Have y’all heard this saying? I hear it every year around this time.

But what do they mean when they say it?!

Option A
It’s the first day of snow and everyone is driving way under the speed limit and way too timidly because they have forgotten how to drive in the snow.

Option B
It’s the first day of snow and everyone is driving like they normally do because they have forgotten that you have to slow down and be cautious when driving in the snow.

If you say this or come from a family that says this, could you tell me what it means? I feel like proper use of this phrase is a major part of my assimilation into Minnesota culture, but I really need to know what it means first.
