Traffic Light Sensors...
Ok, so here's the response I got from the DOT about traffic light seneors not picking up bicycles, and whether NC is one of the states where you can consider the light a stopsign after three minutes....
"The loop detector has a current running through it that produces
a magnetic field around the loop wire. When a vehicle enters the
area the magnetic flux is changed resulting in a change of
inductance which the detector in the traffic signal cabinet picks
up as a call. Sometimes motor cycles have a problem depending
upon the sensitivity set on the detector. You will have to call
DMV about the red light. I have not heard that. I asked the State
Highway Patrol, and they said that you would get a ticket. I
beleive that I would get off the bike and become a pedestrian
pushing a bike on the side of the road."
I'll shoot an email to the DMV about the red light then.
