The coldest days of this winter are still to come, but don't you dare try and warm up your car before you go anywhere — it could cost you big time. Believe it or not, it's actually against the law in both Connecticut and New York to let your car idle, even if it's in your own driveway.

So unless you want to roll the dice and try and avoid a costly fine, you're going to have to avoid the temptation to run out and warm that car up. It's even a bigger temptation for those with remote car starters.

Now law makers don't want you to freeze in the morning — these anti-idling laws were put into effect for a much greater reason — to avoid excess air pollution.

Not only is idling harmful to the environment, but according to Popular Mechanics, with most cars, it's unnecessary. Most experts say that warming up your car does not prolong the life of your engine. In fact, it decreases engine life by stripping oil away from the engine’s cylinders and pistons. The warm up is an old-school method that was needed on cars that had carburetor engines, but does not apply to most of today's vehicles. So unless your ride is a 1978 Dodge, a 30-second warm up is more than enough — the engine will heat up normally when you drive.

So there you have it, two reasons why you shouldn't be letting your car sit and idle while you're getting ready to head out. First, it's not good for your car's engine and second, you might wind up getting an unwanted fine. So dress warm, suck it up and get that cold car moving. You may be chilly for a short while, but it's better than a fine, isn't it?
