Over 250 drivers are facing a ban and large fines for driving after drinking alcohol or taking illegal drugs.
Throughout June Cheshire Police Roads Policing Unit carried out checks on roads across the county.
Macclesfield topped the table with 25 arrests for driving under the influence of alcohol and 46 for drugs.
In total 121 people were arrested for drink driving, while another 131 were arrested on suspicion of driving under the influence of illegal drugs. The figures compare to 141 arrests for drink driving and 73 arrests for drug driving in June 2016.
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.
“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.”
