Snapchat is facing a lawsuit following a high-speed car wreck in which one of the drivers may have been using Snapchat.

The accident left the former Uber driver with permanent brain damage.

The lawsuit demands unspecified damages from Snapchat, a five-year-old company valued at $16billion (£10.9million).

Maynard claims the crash was caused by a new Snapchat filter which encouraged Christal McGee to speed, court docs claim.

Maynard and his wife were merging onto a highway near Atlanta, US, on September 10 when they were struck.

McGee was speeding at 107 mph while taking selfies with Snapchat’s speed filter.

The app awards a “trophy” to users who post pics showing off their speed.

The suit argues the filter “facilitated McGee’s excessive speeding” and “distracted” her in the moments before the crash.

McGee kept snapping even after the crash.

Maynard’s lawyers show McGee in the ambulance with blood running down her face under the caption: “Lucky to be alive”.

Maynard has been unable to work since the accident.
