prison. All of these things can have a significant impact on someone's life, including the risk of losing your job.
"Throughout June, officers will continue to educate and inform drivers of the dangers and risks they could face if they step behind the wheel while unfit through drink or drugs.
"I also want to urge people to help us by coming forward to report anyone they believe may be under the influence. Together we can help make the roads across the county safer for all to use."
Police and Crime Commissioner for Cheshire, David Keane said: "One of my policing priorities is to help make the roads across Cheshire safer for everyone. Driving whilst under the influence of alcohol or drugs can have huge ramifications not only on the driver but also other road users and the local community.
"Operations such as this help to further highlight and raise awareness of the dangers caused by drink or drug driving."
