A BARMY motorist has been banned by police after converting a beer crate into a mini quad bike.

The micro machine was given its last orders after Wolfi Maier, 24, tried to outrun cops on the booze machine in Dautphetal, Germany.

The biker said he had only just finished the vehicle and claimed it was on the way to a test drive at a private racing track.

“It looked good but it was not licensed to travel on the road – so we confiscated it,” one officer said.

“The vehicle featured a tuned-up engine that normally only goes about 15mph but this was much quicker.”

He added: “It would certainly make drink driving more risky.”

Police told the Austrian Times the vehicle could yet be returned if the owner promised not to use it on the public roads again.
