The Met Office has issued a severe weather warning for ice on North Devon roads overnight tonight.
Temperatures are expected to fall below freezing between 4.30pm today and 10.30am tomorrow.
A Met Office spokesman said: "Due to the recent wet weather there is an increased risk of icy patches, even on roads that have been treated with salt, where water run off/seepage may wash off any earlier salt treatment.
"The public should be aware of the risk of ice on roads and pavements."
Peter Rodger of the Institute of Advanced Motorists believes now is the time for motorists to adapt their driving techniques for winter.
Among his top winter driving tips, Mr Rodger provides the following advice:
- Check the weather before setting off and react to police warnings about closed roads.
- Travel with de-icer and a scraper and clean any ice or condensation from all the windows before journeys.
- A squirt of WD40 will prevent frozen door locks.
- Prevent wheel spin by setting off in second gear, releasing the clutch and accelerating gently and avoiding high revs.
- Drive in higher gears and not too fast to remain in control.
- Leave plenty of distance from the car in front as stopping distances are increased by up to 10 times in icy conditions.
- Lower speed early when on bends, approaching junctions or going downhill, reduce your speed early to retain control and be in a suitable gear before driving through them.
- If your car loses grip, take your foot off the accelerator and direct the front wheels where you want to go. If you find yourself in a skid, steer into it.
- Keep to the main roads as they are more likely to be gritted.
