The Graff Mount Pleasant blog offers a number of tips for safe driving in wintry conditions.
Safe driving begins with cleaning off your vehicle before you drive. Clean ice and snow from windshields, all windows, headlights and brake lights for the best visibility. Clean windows completely rather than just one tiny area, as that isn't safe. Clean piles of snow off the roof, too, so the snow doesn't slide down onto the back window or end up on someone else's windshield.
Drive slowly when roads are covered in snow or ice, slush or look dark, as black ice may be the culprit. Roads can ice up in a hurry. Slow driving allows more time to react and brake when necessary. Also leave plenty of space between your vehicle and the one ahead of yours, so you can brake or veer around it, if needed.
Never brake abruptly in snowy or icy conditions, as this could cause the car to slide or swerve. Instead, coast and slowly, gently apply the brake. Likewise, forget about making sharp turns in poor driving conditions. Instead, ease your way into the turns.
Cruise control also should not be used when the roads are covered in snow, ice or slush, as you won't have optimal control of the vehicle when you need it most.
Keep an eye on weather and road conditions by looking at forecasts and at webcams installed on major highways. Many state departments of transportation offer such sites, which can show you real-time road conditions before you venture out.
