Not enough information.
I've always assumed that these signs with the slashed P meant no Picnicking. Or maybe no Partying.
But does this mean that trucks over 3 tons can't party here? Picnic here?
Or maybe Peterbilt trucks that weigh over 3 tons aren't allowed here.
I wish they would print out what you're not supposed to do, it would be much easier...
and if you can't read, so you need the slashed P, then how can you read the "over 3 tons"?
What if you don't know the alphabet?
Beats me. Not enough info.
