sequential turn signals
VA DMV website only mentions 20/40 vision, and 110* field of vision—doesn’t say color identification

You say VA has this test, but do you know anyone denied a license because of it?

I don't know that many people who are color-blind....or, at least, have told me they are.
You may (?) be correct on the latest color-standards. I checked the latest VA DMV vision-standards, and it does not specifically mention color-vision standards any more. But that's the way they did it for decades....I've had a Virginia Driver's license for some 50 years. You looked into a lighted scope, with color-dot-patterns, and told them what number-pattern you saw on the dots.
That's interesting, because, at night, one should be able to tell the flashing red and blue (or, in some places, all-blue) flashing lights if you a being stopped by police, particularly with all of the publicity given lately as to how police stop people, why, and how they are treated when they are stopped. Also with the publicity given to the fact that criminals sometimes try and impersonate or imitate police-cars with red and blue lights.
Do you know anybody who is colorblind? They compensate. They can see blinking lights and see where the light is on the traffic lamp. They also see shades. They see flashing lights on a police car and know they need to pull over. Most people who are colorblind have been colorblind their whole lives, and don't know any different.
wow, mmarshall, can't believe you're so down on people who are colorblind. colorblindness is apparently a mostly male affliction but affects 5-10% of the entire population, so if you think they shouldn't get licenses, well, i'll just say i'm glad you're not in charge. 

Fourth, I've got enough awards and Letters of Commendation sitting around my house from my working days, when I WAS in charge of some things. Fifth, I'm out of this thread.....I've had enough of it. Sixth....well, I won't go into that now....you'll see for yourself.Last edited by mmarshall; Aug 30, 2020 at 09:48 PM.

No, it's not necessarily a matter of colorblindness. Criminals who impersonate police officers (and they are out there.....their presence is not a theory, but a fact) are only interested in you pulling over. Once the wolf has the sheep in its grip, little else matters.

First, I'm not down on them..........I just wasn't sure about the latest laws were.
Believe it or not, some states will give you a Drivers' License if you are colorblind.

plus you seem to be unaware that most colorblindness is red/green differentiation, not red/blue.

And I do think we've all let this discussion get a little too heated....with some misunderstandings.
All this to say, while colour is a factor, it is not a determining factor. Turn signals (when in proper working condition) have a pretty specific on/off cadence, regardless of whether they are the standard on/off, sequential, or fade-to-off. The difference between the three is incredibly minor (IMO) - you can still tell that any of those lights are turn signals (regardless of colour) because you can recognize the cadence. If I were colourblind, I would use this same metric (the cadence) to discern emergency response vehicles from maintenance vehicles or tow trucks, for example.
