Police have released footage of the moment an officer was nearly hit by a skidding car on the M57, as part of their effort to persuade motorists to slow down in bad weather.

The Mercedes slid across the motorway and on to the hard shoulder, before hitting another vehicle.

The constable had been at the scene of a multiple vehicle crash just before Junction 2 in Knowsley, when the car slammed into a Highways Agency van on 30 January.
