ALMOST 200 illegal vehicles have been detected by M50 toll cameras since the start of the year.
Gardai have been alerted to dozens of dodgy vehicles every month as a result of barrier-free tolling. Motorists are being caught out as they drive past the toll cameras.
The system has detected cars that have cloned number plates, have been stolen or that shouldn't be on the road at all.
In July alone, there were 33 such detections, including some for cars that were previously 'written off' or 'scrapped'.
