HGV

Motorists are also being warned to follow the official diversions put in place, after a HGV driver had to be rescued by Surrey Police from Pyrford Lock after following Google Maps instead.

Charlene Morrisey, from Airdrie, was on her way to a camping trip in a remote area near Mount Agung in July when her scooter collided with an HGV.

"Luckily I've done a HGV training course, but I didn't know if I could find a new career as a lot is online now," he said.

But he said there had been "too many lorries on the road" and urged HGV drivers to heed police warnings not to travel.

PC Prior, Mr Welford and a teenage boy who had been a passenger in Mr Welford's car were all struck by an HGV at around 08:55 GMT while stood on the roadside.
