Here is a photo from what happened this morning. As you can see, there were guardrails along each shoulder and nowhere for them to go but smash into the car in front of them. Because 4-wheel drive or not, you are not going to stop in time if you are driving at highway speeds and suddenly see a wreck in front of you.

I've driving I-93 many times (from Boston area up into NH) and that can be a dangerous highway even in good weather. Especially when you get into New Hampshire. It's mostly just two lanes in each direction and there can be many miles between exits and people just drive too damn fast.

I was involved in a chain-accident like this many years ago during a snow squall and it's quite a scary experience. Fortunately I was able to drive off the shoulder and avoid a collision but it was almost two hours before the traffic started moving again.

WMUR out of Manchester says a whiteout snow squall was the cause of the chain reaction. Nobody could see.
Everybody must have been in a hurry to get to Loon or Cannon Mtn.
