I had to go testify in traffic court one day on a citation I had written a kid on running a STOP sign; when he got in front of the Judge, the Judge asked him if he knew what STOP meant? The kid tried to be smart and responded "squeal tires on pavement" and snickered when he said it; the Judge didn't find it the least bit funny and suspended his license, fined him and made him go to traffic school. I worked too many serious injury accidents and fatalities from people running stop signs in my career.
