FYI, they're usually not weight sensors, but instead they are triggered by a current momentarily induced by a large hunk of steel moving over top of them. If you find yourself in this situation in the future, you can try reversing and pulling up in a slightly different lane position. (preferably by braking harder, so as to increase your velocity over the sensor and the magnitude of the current induced.) Look for hexagonal cutouts in the asphalt and attempt to drive directly over them.

Thank you for this. Yes there are visible round cutouts in the concrete. So basically roll back and forth over them until the light changes?

Yep, the faster the better. (safely as you can, of course)
