  In a recent video, made to hep provisional license holders pass their test, the expert's clip has surpassed a whopping 644,000 views since posting as she puts the rule to bed.

She explained "I've been asked to explain signs like this one.

"This sign is saying that between Monday and Saturday, you can park between 8 o'clock in the morning and 6 o'clock at night, but only for one hour. "No return within one hour - that simply means that you're not allowed to drive out of your parking space, drive around the block, and go straight back into that parking space. "Well, not for an hour anyway," she added. In the post's caption, she clarified the rule, saying: "At other times you can park for as long as you want to." Now you know! This is not the only mystery to be recently solved.
