Inspector Matt Boiles, from the force’s roads policing unit, said supporters should not rely on familiar supposed remedies.
“sleep, coffee and a shower do not remove alcohol from the body. Only time lowers the amount in a person's system,” Boiles said.
That warning is particularly relevant when matches finish late and fans face an early start the next day. A person may feel fine and still be legally unfit to drive.
Police say the checks will form part of the national Operation Limit campaign targeting drink- and drug-driving. Moody described the offence as preventable, while stressing the devastating consequences for victims and families.
Moody has urged supporters heading out to consider zero-per-cent beers or ciders if they need to drive. The safer option, however, is to decide how everyone will get home before the match begins.
Boiles said fans should “plan their journey home before going out, whether that means using a designated driver, public transport or a taxi.”
That preparation matters when emotions are high, public transport is busy and the temptation to make a last-minute decision can grow after a dramatic England result.
Officers are expected to carry out proactive checks during and after England’s group fixtures. The public has also been asked to report anyone suspected of driving under the influence, without putting themselves at risk.
As England’s next late kick-off approaches, the key message is simple: make the journey home part of the match plan. The tournament should be remembered for the football, not a preventable crash after the celebrations.
