Traffic sensors not working

I have run into issues with the traffic light sensors not seeing my jeep. I sometimes will sit through a traffic light cycle and have it skip me until I do one of the following run the light or wait for another car to pull up behind me to trip the sensor.

Has anyone else run into this and what do you do?

Has anyone been given a ticket for running the traffic light?

Does anyone know what set the sensor off, weight or metal?

I don't have this issue in my Jeep, but I do on my motorcycle ALL the time.

That being said, most sensors are on top of the traffic lights themselves- nowhere really uses the 'weight' sensors anymore.

Is your jeep painted in camoflage? Maybe the little guy in the light didn't see you. Seriously most lights are on timers. During low traffic periods it is not unusual for a low traffic lane to be skipped in the rotation.

90% of the lights around here have the magnets in the ground. Only the newer light poles have cameras/sensors. I have trouble at one light near my house. It all depends on where you are at the line. If you are behind it then you have no trouble. If you are on the line or infront then it wont turn.

That is how it looks around my area you can see the cut outs in the road for the sensors.

I believe they sense metal with a magnetic field. Funny as most Jeeps are full of that metal stuff.

its a massive eddy current machine for those who refer to it as a "weighted" sensor. It has nothing to do with the weight of your vehicle. It has a current induced into it from the steel of your chassis which triggers the light timer. Motorcycles do not have enough heavy metal in them to throw the switch, and Semi truck trailers are mostly aluminum, which is why the light goes yellow so often when they are going through the intersection (the light already thinks it has passed)

I bet your jeep chassis is high enough off the ground, ( and not enough dense steel ) that the sensor doesn't trip easily.

I always wondered if I was the only one with that same problem. There are two lights in particular near my house that I always have trouble with in the Jeep(no issues in the truck at all.) The Jeep frame being too high sounds like a possibility.
