[PRCo] Re: 42/38 on Smithfield Yellow-Green Light

[Herb Brannon]

It's a nationwide requirement for a CDL to have proper color recognition.
Hard to tell what the states are doing with a regular automobile license.
Sometimes, after observing how some people drive, I think they just hand
them out to any and all takers. The CDL has a US Government standard of
testing (written, actual driving, and medical) which, in order to legally
have the CDL, must be followed to get such license.
