A report from emergency services says collisions during England games at major tournaments rose during previous European Championships and World Cups. Officials fear the pattern could return as larger crowds, late finishes and busy roads combine.
The risk does not necessarily end when the pub closes. Fire and rescue officials say drivers may still be above the legal limit the following morning, particularly after a long night involving strong beer or wine.
The message is simple: supporters should not assume that sleep automatically makes them safe to drive.
A demonstration in Bowburn showed how complex these incidents can become. Crews used specialist equipment to cut the roof from a small car before removing a simulated casualty on a stretcher.
That process can take time, tie up several emergency services and leave families facing consequences far beyond a football result. Police also expect road-policing activity to increase around major fixtures, with busy nights and alcohol consumption creating additional pressure.
Public transport, taxis, designated drivers and alcohol-free drinks have all been highlighted as safer alternatives. The strongest advice is to separate drinking entirely from driving.
The excitement around England matches will be intense, but the consequences of one poor decision can last for years. Supporters can still enjoy the tournament without putting themselves, passengers or other road users at risk.
As the group-stage schedule approaches, the next test will come away from the pitch: whether fans plan their journeys early enough to ensure that the final whistle is followed by a safe journey home.
