Question to the Home Office:
To ask the Secretary of State for the Home Department, if she will make an estimate of the number and proportion of passenger vehicles that do not comply with legal specifications for tinted windows.
The Home Office does not hold this information centrally.
The Road Vehicles (Construction and Use) Regulations 1986 governs the amount of light that must pass through the windows of a vehicle and therefore how clearly the windows can be seen through.
It is for the police to take enforcement action as they consider appropriate against those in breach of the Regulations.
