What indicates that a wiper is performing well on low speed?

A wiper performing well on low speed is indicated by a rate of 15 cycles per minute or more. This rate reflects an efficient operation that ensures adequate visibility during inclement weather. Wipers must clear water and debris effectively to provide a clear view of the road, and a minimum cycle rate is essential for this purpose.

While a lower cycle rate, such as less than 10 cycles per minute, would suggest that the wipers may be underperforming and could impede visibility. Additionally, operating smoothly is important, but it does not provide a complete measure of performance without the context of the cycle rate. A good performance standard is important for safety and compliance with inspection criteria, and thus a higher cycle rate indicates that the wiper system is functioning effectively at low speed.
