@roger,
I was curious so I called a police officer. That person was busy on a fatal and said no, not all traffic violations are criminal.
That person said it was changed back in the 70's. That person said speeding (not neg or reckless) is an infraction. They also said running a red light or stop sign can be an infraction. That person said equipment problems on a vehicle is an infraction. Also illegal lane changing is an infraction.
I don't keep up with traffic violations. Luckily I can call a police officer and ask questions.
