Try making sense of this sign. The obvious interpretation would be that you shouldn't speed down a hill if you are in a wheelchair, as an alligator will swallow you up at the bottom of the hill. Usually, signs are located before the designated area and warn road users of
what lies ahead.
If you look at the road in front of the sign, you'll notice that it doesn't have a downhill nor does it have a dam that crocodiles have congested. Let the sign serve as a good laugh and get on with your life if using this road.
