I'm a native New Englander so this sort of weather is pretty much the norm. I might be teaching your granny to suck eggs, but some tips for driving in this weather:
- Keep a spade/shovel in your boot
- Keep a couple of door mats in your boot
- If you get stuck, immediately stop accelerating. If your wheels are spinning, keeping on trying to move forwards just creates heat below them which then turns to ice
- Instead, try to rock the car out by reversing then pulling forward. Turn your wheels a bit if reversing straight doesn't work. ETA: Sorry, to be clear, turn your wheels while stopped & then reverse, not turn the wheel while trying to reverse.
- If that doesn't work, use the spade to dig out the wheels.
- If that doesn't work, identify which tyre is spinning and stick the door mat under it.
- If that doesn't work and no one is around to help push you, I give up!
Remember, high gear, low revs (for getting unstuck) and very very gentle acceleration.
