Speeding M4 drivers around Port Talbot will today begin receiving warning notices about possible prosecution.
Hundreds of motorists a day are ignoring new average 50mph speed enforcement cameras on the M4 through Port Talbot and one was recorded at 98mph.
The four cameras were installed in October on a two-mile stretch and are currently being tested and monitored.
Enforcement action comes into force on 19 January, with currently up to 700 drivers a day ignoring the speed limit.
