The Highways Agency is carrying out five days of extended testing of the new managed motorway system on the M62 between junctions 26 at Chain Bar and 27 at Gildersome.

The systems will be tested from tomorrow until Sunday.

During busy periods, operators in the regional control centre in Wakefield will set overhead message signs to tell drivers they can use the hard shoulder as an extra lane.

When the hard shoulder is not open to traffic, shown by a red X or a blank signal over the hard shoulder, it is illegal to use it, except in an emergency.
