Ninety percent of all driving decisions are based on a clear unobstructed view of the road, which means good visibility is absolutely essential; especially during wet weather when vision may be obscured by water, road splash, sleet or snow on the windscreen. But good visibility requires wipers that are in good condition.
There's nothing more satisfying than the clean, clear efficient sweep of new wiper blades. It's amazing how often people leave it until it's too late. If you find yourself straining to see through the spray or wincing as your wiper blades screech across the windscreen then it really is time to get a new set.
