NightCrawler said it best ... "Prepare your shoulder scene with roadside safety flares (Orion or any brand) to identify the scene."Sure, it takes a few seconds to place flares, but, In the same manner, TIM, teaches responders to place cones or flares. Flares, because of their incredibaly bright, piercing flourescent light, is an international sign of distress or a notification that something is going on. While I like the idea of having a blocker truck on-scene, look at the history of having either a blocker truck or police vehicle on-scene, but somehow, distracted motorists impact the blocker vehicle or police vehicle. Not all companies have the extra trucks or assets available to include blocker trucks, but, every truck should be equipped with 180-minutes of burning flares (thats the minimum requirement by the California Highway Patrol. Since data proves that most tow operator fatalities happen during night-time hours, brightly identifying the scene make most sense. Making the excuse that it takes too long or flares are expensive is a crap statement as far as I'm conderned. The investment in a case of flares is chump-change versus losing a driver. And, when it comes down to a court setting, the question will ALWAYS come up, "What, Mr. Tower, did you do to illuminate the scene other than simply turning on your over-head emergency lights?" When your answer is, "Nothing", there's a good chance a jury will find you at fault. Let lessons learned lead us to a smarter way of defending our actions than doing nothing at all. Six California cases that I've been involved in will tell you the same. You're not going to elimitate distracted or drunk drivers, but, a proactive stance (on the tower's part) may save your company's hide somewhere down the road. And, if you look at the majority of tow operator fatalities, there's a gigantic number of tow operator fatalities where NO flares, cones or traffic control were present. This isn't rocket science, but, it is a change in survival mentality. Ask youself, "What can you do on-scene to make the tow scene more visible to approaching traffic, especially in those incredibally dark, rural areas. You are in-control. Do something to illuminate your presence and STOP THINKING that the motoring public is going to move-over for you. R.
