Amber means ..?

[Martin Cassini]

The following comment appeared on my YouTube channel (mjcassini): "I was travelling with a friend and his young daughter. She asked what the red light meant. He said, Stop. And green? He said, Go. And yellow? GO FASTER! I laugh at the joke, but also the fact that it is what a lot of people do. Later, of course, he explained what it really meant."
