Its your legal right to pass and re pass an un surfaced highway such as this byway with vehicular rights. You pay road tax, it is your right to be able to drive it. It is also the councils responsibility to maintain the un surfaced highway. Although if is damaged by offroaders or greenlaners being idiots then they will close it until it is sutable to be driven again or until they TRO it for good. Drive it if you want to, don't spin your wheels if it gets boggy stop have a look to make sure its drivable if it not reverse to a safe place and turn around not in a farmers field. Compare the meercat, Simples! Jai
