Visibility while driving in the rain is of utmost importance. A few tips:

• Keep windscreen washer fluid topped up at all times.
• Keep both sides of the windscreen clean. Cleaning in circular motion with a newspaper will yield best results.
• If the front windscreen fogs up, turn the AC on and direct flow onto it and the window glass, if necessary. If it's a non-AC car, lower the windows a fraction.
• With rear glass fogging, use a defogger or turn on the AC. Lowering the windows will defog the rear glass too.
• If you wear spectacles remember that they are your primary glasses. Keep them clean and then worry about your car's glass.
