Driverless trucks are officially running their first regular long-haul routes, making roundtrips between Dallas and Houston.
A Texas sheriff's office almost 90 miles away from Houston said as many as 82 of those people left the tractor-trailer when it broke down Friday morning.
The driver is believed to have fired shots toward a woman he was dating before jumping into a big rig and taking off.
The driver was headed from the Southwest Freeway to the loop when his load shifted, sending his truck over the guardrails.
Witnesses said the driver was swerving in and out of lanes and "leaned back" in the car moments before he rammed into the back of the trailer.
An 11-month-old baby is among those passengers who survived the crash.
