Don't cross the road while the signal is red

I've never been there, but I think it's past that traffic light

The green light is the "go" signal

Drivers have to attend to the traffic signal

It is against the rule to cross the street while the red light is on

The taxi stopped dead at the traffic signal

Turn to the left without regard to the signal

This complex situation arose because signals from the environment itself can be inadequate

We experience and understand the world through signals that are received by the senses and interpreted by the brain - and both stages are subject to distortion

The driver couldn't have stopped at the signal

And it is only a very short step from there, to perception which occurs in the absence of all immediate signals and has to be labeled extrasensory
