A powerful new video details true stories of fatal accidents while texting and driving.

“Where U At,” “LOL,” “Yeah,” – they’re hardly the most influential phrases in the English language. But for the drivers in a new video released by AT&T as part of its campaign against texting and driving, reading those few little snippets changed their lives; in fact, they ended them.

From the 18-year-old with cap and gown beside her who jumped a median and hit an overpass bridge head-on (she would have graduated the following day), to the story of how one girl’s text contributed to her sister’s flipping her truck into a ditch, the video contains an incredibly powerful message: Yes, texting is as distracting as driving drunk. It takes lives. It only takes a second to lose control.
