I got popped by one of those awhile back ... while driving an ambulance, transporting a patient (more on that later) ...
Here's what I learned when I went in to fight it ...
First off, I was sent, actually my company was sent, a notice of the infraction, which had four different photos attached. One was of the area of me entering the intersection AFTER the light had changed to red along with a time stamp of when the camera went off of when I was "caught". Two others showed the front and rear license plates of the vehicle (sic ... Ambulance) I was in and lastly, the forth one was a photo of me driving. This is for ID purposes.
I was then directed to go to the City's (Denver) web site where I could watch a video of the me entering the intersection. The video starts when the light cycles to yellow and continues on for approximately four seconds after the light cycles to red.
Here in CO, yellow lights MUST remain on for four seconds after cycling from green. If they don't and you're nabbed "running" a red light, you can get that infraction dismissed.
Also too, you must come to a complete stop at the stop line (solid white line before the intersection). Either before it or your front tires "landing" on it. There were several people in court who did stop for the red light, but were either in the cross walk or past it. Judge said "Nope. You must stop at the stop line. $75.00. Pay the cashier as you leave. Next."
So, if you or you know of anyone (family, friend, etc.) who does get nailed, make sure you can view the tape and get the information of your area, about how long the yellow light needs to remain on before cycling to red.
These things have been fought over around here for years. Studies have shown that they do NOT decrease accidents at intersections, but that they increase them. As stated above, people slamming on their breaks (brakes) when the light cycles, or "riding" their breaks (brakes) when entering an intersection and the light is still green. It's been shown that these things are nothing more than revenue generating devices. NOT safety devices. But the current Dem/Lib/Progressive/Socialist government currently in power here in CO, don't want to get rid of them. Go figure.
Now, on to my incident ....
Picked up a patient who was in pretty rough shape. Before taking off towards the Hsp. I asked my partner if he wanted to go emergent? He thought about it for awhile, which means that we should have, but he said, "No, make in Non ... But we might be stepping it up later."
This was for the fact that my partner was alone in the back and was busy, and I MEAN BUSY, working on this guy, and with the jostling of the rig while going emergent, it is a pain in the ass while working on someone. Besides, we really didn't like driving emergent, not because of the that, but because of the other drivers LOOSE THEIR FREAKING MINDS when they see an emergent vehicle (EMS, Police, Fire) which actually causes a danger when we do.
Anyway, as I was driving, I approached this intersection and saw the light cycle to yellow and started to apply the breaks (brakes), as was seen in the video. The thing is, this intersection where this camera is at, is at the bottom of a small hill. Stopping a large vehicle like an ambulance, especially on a downward slope, does not come easy. So, I applied the brakes (didn't have to change this one

) a little harder.
As I did, I heard a loud "WHOA !!!!" from the back and glanced up to notice my partner was standing up over the patient "working" hard. Again, that silly physics thing comes into play. Had I stopped, I very well could have "thrown" my partner into the wall. I had done that to one previous partner, this time someone cut infront of us as we were proceeding through an intersection, thusly ending her career with back problems, I wasn't about to do it again. Also too, that current partner had RA and had had a hip replacement years prior, so I wasn't about to end another career.
The tape showed that I entered the intersection when the light turned red at approx. 0.43 seconds. It's not like I was deliberately trying to run the light.
Well, I went to court to fight it, but the judge said "Sorry, you did get caught running a red light, but since you were transporting a patient, I'll knock $20.00 off. Next"
Not only did I have to pay that fine, but due to company policy, I ended up with two weeks on the beach with no pay. But that's okay ... I got my pound of flesh from them later.
