IF YOU have driven on the M4 over the past couple of years you are likely to have comes across one of the temporary speed limits in place on the motorway.

Upgrading junctions 3-12 of the M4 to make it a smart motorway has meant temporary speed limits of 50mph and 60mph have been enforced on the road as works progress.

Automatic Number Plate Recognition (ANPR) cameras have been used to monitor the average speed of traffic over sections of the road.

The temporary speed limits are legally enforceable, meaning drivers who exceed this top speed are liable to penalties.

And people do get fined, as court filings show.
