I was told by the traffic officer and the vosa guy that stopped me in my Lexus, that anything other than a factory tint is illegal. I had my fronts done to match the factory rears of my IS200 sport (that were done as standard) and got a £30 fine and told to rip them out. What annoyed me about this though, was the fact they waiting outside my place of work at the time for me to finish. They even said they were waiting for me for an hour since 5 as thats when i usually left, but i finished at 6 that day!!!!!

I was told its more to do with the fact they cant see whose in vehicle rather than it being to do with saftey. The light tints i had did not affect vision at all in my opinion.
