Random Thought: Red-light Cameras vs. Emergency Vehicles
I’m not certain how many cities actually have these Red-light Cameras installed, but they are designed to photograph anyone who enters the intersection after the traffic light turns red. Believe it or not, these have been around for more than 40 years. My thought is this: How many resources are involved in removing footage of emergency vehicles (Police, Fire, Volunteer Fire, EMS, etc) as they are probably captured several times a day with this system? Is there someone employed by the city to check each photo? Are these emergency vehicles emitting some signal that tells the cameras to ignore them as they blast through the intersections? What do you think?

I wonder if they pick up the signal that most emergency vehicles emit through a device, which allow them to change the traffic signals. As usual, the best info is on Wikipedia!

I think the coppers have a gismo that turns the lights green quickly….
