Drive slow and steady. Just because you know how to drive in the snow doesn't mean others do. Take your time and be courteous to other cars. Arriving safely is more important than arriving quickly.
Use your turn signals. Roads are narrow with snow banks, so let others know you plan to merge unexpectedly.
Check your car before you go. Do you have windshield fluid, a shovel, and an ice scraper? Be prepared before you hit the road.
Safety first. No matter what the earnings and demand, keep safety as your first priority.
