Turn your headlights on. When you cannot see a distinct reflection of them on the snow in front of you, stop. I got used to automatic headlights coming on when I entered the garage - granted, it's dark in the garage, but when you no longer see the bright light reflected back at you, it's time to stop (usually about a foot or so away from hitting anything). I've found it works the same in daylight in parking where I work, as the spot where I park is up against a solid barrier.
Well, I’ve never hit the snow bank. It’s my husband every time. He’s probably just distracted. And the lights are always on when the engine is running and we’re in gear — can’t say that I’ve ever noticed them reflecting on the snow. I’ll be sure to check the next time it snows and we have enough accumulation to provide a barrier!
I nag him now when he is pulling in about stopping a little short. Hopefully he’s learned his lesson. LOL.
The funny thing is that we had those 2 LHSs. They had this huge engine compartment with the nose of that car hanging way over the front wheels. I’d pull into a space and advance until the front tires just bumped the curb, get out, and find that the front of my car was almost completly covering the sidewalk! I never cracked that bumper, although you’d think that I would at some point in over 200,000 miles. (We drove both of those cars that far — in fact we still have one of them — 229,000 mi. Fin, fine cars, if you ignore the transmissions that had to be replaced every 60,000 mi.) In fact, if I could have found a used LHS with about 30,000 mi. on it, I never would have bought the Caddy. Somebody who works at McDonalds at night in the next town is driving a twin to my former LHS — I’ve often thought to ask if they want to sell it.
