I am by no means an expert, but from what I understand the loop sensors that are installed at signal lights work by detecting a change in the magnetic field around them. This means that vehicles get stuck at lights for 2 reasons:
1. They or their engines are too small to be detected (usually motorcycles)
2. The magnetic field was reset after the vehicle was stopped on them. i.e. The vehicle stopped just when the light turned yellow. This can happen with any sized vehicle.
The solutions posted so far work because the all seem to change the magnetic field in one way or another thereby tripping the sensor.
Another possible solution (for both vehicles and motorcycles) is to slip your vehicle into neutral and rev your engine a little bit. By increasing the revs, you change the magnetic field and the sensors should "see" you. It seems to work around where I live. I'd be curious to see if it works for anyone else. Good luck!
