They do fine to a point depending on the model of trike. Granted, they can't topple over, but my rear derailleur has maybe 1.5 inch clearance. Snow can choke and freeze the chain or worse, on the cycle paths, hard ice with deep ruts from bikes when it was soft can smash the derailleur to bits if the rear wheel slips into a ice groove.
I lost two of them before I gave up on riding once things get too icy.
