Why is it important to clear all ice and snow from your vehicle before driving in winter?

• To avoid scratches on the vehicle surface
• To prevent gas line freezing
• To ensure proper aerodynamics
• To prevent ice and snow from blowing into vehicles behind you
  Explanation:

  "Remove ALL ice and snow from your vehicle before driving. Clear all windows, windshield wipers, headlights, and brake lights. It is very important that you clear the roof, hood, and trunk so ice and snow do not blow into vehicles behind you. If you do not, you can be charged with negligent operation."
