Drivers with certain medical conditions are being warned of fines they could face this winter as plummeting temperatures put millions at risk.
The Met Office has issued warnings to drivers across the country amid fears that weather conditions will worsen over the coming months.
While it stated that average conditions were most likely for the winter, there will be cold dips and even the potential for fog and snow over high ground in England, Scotland and North Wales.
Experts have cautioned that drivers who have not declared a common health issue could find themselves on the receiving end of a huge fine, and even risk being prosecuted.
With freezing temperatures expected in December, arthritis can flare up for many Britons, causing them a great deal of pain.
Arthritis UK states that drivers must inform the DVLA and their insurance provider if their condition impacts their ability behind the wheel.
The same applies if they use special controls for driving, although not all motorists need to declare their arthritis to the DVLA.
Graham Conway, managing director at Select Car Leasing, said drivers can be fined up to £1,000 if they fail to tell the DVLA about a medical condition that impacts their ability behind the wheel.
Drivers are expected to tell the DVLA of any notifiable medical conditions that may impact their ability | PA/DVLAHe said: "It's a sad fact that frigid winter temperatures can exacerbate the symptoms of arthritis, with colder weather ushering-in joint stiffness and reduced mobility.
"That can have an impact on someone's ability to drive. A prescription for arthritis medication won't necessarily warrant you having to tell the DVLA about it."
The DVLA advises that drivers should talk to their doctor when deciding if they need to tell the DVLA if they think arthritis is having a significant impact on their ability.
Drivers can face huge consequences if they are involved in an accident as a result of their condition and they haven't declared their ailment.
