And so how should one respond differently to a blinker or a brake?
Either one means "this car is slowing down" so its pretty much a moot
point, especially since both rear lamps (and the CHMSL) are going to be
simultaneously visible 99% of the time.

OTOH, seeing amber in limited visibility conditions implies "approaching
vehicle" which is flat-out false in the case of amber rear turn signals.
Meaning you have to rely on simultaneously seeing headlamps or taillamps
to resolve THAT ambiguity. You're just trading one ambiguity for
another, and I'd argue that the "signal or brake" ambiguity isn't
particularly dangerous since you should assume that the car is slowing
to a near-stop (at least) under either condition. The fact of the matter
is that BOTH systems work perfectly well, both have done so for over 50
years, and I think you'd be hard-pressed to find a statistically
different number of collisions based on the color of the rear turn
signals, except for the "duelling reds" design you mentioned before.
(That's your open invitation to prove me wrong.)

 

International agreements, (yes the USA signed and ratified it) mandates that
amber just be used for flashing lights, front and rear and side. If the USA
followed that treaty requirement there would be no issue of having to guess
if a yellow light in the fog was the front or rear of a vehicle, it would
unambiguously tell you that a vehicle is either flashing a turn or if both
are flashing, that the vehicle is either very slow or parked. Instead, the
USA lets the car makers do whatever they want.

Has anyone done a study to show that our assumptions about amber being safer
is valid?

Front fogs are white, rear fogs are red (in an offset position) and amber is
for turning -- Europe.

There used to be yellow fog lights but very different to amber.

France used to have yellow headlights.

All standardised.

The only thing that isn't is whether headlights should be on during
daylight.

Red for STOP, amber for TURN, white for REVERSE....no, that's too complicated.

 

Well, the rest of the world has it all figured out, but yeah, it does seem
too complicated for America.
