Warning: This video shows the moment of the head-on collision

Police have released dashcam footage of a crash involving a drunk motorcyclist, to encourage other bikers to be safer on the roads.

The head-on crash happened in Stevenage in March.

The rider, who was critically injured, was found to be nearly twice the drink drive limit.

No-one in the car he hit was hurt but police say are releasing the footage in the hope it brings home the serious consequences of being over the limit.

At court in July, the motorcyclist was disqualified from driving for 18 months.
