Average speed cameras on a seven-and-a-half mile stretch of the M1 have caught 3,000 drivers since they were switched on in May.The Leicester Mercury reports that penalty notices have been sent to drivers speeding through the roadworks stretch between junctions 23A and 25 in the East Midlands, where the carriageway is being upgraded to smart motorway.The newspaper quotes Jonathan Clarkson, spokesman for the Leicester, Leicestershire & Rutland Road Safety Partnership, as saying, "The average speed enforcement is in place to allow the 7.5 mile stretch of road to be upgraded to a smart motorway, construction is due to end in December 2018."Although 3,000 speeding vehicles initially sounds? very high, we are in fact talking about a period of around 17 weeks."This averages at around 25 vehicles caught per day and is a very small fraction of the 130,000 vehicles which use this road daily."
