A WOMAN has been charged after police allegedly caught her driving while a man lay on her car bonnet dressed in a dinosaur onesie.

Broome police were travelling to Gantheaume Point, Cable Beach about 7.20am when they sighted a white Ford Falcon wagon travelling in the opposite direction.

Police allege the vehicle was travelling at approximately 60km/h with an adult male lying on the bonnet, facing the driver.

Officers stopped the vehicle and located the man still lying on the bonnet, smoking a cigarette, dressed in a dinosaur onesie and wearing a snorkel.

The 23-year-old female driver has been charged with excess 0.05% and reckless driving.

The vehicle was seized under hoon legislation.

The woman will be summonsed and appear in court at a later date.

The pair are French nationals, believed to be backpackers living in the vehicle.
