You can't park there sir

You can park there. It's proven right in the picture.
Is it still parking if you're floating? That's more in the general direction of mooring.
Dammit, should have titled this "You can't moor there sir"
everything is a parking lot, if you're brave enough
I think that parking sign says it is further down the road, so they've parked prematurely. They'd have been better off focusing on the sign that says there is a river merging in from the left.
Not parking, just dipping his headlights.
