ANOTHER ADVICE:
Finally, if you have a flag displayed on your car, minibus or van, it mustn’t obscure your vision. This applies to flags wounded in rear windows as well as those displayed outside the vehicle.
If you’re displaying a flag that contravenes any of the above rules, the general process will be for police to advise you on the correct procedure and let you off with a verbal warning, but this is entirely at the discretion of the officer, and if the way in which your flag is displayed is considered dangerous, then you could be charged with a vehicle ‘Construction and Use’ offence, the most likely penalty being a £100 fixed penalty and three points on your licence.
However, if you’re involved in a serious road traffic accident as a result of the offence, the penalty can be much more severe – up to £1,000 and imprisonment.
