This is the shocking moment a drunk man on a scooter travels 14 kilometres the wrong way down a motorway as cars swerve to avoid crashing into it.

The incident took place on the M-30 motorway in the Spanish capital Madrid and was only brought to an end when the municipal police arrested the biker.

The suspect, who has not been named, was given a breathalyser test and was found to have over 1 mg of alcohol per litre of air exhaled, according to local media.

The Police Special Services Unit (USE) said in a statement that several motorists alerted them to the presence of a man on a scooter riding the wrong way on the M-30.

The arresting police officers said that the suspect showed “clear signs of being under the influence of alcoholic beverages”.

The suspect was arrested for reckless driving and endangering other people’s lives and for being under the influence of alcohol while operating a vehicle.

The police added that cameras set up on the motorway made it easier for them to intercept the suspect.

It is currently unclear if the suspect has been released from police custody.
