Which rule sounds stupid, but actually makes a lot of sense?

1. During community service, we would have to go up to this small mountain town in a convoy behind our professor. He would have one of us drive and the passenger would have a walkie talkie. He would do check ins every half hour, you couldn't pass him in the convoy, and he would announce every single time a car was coming from the other direction while on the mountain. It seemed really stupid at first, but when we were heading back down, we realized just how small the road was and how fast some of these other drivers were going. He was literally putting his car and pretty much his life in front of us to make sure if anyone would get hit head on or roll off the side of the mountain it would be him and not us.

2. Crossing your arms and feet on a water slide. I decided last summer to hold my nose while going down the slide, and figured I’m a grown ass man I’ll hold my nose if I want to. I bet I looked real cool punching myself in the eye.

3. [This story](https://www.reddit.com/r/talesfromtechsupport/comments/8l0w7j/this_includes_spit/) fits well >I was at a medium sized plant in Wisconsin about to do some support on a holding furnace. Before I am allowed to do work I have to review their safety material and sign a few sheets. Kinda standard stuff at plants approaching this size. >As I am flipping through the book I get to the safety section regarding their melters and something peaks my interest. Normally, they’re pretty repetitive, but this page had one rule that I’ve never seen anywhere else: “No water on the operating deck. All water must be in the operators room. This includes spit.” >What? Spit. Why did it have to specify spit? So I ask the maintenance supervisor. >“Oh well this is something you’ve gotta hear. We had an operator who liked to chew tobacco. Not really an issue as he kept his spit bottle in the operator room. Disgusting, but whatever. He showed up and did his job. Until one day, he decided to put the spit bottle in the pocket of his shirt as he did his job. At first it wasn’t an issue, until toward the end of the shift when it got more and more full." >"You see he opened the furnace to check temperature visually. As he bent over it spilled out into the furnace. BOOM. Metal flew everywhere. He died in seconds. His body was 90% covered in iron. The kicker was his family sued afterwards. They argued that the no water rule was vague and he didn’t know it applied to spit.”

4. “No dogs on trails” If you’re at a park or trail with a no dogs sign, please obey it. It’s because dogs are scent animals, no matter what they do they leave a scent for days. Sensitive wildlife will not come around if they smell a (predator) dog. Some will even abandon the area permanently. If you see “no dog” signs there is likely sensitive/endangered wildlife in the area. They must use that area as a home. So please respect the signs. They’re there for a reason.

5. No recording devices/cellphones even in your pocket on rollercoaster. I used to work at Busch gardens and guests would get SO PISSED that we would ask them about phones in pockets and kick them off the ride if they didn’t put their phone in the cubbies. But it’s because when a phone/camera that you’re holding to record your epic ride gets dropped or falls out of your pocket it has a high possibility of hitting someone, and guests have gotten seriously injured from it, and could even die. PLUS as an employee it’s a huge safety violation and if I let you take it once I see it, I could get fired Edit: I also doubt anyone is wondering this but prosthetic limbs fall into this category as well. And yes, I have had to hold onto a few prosthetic legs and one arm while I was an employee there.

6. Years ago, I was in the IT department and the company had a rule that “all the members of the IT department were not allowed to ride together in one vehicle to external events.” It meant the four of us had to take two vehicles to go out for lunch, but it made it less likely the whole department would die in a car crash. I have seen other companies with rules stating all the executives couldn’t be on the same flight.

7. The mattress tag that which everyone thinks says "do not remove under penalty of law". It actually says "do not remove before consumer under penalty of law" or words to that effect. At one time recycle mattresses were a thing. Companies would take old mattresses, remove the ticking and upper most layer of batting, recover it and sell it. Unscrupulous companies would sell them as new and the practice helped the spread of bedbugs. At first, new mattresses were to have a white tag and recycled mattresses had a yellow tag. Eventually recycled mattresses were banned and most thrift/charity stores won't take them, leaving only private sales as the only way to obtain a used (but not recycled) mattress.

8. It’s illegal to put an ice cream cone in your back pocket in Kentucky. Because people used to lure horses away with the ice cream so they could pretend to be innocent if caught.

9. The Monopoly Rules. If you play by the actual rules (no money in free parking for example) the game goes WAY FASTER because you're not bombarding the game with a random unnecessary influx of $$$ all the time.

10. I used to work in a fairly dangerous factory built in the 1950's. It's still operational today. I was around a lot of insanely long belts and rollers, moving maybe 120rpm (belt was at least 180yrds long) but the only bit of advice I got on my first day was "Don't put your finger where you wouldn't put your dick" My first thought was "Is that it? Surely I will have some sort of safety training or at least shown where was dangerous and what not to do but, nope. Still have all my finger/toes/limbs etc tho
