The Montana Highway Patrol says hazardous driving conditions are expected to continue for the next several days.
They say it's been a busy 24 hours since the snow started falling on Monday, with law enforcement officers and other emergency personnel responding to dozens of crashes and slide-offs due to the icy conditions.
MHP Sergeant Ben Havron says slick conditions played a role in a crash on Interstate 15 just outside of Great Falls on Tuesday morning that could have been much worse.
He says the truck was northbound on the interstate when the vehicle lost traction, causing the driver to over-correct several times.
The driver then lost control and the vehicle rolled several times; no injuries were reported.
Havron says when emergency officials are responding to the scene of a crash, drivers in traffic need to slow down, move into the other lane, and heed officials' instructions for everyone's safety.
"On the two-lane roads, it's very important that you slow way down and move into the other lane if possible and if that's not possible because of oncoming traffic, you have to slow way down as you proceed past us," said Havron.
He says it's also important to plan ahead, so that in the event of a crash drivers are prepared.
"Make sure you have emergency equipment with you in the trunk like blankets, extra coats, gloves, boots and some food, spare food supply and water, just in case something happen where you're stranded somewhere, 'cause we're pretty busy right now and it might take us awhile to get to you so it's a good idea to just be prepared," he added.
Havron says it's important that everyone wear their seat belts, that their vehicle maintenance is up to date, and that their vehicles' tires are ready for winter driving conditions.
