More than 250 people are facing driving bans and large fines after getting behind the wheel after drinking alcohol or taking illegal drugs in Cheshire.
It follows a crackdown by the county's Roads Policing Unit throughout June, which saw officers carrying out additional checks.
All roads policing officers in the county are also equipped with both alcohol testing kits and drugs wipes, which instantly detect whether a driver is under the influence of alcohol or illegal drugs.
In total 121 people were arrested for drink driving, compared to 141 for the same period in 2016.
Another 131 were arrested on suspicion of driving under the influence of illegal drugs, up from 73 last year.
Superintendent Martin Cleworth, head of the Cheshire Police Task Force, said: “It’s disappointing to see that so many people still believe that it is acceptable to drive under the influence of alcohol or illegal drugs.
“The dangers of both drink and drug driving are well known - it affects your reaction time, making it harder for you to judge your speed, judge your distance between you and other vehicles and notice potential hazards. All of this means that you are more likely to be involved in a collision.
“All of those arrested as part of this operation will now have to face the consequences of their actions, which will have a significant impact on both their personal and professional lives.”
Police and Crime Commissioner for Cheshire David Keane said: “It’s pleasing to see the work that officers are undertaking to make Cheshire’s roads safer by proactively tackling people who believe it’s acceptable to drive under the influence of alcohol or illegal drugs.
“The consequences of drink and drug driving can be devastating; they can cause a ripple effect that can have shattering ramifications for not only the driver of the vehicle, but innocent members of the public."
