There have been at least three of these 100-car pileups this winter .
I suspect that many drivers don't understand the threat that ice poses and, as a result, they drive in risky conditions even when they don't have to .
People sometimes wait until their tires are worn down to the wear bars before replacing them ; newer tires make a world of difference on ice .
A cold road can freeze over suddenly from contact with fog or drizzle .
People used to going to work at 80 MPH in the rush hour have a hard time adjusting their speed far down when ice could form . As a result, interstate traffic moves too fast and everyone is forced to go too fast to keep up .
I bet it would be more economical for big trucks to stay off of the roads on hazardous days than to pay the costs of accidents . The trucks present a problem because their heavy weight gives them better traction than the cars have ; The trucks go fast, the cars try to keep up, the cars skid, the trucks can't stop...
The phone app, " Trapster " may be a help for sharing timely warnings of ice and accidents .
AM/FM radio station traffic reports are often late or inaccurate .
Before you start out, brush and scrape snow and ice off of the entire car . Take off bulky coats so you can drive more easily . Make sure have plenty of fuel in case you must idle a long time in a traffic jam . Check the weather reports and the thermometer on your instrument panel .
To avoid problems : Drive slowly enough and keep right to allow faster traffic to pass safely . Avoid stopping completely so you have momentum to carry you over slippery spots . Leave a very long following distance . If you get behind a slow-moving vehicle, use your flashers to warn those behind you that you are going very slowly . Don't pass snow plows . Be cautious popping over hills and in other areas where it is hard to see traffic stopped ahead . Expect icy spots under and on bridges and overpasses, at mountain tops and on exit ramps .
Add weight to your car for better traction . Carry flares, traffic cones, beacons and reflective triangles to warn traffic should you get into an accident .
Try to run a set of good all season tires that match . Some may prefer snow tires .
If you know a storm is coming in the morning, consider driving to work the night before and sleeping there . Keep extra clothes, toiletries, snacks and bedding so you can stay after work if need be ; better than getting stuck in a snarled rush hour gridlock .
