Thames Valley Police has shared advice with motorists on preventing vehicle theft after new figures revealed a 13 per cent drop in vehicle crime across the region.

The force has outlined several measures to keep vehicles safe from thieves after the data showed a 13.5 per cent drop in thefts of vehicles, thefts from vehicles, and vehicle interference.

The fall comes after tackling vehicle crime became a national focus, with the National Police Chief’s Council leading a nationwide Vehicle Crime Intensification Week.

Thames Valley Police emphasised the importance of locking vehicles, even when parked on a driveway or at a petrol station, and ensuring all windows and sunroofs are closed.

It is illegal to leave a vehicle running unattended to de-ice or warm up in cold weather, and insurers will not cover theft in such cases.

Motorists are also advised to keep their keys safe and out of view at home, as thieves have been known to use sticks and hooks through letterboxes to steal them.

For those with keyless entry cars, it is recommended to keep keys well away from the car when at home and to use a signal-blocking pouch, such as a Faraday Bag, to prevent relay theft.

The police also advise motorists to be aware of carjackers and to drive with doors locked in traffic.

If bumped from behind, drivers should pull over somewhere safe and preferably where there are people, and in the event of a threat, it is advised to hand over the keys and call the police.

Parking in well-lit and busier streets is recommended, as well as using car parks with a Park Mark safer parking award.

Motorists are also advised to watch for illegal tow trucks and to report any suspicious activity immediately.

Fitting additional in-car security locks, such as steering wheel locks, pedal boxes, and gear stick locks, can also prevent theft.

Police warn electronic devices can be used to jam the signal from key fobs, so motorists should always manually check their vehicle has locked before walking away.

When buying a vehicle, it is advised to check the DVLA V5 document and to ensure the vehicle identification numbers match those on the document.

The police also recommend securing engine management diagnostic ports, which can unlock and start a vehicle.

Speaking after the data was released, Thames Valley's police and crime commissioner, Matthew Barber, said: "It is very welcome that vehicle crime has fallen 13.5 per cent across the Thames Valley over the past 12 months, but it is important we maintain this trajectory."
