Which parts of your motor vehicle do you have to completely clear of snow and ice before driving off?

You answered correctly. Before driving off in winter, you must fully clear the windscreen, exterior mirrors, and side windows of snow and ice. This rule ensures that your visibility in all directions is not restricted, allowing you to see other road users and react safely. Driving with obstructed windows or mirrors is dangerous and can lead to fines or accidents. Always make sure that all relevant glass areas and mirrors are completely free of snow and ice for your safety and that of others.
