Drivers who fail to do one thing before setting off face breaking the law this week

Drivers have been told that they could be breaking the law if they fail to carry out one action asare set to plummet as low as -2C this week.

After a relatively mild start to November the has said we can expect wintry showers with sleet and snow especially in the second half of this week.

And motorists have been warned of Rule 229 of the Highway Code where it says drivers should ensure they have a clear view before setting off.

Experts have also recommended that motorists rub a potato across their car windscreens to prevent frost and condensation from forming during cold .

The trusty spud will create a protective layer of starch on the glass, which acts as a barrier against moisture build-up and ensures motorists adhere to the Highway Code. Drivers are cutting a potato in half and rubbing the exposed side directly onto the outside of your windscreen.

Motorists will need to apply the hack the evening before frost is expected, allowing sufficient time for the starch barrier to form, reported. A spokesperson for Motor Match said: "It might sound unusual, but rubbing the cut side of a potato onto your windscreen can make a big difference.

"The starch forms a protective film that stops moisture from sticking to the surface, so frost won't settle as easily overnight, and condensation will be less likely to form during rainy or humid weather. The starch creates a hydrophobic effect, meaning water droplets won't cling to the glass.

"This can improve visibility during heavy rainfall, as the water runs off the windscreen in a smooth sheet rather than scattering into distracting droplets."

Drivers are also being advised to increase the gap between you and the car in front to improve your visibility and ability to plan ahead, and be gentle on the pedals.

Sudden changes in wheel rotations can cause aquaplaning, where you lose control of the vehicle. Remember to make sure your car's condition is good, and check your tyre tread, and before setting off, make sure your windscreen is clear so you can see, say experts.
