What I want to know is, what is the signal to the driver behind me, to please pull up to trigger the light? The one light that gives me trouble is on my afternoon commute, in heavy traffic, and will not trip for me. I can pull up far enough that the car behind *could* trigger the light. But, whatever signals I give, pointing to the ground, and then the light, I get only blank stares from the confused motorist behind me.

Many times, a right on red is just as easy, depending on your heading, and that's my usual answer. But, in that case, it would mean a long run the wrong way, or a u-turn in crazy traffic.
