I have to post a question here, in my province of Ontario Canada the DOT says the door sticker of GVWR is not what they go by but the GAWR is what they use to determine if you are overweight. My truck...
In BC you are legal if you are legal at home. However, for BCers you must not be over your GVWR. I think Alberta is GAWR like B.C. in B.C. they occasionally check at roadside safety stop campaigns. They have small portable scales. Having said that if it looks level and balanced they leave you alone.
