Lyft has lowered its prices in select markets throughout the United States in an effort to compete with its main rival, Uber. Starting today, customers in 33 markets, including San Francisco, Los Angeles, Detroit, Baltimore, and Washington, will see lower fares when using the service.

It shouldn’t come as any surprise that Lyft has followed suit with Uber, as the on-demand car service space has a tit-for-tat mentality. Last week Uber announced it would be lowering fares in 100 cities and here we are with Lyft. Here’s a list of the areas that will benefit from this cut:

Detroit, Baltimore, Bakersfield, Cleveland, Colorado Springs, Cincinnati, Washington, D.C., Denver, Fresno, Spokane, Jacksonville, Los Angeles, Orlando, Memphis, Modesto, Minneapolis-St. Paul, Orange County, Oklahoma City, Omaha, Norfolk, Pittsburgh, Santa Barbara, San Bernardino, San Diego, San Francisco, San Jose/Silicon Valley, Sacramento, Sonoma/Napa Counties, Toledo, Tampa, Tulsa, Indianapolis, and Raleigh-Durham

Depending on the market, riders could expect to see savings between 10 to 30 percent.

While Uber has declined to provide a list of all 100 cities, we’re told that San Francisco, Wichita, Houston, San Diego, Los Angeles, New Jersey, Pittsburgh, Montreal, Charlotte, and Denver are on the list — there is some overlap between Uber and Lyft, which could make things interesting. Could there be a battle in those respective cities to gain the upper hand?

“Lowering the prices are necessary to stay competitive,” said a Lyft spokesperson. “With Uber price changes, we had to protect the ridership and the long-term earnings of our drivers.”

Lyft hasn’t had lengthy discussions with its drivers, but claimed they know the service is “still the best option for them and we only make these changes when we need to.” But while Uber has promised to guarantee earnings for its drivers, there’s no word about whether Lyft will do the same thing; however, there are other programs the company has in place, like Accelerate.

However, Lyft has been rolling out new features and services for its drivers — not only giving them a way to receive instant deposits of their fares, but also benefits at Shell and also Hertz. Yesterday, the company also introduced pre-matching, which is designed to make getting ride requests faster.

This latest battle over who has the lowest fares won’t last forever, but no end date has been set either.
