Great point Cece! Many years ago I was driving down a highway that had a cross street that had a stop sign, very clear large sign below said, cross traffic does not stop, well a non american woman that could not speak or read english ran this stop sign with her 5 children beside her in her pickup as I T boned her almost killing each and every one of them. I wrote letters to the state, I was pissed that the state of Texas gave her a drivers license when she could not read the sign!!
