Quad bikes and all-terrain vehicles are among the items most likely to be stolen in rural areas, and in the light of recent thefts, police are urging owners to:
• park as close to your premises as possible, ideally in a locked garage or well-lit open space preferably out of sight from nearby roads
• remove keys when not in use, and do not leave them near the vehicle
• secure with wheel clamps or by chaining to a ground anchor / locking post
• mark or customise your vehicle so it is easily identifiable
• consider fitting tracking devices for high value vehicles
• keep a record of all vehicles, including serial numbers and security marks.
