Traffic Light doesn’t Change for a Motorcycle

Why don’t traffic lights change for motorcycles?

Have you ever sat at traffic lights waiting for them to turn red, but they don’t?
That’s because some sets of traffic lights are “vehicle actuated” which means there is some sort of sensor that detects the vehicle and trips the change sequence.

However, many motorcycles are not detected because they are either too small or not in the correct position on the road.

Sensors are often used at the intersections of busy and not-so-busy roads so that the main flow of traffic isn’t interrupted. Others only work at night and are on normal timed patterns during the day.
