Are working washers a legal requirement?

Yes — vehicles must be able to clean the windscreen, so functioning wipers and washers with fluid are required, not optional.

How do I know if a blade needs changing?

If it smears, streaks or leaves unwiped areas, replace it — worn blades are one of the most common and cheapest defects to fix.

What fluid should I use?

A proper screen wash, especially in winter, so it doesn't freeze and it clears grime and salt spray effectively.

In short

The daily wipers-and-washers check confirms the driver can keep a clear view in rain and spray. It's a quick operation check plus a look at blade condition and fluid level, but it's a legal requirement, not an optional extra.

When to fail it

Fail the item if the wipers don't clear the screen effectively or the washers don't work — a vehicle must be able to maintain a clear view in poor weather.

Why it matters

Driving without a clear view in rain or spray is dangerous and can be an offence. It's a cheap, quick fix that prevents a roadside issue.
