How can you achieve sufficient visibility through the windscreen?

You answered correctly by choosing the first two answers. To maintain good visibility, it is important to use your windscreen wipers during foggy conditions because moisture can quickly gather on the glass and reduce your view. Also, when you drive in slushy conditions, turning on the wipers before slush gets thrown onto your windscreen helps clear your view immediately and prevents unexpected vision loss. The third answer is incorrect because, if the windscreen is steamed up, you should actually use ventilation or open a window to remove the condensation. Keeping the ventilator off and the windows closed would make the problem worse. Remember, good visibility is essential for safe driving, so use your wipers and ventilation as needed for weather conditions.
