I work for AMR in Lancaster/Palmdale and we have something like 4 or 5 of those lights. We dont have many center medians here so when people dont move we can just oppose. I do love the cameras, gotta pose and say cheese. While on the subject of drivers, when people see an ambulance in there rearview mirror why is it they panic like its armagedon? They just cold stop in the middle of the road or pull to the left and not the right......Ill never understand it. But I had a officer follow me the other day and gave a ticket to a dummy that stopped in the middle of the road instead of pulling to the right. Awww gotta love it.
