The main road through the village (see map) is restricted (All Motor Vehicles Prohibited - Except For Access) by the terms of a Traffic Regulation Order (TRO). To view the original Order, click on this link: TRO - 11th June 1993 (£30 Fixed Penalty Notice applies).
Banbury Lane through Blacklock's Hill (linking the A422 to the B4525) is subject to restrictions on parking of lorries exceeding 5.0 tonnes at all times. See map.
In both cases the restrictions are clearly signed.
