Steven Edwards, who rents a commercial yard off Thurnham Lane, said some drivers use the road as a rat run, adding that recent icy conditions turned parts of it into a "skidpan".
He said: "Some people race up there but as a rule the locals do go quite slow.
"It's 30mph through the built-up area and then it goes into a national speed limit, which is ridiculous because you should never be doing that up there."
Bearsted is a small village with a population of around 8,000 and is well-known locally for grand houses and walking trails. It has few facilities but does boast a railway station with links to London. Maidstone, the county town in Kent, is two miles away.
