If you had a freeway billboard, what would it say?

Billboard on a Freeway?
The premise wonโt translate.
Advertising hoardings
Are banned on motorways.
In the U.K. theyโre illegal
On busy motorways.
We just like our drivers
To focus on the road.
So Iโve a โFreeway Billboardโ
I guess itโs U.S.A?
My message to Americans,
โHave you picked the right road?โ
