Our road needs to be reassessed to reduce the speed of hgvs/all vehicles on a back road

For many years us residents have complained about the speed of traffic on a back road with 2 sharp bends and numerous concealed entrances, we have had our family pets sadly killed, family members injured by vehicles and our own vehicles damaged trying to get out of our own entrances, something needs to be done now before it's too late! Our children are fearing for their lives because the speed of them. The council seem to think it's ok for this to be a 60mph which is 100%not suitable.
