Right on schedule, the grim weather hazard of road ice is already taking hold this season. The past week has brought the season's first snowfall to many parts of the country, and with it, the first multiple-fatality and injury accident reports. The toll from road ice this week has reached at least 15, with news feeds lighting up with reports of multiple fatal crashes in numerous states. The following is a list of this past week's incidents so far, and more reports will likely come in over the next few days. Many of these have resulted from an early-season snow event in the northeastern US states.

Five of these fatalities involved the secondary or 'follow-up' crash phenomenon, where motorists (either Good Samaritans or accident victims) were struck by a subsequent out-of-control vehicle after standing outside on the roadway. The victims were outside either checking on another driver or inspecting the damage to their own car. These are five more tragic examples of how the first icy road accident scene is still actually an accident-in-progress situation, and as such, it is critical to everyone involved to either remain in their vehicles or get as far off of the roadway as possible, as quickly as possible. Further out-of-control cars and trucks are almost certain to be approaching, with no way to avoid a collision with someone standing on or along the road. If stranded motorists are unable to get away from the road (as in the middle of a bridge), a car's interior provides a more survivable collision protection than standing outside.

As a result of research of events during the past few winter seasons, I've noted that injury and total accident numbers can be very loosely estimated from the number of deaths. During a typical event, for every death recorded, there are 50 to 150 injuries; and anywhere from 400 to 1,000 accidents serious enough to be reported to police. I prefer to be conservative when estimating numbers to avoid any appearance of exaggeration, so I usually use the lowest possible multiplier: That yields formulas of Injuries=50x deaths and Accidents=400x deaths. So without painstakingly counting every single injury and damage-causing accident using police reports, we can roughly estimate from this ratio that at least 750 injuries occurred this week, with at least 6,000 vehicles damaged. Again, those are minimum numbers using a conservative estimate - they are likely much higher in actuality. Assuming an average damage loss to a vehicle of $8,000 (some cars totaled, others dented/scratched), the economic loss from vehicle damage alone for this week is likely more than $48 million. That does not include medical expenses for the injured, tow truck fees, police/fire/EMS overtime/operating costs, and lost work time/productivity from those injured or having a damaged car to deal with.

15 deaths. 750+ people hurt. $48+ million in damage. And it's only November 4, folks. That's the road ice hazard, and that's why this web site exists. We have a long winter ahead. Let's see what we can do to make a difference this season.
