Five people were injured and westbound I-90 traffic slowed west of the Zoo Drive exit in Billings Tuesday evening.
A four-door passenger car was heading north on Duck Creek Road when it didn't stop at the intersection with South Frontage Road around 8 p.m., according to Montana Highway Patrol Trooper Eric Gardner. Traffic was slowed to one lane.
The vehicle was carrying three children and two adults. All five were transported to a Billings hospital with minor injuries, he said.
The vehicle flew across four lanes of interstate traffic, rolled over, and ended up in the ditch on the north side of the westbound lanes, Gardner said.
Speed and alcohol are considered factors in the crash, according to Gardner.
Billings firefighters, AMR ambulance, Yellowstone County sheriff's deputies and Montana Highway Patrol are responding.
