The consequences of illegally tinted windows: If you are driving with less than the legally required light transmitting through the windscreen and front side windows, the following could happen: You could be stopped and fined - you are effectively handing the police a 'reason' to stop your vehicle - the car could be impounded if it is considered dangerous to drive and/or could be given a prohibition order until removed! You will be required to remove the film (which will cost) and present your car to the police, confirming it has been returned to a legal status. If you have an accident and it can be proven that the reduced vision caused by the illegal film was a contributing factor, you are likely to get part or full blame - even if it was not under normal circumstances your fault! Even worse - your insurer - if they stand to be in a position where they are looking at full acceptance of liability (as you were at fault) - may determine that your insurance is invalidated! You will be looking at footing the costs on your own for your own vehicle and any other damage to third party vehicles or property.
