Speed cameras on the new managed motorway section of the M62 are working when the illuminated signs are off, it has been confirmed.
The section between junction 25 at Brighouse and junction 30 and Rothwell was completed last month and highways bosses have confirmed cameras remain active at all times.
Previously it had been thought motorists would only be automatically fined if they broke speed limits when the signs were on and the managed motorway variable speed limits were active.
A Highways Agency spokeswoman said: “The speed enforcement system is capable of enforcing variable speed limits including the national speed limit, including when the signs are blank.”
The managed motorway project was completed last month in a bid to ease congestion and smooth traffic flows during peak times.
