Wow, so I somehow managed to survive the "great blizzard of '09" here in Raleigh! I'm always amazed at the panic that even the mention of that 4-letter S word brings on. Why bread and milk anyway? Personally I prefer hot wings and beer especially when there's a great game like the Duke/NC State game on! Anyhow, when I was watching the news after the game, they mentioned about how there were over 100 car accidents in the area. This is absolutely absurd in my opinion! Insurance companies are racking up on premium increases because of you! Now, I'm not claiming to be the definitive authority on driving in the snow but I do have a few tips for for those who are interested!
This is the summary of sll of the tips to follow in one phrase USE COMMON SENSE!! Here's how:
Know where you are going and how to get there before you even leave your house. If you don't know where you're going, you probably don't need to go there in a blizzard. Unless it absolutely can't wait until the next day don't even try to go out! If you do have to get there know how you will get there! The worst thing you can do to other drivers is almost miss your turn and try to correct by trying to slam on breaks or cutting them off! This leads to my next tip!
Don't use your breaks! Of course you will need to break at stop lights and such but I'm talking about when you're driving down the road, quit tapping your breaks! All this does is create an opportunity for your tires to loose traction. Use the natural laws of physics to slow you down or better yet DON'T GO THAT FAST IN THE FIRST PLACE!
Be aware of other cars (stupid drivers) on the road. Even if you're comfortable with driving in the snow, the guy driving next to you might now. I'd hate to see that car do something stupid and slam into you! Keep your distance. Even when stopped a traffic light keep your distance because if that guy rear-ends you and forces you into the car in front of you it's now your fault for that guy and your insurance is going up!
Remember Newton's Law of Inertia. This gets into the technical physics of it all. But here is the law: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. And here it is explained: Basically your car want to follow the straightest path and go at the same speed unless another force (friction in this case) acts on it. This applies everyday but you have to think about it more on snow. Under normal circumstances we have the force of friction acting on our side (dry road + rubber tires = lots of friction). Now, on snow we lose alot of the friction and on ice it's almost non-existant. So, how do we compensate? Keep the turns to a minimum. your car wants to go in the straighest path as possible and when you tell it to turn you are changing the force and it doesn't like that, friction is what causes it to react. When there is no friction, motion will laugh at you and keep going straight (into the tree or ditch). The law also says that motion likes to keep going, it doesn't like to go away (slow down). So, remember my braking comment? This is why. Even though you want to slow down or stop, motion doesn't and when friction's not on your team, motion wins because there's no external force acting on it.
I hope these few tips helped out. Bottom line is be smart about it and use some common sense as I mentioned before. If you have never driven in the snow, get someone who is experienced to take you to an empty parking lot and practice! Know how to recover from a skid, how to avoid skids in the first place, and how much distance is truly required to stop compared to normal conditions.
Be safe, enjoy the snow, and never enter a snowball fight with the local baseball star!
