Ignored Heavy Goods vehicle signage

Church Street Byfield is deemed unsuitable for heavy goods vehicles according to the signage. For 2 years+ multiple large school coaches, large heavy double linked tankers (septic, oil), enormous horse trailers and crane lorrys come down church street hourly. They are getting stuck further down Church street and when coming back onto Fiveways cannot use the roundabout correctly due to their size and causing dangerous conditions. Sign to either be enlarged with weight details and enforced, or removed as pointless and unenforceable I raised this previsoulsy under 5567309 and after speaking with the police and parish council it is a west northants highways issue
