Winter can be nasty for sure , it’s knowing when to push on or pull the curtains . My lot would rather we get there than not and pay us to park if we feel it’s warranted , dispatch will never hassle us to move the load . I parked once last year running empty between Portage and Winnipeg because the truck was steering itself and my attempts were futile(worst piece of road in Canada IMHO) . Down to common sense , if you’re not comfortable park up before you become a hazard to yourself and others . Winter certainly has its moments from hell but it’s not bad all the way through , day after day .
