Yes, though (as with cyclists), only to deliberate law-breakers who go
through long after the light has changed. ISTR a policeman on TV years
ago explaining that red-light cameras were set not to fire for the first
few seconds of the red so as not to be too hard on people who made a
genuine miscalculation, but instead to target deliberate and determined
law-breaking.

You are supposed to regard an amber light as a stop signal, but as
usual drivers have consumed the safety margin as a performance
benefit, frequently accelerating through on amber, and then ask for
additional margin on top.

Just like speed cameras. If you make even a half-serious attempt
drive to the speed limit you are unlikely to trigger any camera, since
they are set to 10% + 3mph, and most speedos over-read anyway; instead
people drive to the ACPO prosecution guidelines and whine about being
caught for "a few mph over" when actually they are a few mph over the
guidelines, which are already 20% over the limit for a 30 zone.

When I was learning to drive I was told the meanings of the traffic
light colours could be considered as follows:

Red: Stop
Amber: Stop
Red-Amber: Stop
Green: Stop, unless it is safe to proceed.
