Prime Time is Lyft's version of Uber's surge pricing, which is measured by percentages instead of a multiplier.

"Prime Time varies based on supply and demand and can change from second to second," according to the Lyft website.

A 200 percent Prime Time on Lyft is equal to 3x surge pricing on Uber.

Lyft ended the cap and co-founder John Zimmer mentioned it in a January blog post to drivers, but users say they were not notified.

The post said the percentage cap would only be used in emergencies.

Users have shared stories about dealing with exceedingly high Prime Time rates on a popular ride-sharing forum in January.

Some said they had a Prime Time rate of 250 percent to 300 percent.

The Lyft blog does not appear to have information targeted toward users announcing the removal of the surge cap.
