Lyft drivers are individuals who use their personal vehicles to provide rides to passengers through the Lyft app. They can work flexible hours, choosing when and how often they want to drive. To become a driver, one must meet certain requirements, such as being at least 21 years old, having a valid driver's license, and passing a background check. Drivers earn money based on the distance and duration of each ride, as well as tips from passengers. They can also benefit from various incentives and bonuses offered by Lyft to encourage more rides during peak times.
