A LORRY driver's warning about the dangers of driving on the motorway without your headlights on has gone viral after being shared thousands of times online.

Ahead of more stormy weather this week, the Facebook post showing a lorry driver's view during heavy rain has been shared by more than 12,000 people.

The post, shared by NW Motorway Police on behalf of #KingsofTheRoad, says it is an 'urgent life or death plea'.

It adds: "Dear friends.

"Hitting the back of a 44-tonne truck in your little car will kill you.

"This is my view of you when you’re not using your headlights in bad weather.

"Remember, I may wish to pull out.

"I will indicate and if I can't see you, I will move out into your lane.

"If not cursing me and not slowing down, we will most likely make contact.

"I'm 44-tonne of steel and rubber, you're maybe one to two tonnes, I'll leave the result up to you.

"Don't be a fool- stay bright, stay alive."

Many other comments shared their own advice to help motorists remember including: "If your wipers are going, your lights should be glowing."

The Highway Code adds: "You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet).

"You may also use front or rear fog lights but you MUST switch them off when visibility improves."
