Even with clear definitions, road safety experts emphasize that speed limits are not targets. Weather conditions, road quality, visibility, and traffic flow may require significantly slower speeds for safety. The RAC encourages motorists to use good judgment and prioritize safe driving over strict adherence to maximum limits. The ongoing confusion surrounding this sign has sparked a larger conversation about driver education in the UK. Many experts argue that learning shouldn’t end once someone passes their driving test. Refreshing knowledge, staying updated on highway rules, and practicing responsible decision-making are essential parts of being a safe and confident driver. By understanding signs like the national speed limit indicator — and treating them with the caution they require — motorists can help keep roads safer for everyone.
