Driving in Bad Weather and Low Visibility
Your task as a safe driver is to know how to adjust your driving to meet conditions on the road when you must travel, or to know how to maintain a modicum of safety when you find yourself in bad weather.
Your ability to see is limited in adverse weather conditions such as rain, fog, ice, snow, and dust. The most effective defensive driving techniques in these cases are to slow down and drive at speeds safe for the weather or to delay departure until conditions improve.
Bright sun or light reflections on a dirty window decrease visibility and increase risk. You should clear ice, frost, or dew from all windows before you drive.
Make sure you are able to see and be seen. If you drive in rain or snow, make sure to stop sometimes to wipe mud or snow off your windshield, headlights, and taillights. In any case, even in excellent weather, drive with your headlights on so as to be seen by other drivers.
