Drivers astonished to learn what ‘H’ signs on lampposts mean

Many UK residents and visitors alike walk past these ‘H’ signs each and every day without giving them a second thought, Chronicle Live reports. However, as South Yorkshire Fire and Rescue Service explained, they actually play a very important role.

Taking to TikTok to explain, the services wrote: “POV: You’ve walked past these small yellow signs your whole life. But it was today you realised, finally, after all these years, they are there to tell firefighters where the hydrants are.”

The photograph displayed in the short video tells firefighters that there’s a 100mm water main 10 metres away – leaving people completely flabbergasted by the explanation. “I never knew. Every day is a school day thank you,” one TikTok user wrote, while another, added: “Well I learnt something new today thank you!”

A third added: “I’ve never even seen one of these signs never mind know what it means,” while a fourth commented: “Good to know. Thank you for sharing.”

“I used to think it was H for helicopter landing,” one user admitted – with others in agreement. “I thought it was a helicopter landing pad,” a second said, with a third echoing: “thought it was H for helicopters”.

Last week social media users were also gobsmacked to learn the origin of the term blockbuster. A TikTok star shared a video that detailed the word’s origin.

The word is so synonymous that the popular but now defunct video rental store named itself after the term – but many don’t know the word’s historic meaning. TikTok user Alice James, 30, shared where it came from – leaving people in shock as many admitted that they had no idea where it originated.

Taking to TikTok, where she uploads as @alicekjames, Alice said: “Are you ready to have your mind absolutely blown? I learnt what the term ‘blockbuster’ meant the other day and I haven’t stopped thinking about it. It comes from the fact that in the olden days if a movie was a blockbuster it meant the line went around the block to buy tickets.”

Alice’s video soon went viral and had over 150,000 views alongside countless comments.

One viewer admitted: “I didn’t know this either and I’m 59.”
