High-profile stop-checks are being carried out by police in a campaign to clamp down on drink-drivers in the Bristol and Somerset area.
Police are concerned the World Cup will prompt more people to get in their cars after drinking with friends and have set up Operation Tonic as a deterrent.
The campaign includes visible random road blocks and will also target drivers suspected of taking drugs.
Seven people were killed and 35 injured in alcohol-related collisions in 2009.
Ch Insp Polly King, from Avon and Somerset Police, said: "With the football, I think people perceive drinking at home or drinking at a friend's house differently.
"They are more likely to get in their car afterwards. Our advice is, if you've had anything to drink at all - don't drive."
