Traffic lights always have the green light at the bottom to be inclusive to speeding people (and colorblinds)

I'm red green colorblind and never had an issue with the traffic lights colors.

I have had days where the sun was so bright i could barely make out what light was on.

In Canada yellow means stop, unless it's too late to stop then you need to get through the intersection during the grace period before it turns red.

Does it mean something else in the USA?

no, that is pretty much what it means in the USA. it is a heads up the light will be red in a moment

That’s the legal purpose of a yellow light, yes. However people have been getting worse and worse with actually following it. Now on green I always wait a few seconds for some yahoo to come flying through on the side street claiming he made it on yellow

No red light cameras in your parts? I get this happens, but if it's this frequent makes me wonder if there's ever any fines for it? Depending how late it is should be instant licence revokation and fine in my opinion.

A couple decades ago, there was a scandal in, I think, Chicago. They used red light cameras but then kept cutting the timing of the yellow lights, turning it into a revenue generating exercise. People remember.

That sucks (both the people running lights, and the failure in red light cameras) stay safe out there friend.

What do you mean? If you entered intersection, you can compl... Right, America. Nevermind.

I watched you very carefully. Red light stop, green light go, yellow light go very fast.

I did not expect a sick Starman reference today.

I have a soft spot for Karen Allen but it's not in the top five John Carpenter films.

Yeah, but it literally doesn't mean that. It just means "warning."

Edit: in most US jurisdictions, it means warning. TIL about Canada and UK rules. Good thing I never got pulled over there for that. Thankfully the UK has more roundabouts, too.

11

It means "if you are able to stop safely, you MUST STOP. Otherwise, you must go through the light quickly".

Same in Russia, Ukraine and Belarus*

*Belarus seems to have multiple exceptions

2

Not going to say about entire Europe, but in RUB countries yellow means stop* like red does.

*unless you are driving bus or few other edge cases

I bet traffic lights are extremely triggering for Picard. The whole "there are four lights" thing. Plus one of the lights is green which probably reminds him of every borg device ever.

i remember visiting extended family back in, i think, the early 80s. down in alabama or something. their traffic lights went green>yellow>red, as expected. but then went red>yellow>green.

More or less. If you're paying attention to what's going on around you you'll notice other traffic stop before your light turns green. There's also typically a second or two where all lights are red before one turns green to make sure the intersection is clear.

Why would you need a warning? It's not a race. In fact, that's probably part of the reasoning of not having a yellow before changing to green

That's what traffic lights do here in Spain. I don't actually know if Red-yellow-green has any advantage

This is normal in Europe too, and actually helps to clear up the traffic. You see red+yellow lights on, you put on first gear and prepare to start moving.

in many (maybe even 'most') american towns and cities, there would be too many drivers going on that yellow and not waiting for the green.

7

There's a clear difference though. Yellow = no-go, yellow+red = prepare to go

In the UK, they go Green-Yellow-Red-Yellow-Green, which seems pretty sensible to me.

4

Imagine green-blinking green-yellow-red-red+yellow-green.

2

Czechs do this too. Gives you time to menacingly rev your engine at the car next to you.

2

In some biggest country traffic lights FSM looks like this: red->red+yellow->green->blinking green->yellow->red, and can transition to blinking yellow from any state.

This joke needs to be delivered by Commander Kruge (from The Search for Spock), not Captain Picard.

I read this to my wife.

Her response was "Stop."

"No honey, that would be the red light."

Yeah.. the red light/green light game really messed up people’s understanding of what the yellow light is for.

Yellow means stop, red means stop really hard

2

When I was a kid in the 80s, the language my state used was that the yellow light means "prepare to stop."

Not sure if still true. Much has changed since then.
