Protagonist, Sorry about your friend. We have had two cops killed at scenes (I wasn't at either) from jerks blasting through 10,000 CP of strobes going here in last several years.
I forgot to add when possible we (fire dept) will close road down for several hours and establish road blocks up to several miles in each direction to divert traffic around and they don't even come through our scenes and avoids lines backing up as well.
Also be extremely leary of topping a hill and seeing a wreck on defilade side. Stop and get off road way back from the scene as such conditions cause lots of wrecks especially on interstate routes.
Haven't had to do it yet but my plan from now on is pull off quickly, hit the flashers as close to the top of the hill as I can and if I have the AS hooked up I will go back to bathroom and hook up my fire dept wigwag red lights in the 12V
recepticle over the sink and aim it out the back window.
We are also told our insurance won't pay off if we get hit and don't have on a DOT approved vest.
I have also seen reflective trousers (same colors) and just found out the official name of the color appears to be NEON GREEN.
I have had a policy for years going through a scene to slow down to no more than 10 MPH and have my flashers on as well and watching for all movements.
We all know from pulling our trailers we have to have a different mind set because when you hook to a AS you had better be ON YOUR GAME.
Brings to mind another warning I got from a guy I met from Canada who comes to the states and hooks up new trailers and pulls them back and delivers them all over Canada.
His advice was to never tow a trailer faster than 60 MPH as that is about as fast as you can maneuver.
He said the other trailer haulers rag him on CB about going so slow and they blew past him at 70MPH for better and he has found them rolled or wrecked miles down the road. He drives about 90,000 to 115,000 miles per year and will tow with nothing less than a 1 Ton Dually.
A couple weeks ago I stopped by a dealership here and he had a 77 Sovereign
on his lot and it was gone. I was interested in it and he said the guy that bought it hit the road with it the next day and rolled it and his tow vehicle as he had no experience towing heavy trailers.
One other interesting note. I changed out the dome interior light on 2007 GMC 2500HD and installed two BLUE LED panel lights. I had to solder wires together to rig two sets. Makes for a very bright internally lit cab at night and the best part is the Colors BLUE, RED OR GREEN on DO NOT destroy night vision like the white lights do.
I got the panels on ebay and they have 3M sticky tape adaptor to use the GMC recepticle thusly one panel is directed left and the other right. Two of them delivered were like $5.00 and we like them very much.
