Fact: I carry a book with me that tells me how to lay out safety break down triangles or flares, it covers blind curves, straight highways, hills and both one and 2 lane roads. This book is REQUIRED READING for professional drivers but optional for me.. Still I carry it, that's why.
I also have the document on my hard drive (The section that covers flair placement).
Where can I get a copy of the book and the file that you have on your hard drive?
Found this on http://ice4safety.blogspot.com/2009/...ad-flares.html
Flares should be positioned in a tapered pattern to direct vehicles away from behind your vehicle. Using flares on the opposite side of the roadway at the scene of a crash can help delineate the accident scene. Inclement weather (usually the accident cause) can hamper the speed of your deployment.
To determine the placement of the first flare (furthest from vehicle) use the posted speed limit - convert that to feet then multiply by a factor of 4 - (30 = 30 x 4 or 120 ft)
If the speed limit is over
50 mph, then multiply that speed by 4 and add
100 to get the distance ( 60mph = (60x4) +100 =340ft). On a curve add the distance from the bottom of the curve to the top of the curve and add to the distance calculated. A chart might help:
30 mph ----- 30 ft ----- 120 ft
40 mph ----- 40 ft----- 160 ft
55 mph ----- 55 ft ----- 220 + 100 = 320 ft
65 mph ----- 65 ft ----- 260 + 100 = 360 ft

If you are off the road on the shoulder out of traffic that is ideal although not perfectly safe as accident statistics and prior experience has shown us - but better than in the high speed traffic lane. Placing yourself in high speed traffic without any professional assistance in an effort to manage traffic can get you seriously injured or worse.
