Police have launched their annual Christmas drink drive campaign.
The operation, which will run until January 1, will see extra patrols on the roads of the city and county.
Officers stressed that they will be stopping drivers they suspect of being over the legal alcohol limit at random locations at all times of day and night.
They have warned drivers to be aware that they can still be unfit to drive the morning after their last drink.
The force, which catches an average of between 80 and 90 over the limit motorists each month, launched the campaign at St George's Retail Park, near Leicester city centre, today.
Graham Compton, the force's road safety officer, said: "Hopefully, with all the work we are doing to warn motorists of the danger of drinking and driving, we'll be able to reduce that average figure during this campaign.
"Drinking and driving is a serious criminal offence and people must realise there are serious consequences.
"If they cause an accident they could kill or seriously injures others or themselves.
"People also have to realise they can still be over the legal limit after a night's sleep."
Chief Inspector Steve Potter, of Leicestershire Police, said: "Cracking down on those who drink and then drive is a year round commitment for Leicestershire Police.
"However, we are very aware the festive season can present opportunities where people are tempted to drive after drinking.
"We would advise drivers to plan ahead by leaving the car at home, sharing a taxi or taking public transport or alternatively nominating a designated driver who will avoid drink alcohol."
The campaign was officially launched at St George's Retail Park, near the city centre, during one of the force's regular Fatal Four operations.
Between 8am and 12pm officers stopped 40 motorists who were either speeding, not wearing a seat belt or were using a mobile phone.
All 40 were tested for excess alcohol but none were over the limit.
Driving without a seatbelt, speeding, using a mobile phone at the wheel and drinking and driving are the four most common causes of crashes.
Also, three people were handed over to immigration officials who are assessing their right to be in the UK.
