Before taking your driving test in the U.K., you must pass a theory test, covering road laws, signs, and a hazard perception section. Yet, despite its importance, many drivers seem to have forgotten the meaning of one common sign. This particular sign is round, white, and features a thick black diagonal stripe. Found across roads in the U.K., it indicates the national speed limit, but online, motorists have shown remarkable confusion.
On Reddit, one person claimed, “I’m convinced 99% of drivers don’t know what this sign means.” Comments ranged from joking guesses like “National drifting zone” and “go as fast as you want” to incorrect interpretations of minimum or maximum speeds.
