Back in April, Lyft launched features that made its system easier to use by deaf drivers and those who are hard of hearing. Now, it's adding a couple more to celebrate National Deaf Awareness Month. Thanks to its partnership with the National Association of the Deaf, the ride-hailing firm has developed "flash-on request" for drivers. If they've activated the app's hard-of-hearing accessibility function, they'll get a powerful visual notification whenever a ride request comes in: their phone's screen and flashlight will both light up. When combined with the Amp emblem flashing the words "New Ride," it could lower the chances of a driver missing out on a request.
