Many Belgian motorists try to make their number plates poorly legible in an attempt to thwart speeding checks carried out by the police. Some motorists remove paint from the numbers or letters in the hope that speed detection equipment will fail to recognise the vehicle. Others allow number plates to get very grubby.
Motorists whose number plates fail to pass the test are required to replace the item. A new front end plate can be purchased in the shops, but if it's a question of the rear plate, a new application for this official plate has to be made and the motorist is also given a new plate combination.
