191. Windscreen wiper

A windscreen wiper is a device that removes rain, snow, dirt and other moisture from a vehicle’s windscreen to maintain a clear view of the road. Most vehicles use electrically powered wipers with replaceable rubber blades and several operating speeds, often together with a windscreen washer system. Drivers should replace worn or damaged wiper blades when they leave streaks, skip across the glass or no longer clean the windscreen effectively.

What is a windscreen wiper?

A windscreen wiper is a device that moves across the windscreen to remove rain, snow, dirt and moisture so the driver can maintain a clear view of the road.

Why are windscreen wipers important?

Windscreen wipers help maintain clear visibility in bad weather and when the windscreen becomes dirty. Poor visibility can make it harder to detect traffic, pedestrians, signs and hazards.

When should windscreen wiper blades be replaced?

Wiper blades should be replaced when they are worn, cracked, damaged or no longer clean the windscreen effectively. Common signs include streaking, skipping, squeaking or areas of the windscreen remaining wet.

What is the windscreen washer system?

The windscreen washer system sprays cleaning fluid onto the windscreen so the wipers can remove dirt and improve visibility.

Can you drive with broken windscreen wipers?

Driving with defective windscreen wipers can be unsafe and may be illegal where functioning wipers are required. The driver must be able to maintain adequate visibility through the windscreen.

Do cars have a rear window wiper?

Many vehicles have a rear window wiper, especially hatchbacks, estate cars and SUVs. Whether one is fitted or legally required depends on the vehicle design and applicable regulations.
