A couple is suing Snapchat, claiming that the social media app’s “speed filter” tempted a woman to drive too fast, causing a crash.

Media outlets report Wentworth and Karen Maynard filed a lawsuit in Spalding County state court against Snapchat and 18-year-old driver Christal McGee.

The lawsuit says that in September, Wentworth Maynard was driving down a highway in Hampton, south of Atlanta, when McGee was driving using a Snapchat filter that places the rate at which a vehicle is traveling over an image. The lawsuit says McGee was trying to go 100 miles per hour.

McGee’s car struck Maynard’s car, sending Maynard’s vehicle across the left lane and into an embankment.

The lawsuit says Wentworth Maynard suffered brain damage.

Snapchat representatives didn’t comment on the lawsuit. It’s unclear if McGee has an attorney.
