Ever spot a 5 mph speed limit sign and wonder if itβs legally enforceable, or just a polite suggestion? π€
Here is the quick breakdown:
On Public Roads: Official Highway Code speed limits generally start at 20 mph. A 5 mph circular sign on a public highway is extremely rare and usually indicates a private property boundary or restricted facility ahead.
On Private Land: Youβll frequently see these posted around car parks, industrial estates, depots, and site entrances. While local authorities and police donβt enforce them under standard road traffic law, landowners can take civil action if speed rules are ignored.
Safety First: Regardless of legal technicalities, these limits are put in place for pedestrian safety and heavy machinery areas. Keeping your speed down prevents unnecessary accidents!
