The RAC had its busiest day in 10 years on Tuesday with 9,500 call-outs, but believes this figure could be topped on Wednesday as conditions worsen.
The breakdown rescue firm’s road safety spokesman, Pete Williams, said: “For drivers, the first consideration is whether your journey is really essential or whether you are able to avoid travelling during the worst conditions.
“If you must drive, do your preparations – check local weather and traffic reports, plan your route carefully using main roads where possible and consider alternative routes in case you encounter difficulties.”
