Britons have been issued with an urgent warning from experts about leaving their cars unattended this winter, as they could be more at risk of "frost-jacking".
Temperatures have plummeted in recent days, with many drivers being forced to clear frost and even snow from their car windscreens as winter sets in.
While some will enjoy the cooler temperatures and the shorter days, experts are warning that motorists could be leaving their cars at risk of being stolen.
So-called "frost jacking" occurs when a criminal steals a car that has been left unattended with the engine on, while the owner waits for the vehicle to defrost.
To avoid having to sit in a cold car before setting off, drivers will often leave their vehicles running while the fans clear any condensation.
Research shows that British drivers are significantly underprepared for the winter weather and colder temperatures.
Only a quarter of motorists have taken steps to mitigate the colder temperatures by putting an ice scraper in their cars.
Just one in five have switched to a windscreen that doesn't freeze when thermometers drop below zero.

Tom Banks, car insurance expert at Go.Compare, which commissioned the research, issued a strong warning to motorists heading into the winter months.
He called on drivers to ensure they are thinking more prominently about winter car maintenance, with simple measures, like bringing an ice scraper, making a huge difference.
The expert continued, saying: "It's important to thoroughly de-ice your car before driving to make sure you have adequate visibility, and this process can take a while.
"But while it's tempting to just turn your car on, blast the fans, and go about your business, leaving your car unattended for any length of time is a huge security risk.

He noted that leaving running cars unattended was also a legal offence, adding to driver woes if their vehicle is targeted.
Drivers who try and clear frost and condensation from their vehicles with the engine running could be accused of idling, especially if they are near a school.
Local authorities have the power to issue a fine of £20 for engine idling if a driver refuses to switch off the engine when asked. Fines can be as expensive as £80 depending on the location.
Many roads outside schools across the UK are 'idle-free zones' | GETTYMr Banks called on drivers to avoid risking hefty punishments by preparing themselves for the cold weather.
"Instead, we recommend taking a more hands-on approach: use a good quality ice scraper, and apply de-icer to speed the process up," he said.
With the rise of electric vehicles, more drivers could avoid the risk of leaving their vehicles unattended with the engine running.
Many modern vehicles, particularly electric cars, have remote features that allow the driver to pre-heat their vehicle before setting off on their morning commute.
