So you just woke up, downed two shots of Bourbon and you’re ready to go wander around an outdoor shopping area or whatever it is you do with your pathetic self. You look outside to find that there’s mysterious white stuff falling from the sky. Don’t panic! Put down the Wild Turkey and read the following tips for surviving the wintry carpocolypse.
Clear Windows > Snow-Covered Windows
So you made it out the door and the Sherrif/Repo man is nowhere to be seen. Before getting in your Malibu, it’s important to brush the snow and ice off of your windows. Nothing is going to turn a good day bad like wrecking in your parking space because you couldn’t see and didn’t want to invest 3 bucks in a scraper brush.

Yes, this means you.
Spinning Tires > Locked Up Tires
This point might seem obvious be a little tricky to understand, but spinning wheels have significantly more traction than wheels that are not spinning, just ask the guy in the snowbank. The reason for this is actually pretty simple physics rocket science. Imagine that a spinning tire is not actually moving in relationship to the road, whereas a skidding tire is. The traction is significantly greater for the spinning tire (not moving in relation to the road) than the skidding tire (moving in relation to the road).
Moving > Being Stationary
So you made it out of your driveway with clean windows and spinning tires, you’re already well on the way to having a good time. But oh no, there are some things blocking your way (drivers that didn’t read this post and are stuck in the snow bank). Do whatever you can (within reason and safety) to keep moving. Another little physics lesson: It takes less effort (work) to keep an object in motion that is already in motion. Remember how traction is greater when the tire is not moving in relation to the road? Well now the same thing that keeps you rolling straight when you’re moving is working furiously against you to keep you from moving and you don’t have any traction because of those bald tires, which brings us to the next point.
Snow Tires/Chains > Bald/Summer Tires
If you anywhere that has a lot of snow (North of the Mason Dixon Line, the mountains, Mother Russia, etc.) you should consider snow tires during the winter. Skip on to the next point if you’re already a little overwhelmed, because this next bit is complicated. When you’re skidding on ice it’s because of two main factors, 1. the friction coefficient we’ve discussed on end and 2. hydroplaning. Hydroplaning is what happens when water sneaks in between the tire and the road and causes the tire to move in relation to the road (sounding familiar?). Snow tires help you get better traction by 1. increasing the initial friction coefficient (by being made of a softer material) and 2. providing more options for that water to escape. They won’t stop skidding if you try really hard (which I imagine you are), but they will significantly reduce it.

Don't be this guy.
AWD/4WD > 2WD
Now you’re probably saying, “You can’t roll in a Subaru with dubs.” Yes Mr. Stereotype, this is probably true. However, there’s a reason all those people driving Subarus are not buried in a snow bank. Another lesson perhaps? Let’s say an engine has X amount of power, 92bhp like your CRX does. When you try to lay that incredible power down through the front wheels only, you’re towing the back wheels like deadweight (remember trying to overcome that static friction?). However, when all for wheels have power going to them, each wheel is overcoming the dreaded (or celebrated) static friction and moving the car forward more easily.
More Weight > Less Weight
Of course you already knew this, didn’t you, fatty? Remember the guy in the pickup from before?

Yeah, this guy.
Another factor influencing your traction is weight. A vehicle with more weight exerts more downward pressure on the road (on account of gravity, a lesson for another day) and increases the friction (assuming the wheels are spinning) between the tires and the road. So while your manly man’s pickup might have 4WD, it won’t do you a lot of good if you’ve got the equivalent of a midget pushing the back wheels down.

Your pickup's traction solution.
The simple solution is to add some sand bags to the bed, or more midgets, whatever is easier to come by.
Being Smart > Being An Idiot
So let’s say you’ve got a car or truck with 4WD/AWD, clean windows, snow tires and an even weight distribution/team of circus midgets. Well, you probably don’t really need to know this because you already graduated from Basic Driving Knowledge School (not required to receive a driver’s license in the US). But driving in poor conditions is dangerous, and it’s not just because of you or the drunk idiot in the Malibu with bald tires going 70mph. It’s dangerous because 95% of the other people on the road are just like the idiot. So try as you might, you will probably get stuck or wrecked because of at least one of these people (probably more). The easiest way to stay safe out there is to NOT GO OUT THERE. Settle down with that bottle of Wild Turkey and turn on the Xbox, you’ve got a long day of fun ahead of you!
