[header] How to increase driving visibility in rain [title] Turn your windshield wipers on. [step] Unless your car comes with automatic wipers, you'll need to manually activate your windshield wipers to improve driving visibility in the rain. Windshield wipers typically have three different settings: slow, medium, and fast. 
If the rain is light, select the slow speed. If the rain is heavier (and your visibility is poorer), select a faster speed.
