Nottinghamshire Police have stopped and punished a BMW driver who was found to be driving with tinted windows that let in only 16 per cent of light. The force's roads policing unit said the required amount was 75 per cent through the front windscreen, meaning the motorist's windows were more than four times too dark.
They posted on Twitter: "BMW stopped with tinted windows which were so tinted that it was only allowing 16% light into the car. The front windscreen must let at least 75% of light through and the front side windows must let at least 70% of light through.
"BMW prohibited and driver reported #Prohibited."
