Ultra low speed limit signs always make me laugh.

My car has an analog speedometer and the first number is 20. The best speed they’re going to get from me, especially driving up a ramp in stop-and-go traffic is “less than 20”.

I used to live in an apartment building where they just posted a speed limit sign that said “DEAD SLOW”. My friend got a complaint letter from strata that he was speeding. He replied that “dead slow is a nautical term meaning a ship must travel in such a way that they don’t lose the ability to steer. I was not operating a boat and my ability to steer was never in question.” They gave him a “warning” and said the actual speed limit is 10; though that wasn’t on any sign nor ever written anywhere.

I do the 20km/h, no matter how much it pisses other people off.

But that 5km/h MUST be there as a liability waiver for the ferry; no car’s going to go less than 8km/h up one of those ramps. But if anyone tries to sue them they can just argue that the person was speeding so they’re not liable.

Check the Staten Island Ferry.

TSA has posted signs telling people to drive at 4 1/2 miles an hour.

Because 5 mph would be insane.

And just in case you were thinking that it was an exact measurement translated from metric.

4.5 mph = 7.24048 kph.
