All due respect to the OP, but this advice this makes absolutely no sense to me.
Why take a break when this is just the type of experience you can use to become a better more confident rider and really learn about your route options?
I've been on vacation these past weeks... I'm done my break from commuting and I'll be riding in the insanity that is back to school week next Tuesday. But as others have mentioned the worst driving is always during the first snow storm.
I live in a university town. The only difference I notice is more glass on the roads (broken beer bottles, mostly) and more riders salmoning in the dark with no lights.
The only time I take a break from commuting is during spring melt. Even studs don't work well on the wet patches of ice on side streets and in shady spots. Winter is easier unless the wind chill is really bad or there's been a lot of drifting snow.
