With the Euros set to start tomorrow, you might be getting all patriotic and considering attaching window flags to your car.
But beware - your seemingly harmless support could actually land you a £1,000 fine.
As per the 'Ask The Police' website, which was created by the PNLD (Police National Legal Database), a national organisation governed by West Yorkshire Police, you might want to consider a few things before you throw up that St George's flag.
The first is 'vision'. Does the flag mean that you or any other drivers can't fully see the road? If so, you might be causing some trouble for yourself.
Another thing to take into account is how secure it is. It could be classed as an insecure load if it could fly off and cause damage or injury.
And despite what they say, size does matter. A normal flag - which the PLND describes as about the size of an A4 piece of paper - wouldn't be expected to cause any issues, but of course, larger flags could.
The final thing you're advised to take into account is the possibility of having an emblem or mascot on the car that could strike someone and cause injury. If it's not likely to, because it can bend or retract, you should be safe on that count.
The website adds: "So, although there is not a specific offence, you could commit an offence by having a flag on your car.
"It is the officer's discretion whether or not to take matters further if he/she feels that an offence has been committed."
If you break any of these rules, you could be slapped with a £1,000 fine for 'failure to have proper control of vehicle or full view of the road and traffic ahead', as per the Highway Code.
That would surely not be the best way to celebrate the Euros.
The tournament was rescheduled from last year, on account of you-know-what, hence being called Euro 2020 rather than Euro 2021.
Let's hope that Gareth Southgate's lads are all fighting fit, with several key members of the squad currently struggling with injury.
Right back Trent Alexander-Arnold had to pull out of the squad last week following an injury to his thigh in the team's match against Austria.
There are also concerns over Jordan Henderson and Harry Maguire.
Goalkeeper Jordan Pickford revealed that he has been seeing a psychologist this season to help give him the edge he needs to perform at his best.
He told The Telegraph: "I just feel in a very good place.
"I began working with a psychologist at the start of the season. You know in football, those little one or two per cent gains - just to raise your ability on the pitch and what you can achieve - are crucial."
