As the first major winter weather incident of the season, it’s a stark reminder of just how quickly the elements can turn Montana's highways into potential disaster zones.

With snow-slicked roads and ice underfoot, the crash sends a clear warning: winter driving here is nothing to take lightly. Here’s everything we know about the accident, why winter driving in Montana is more dangerous than ever, and essential tips to keep yourself safe.

Homestake Pass: A Dangerous Winter Slip-N-Slide

As temperatures plummeted this morning, the treacherous conditions on the I-90 at Homestake Pass—an area infamous for winter incidents—came to life once again.

According to eyewitness reports, the truck appeared to lose control on the icy roads, ultimately jackknifing across both lanes and causing a total standstill. Eastbound travelers found themselves trapped for hours as authorities worked to clear the site and prevent further accidents.

Unfortunately for those traveling Eastbound towards Whitehall, traffic was at a standstill, though vehicles were permitted to cross and turn around every couple of minutes. However, some drivers are still stuck on the road, with many hours to go.

Homestake Pass, one of the highest points on I-90, has long been a hot spot for winter accidents, and today’s incident is just one in a long list of crash statistics.

Last year alone, Montana reported over 2,000 winter-related road accidents, with Homestake Pass claiming a significant share of those. Icy surfaces, sudden snow squalls, and unpredictable wind gusts make it especially dangerous for larger vehicles like semi-trucks, which are more prone to jackknifing in poor conditions.

Stay Safe on I-90 This Winter: Tips for All Drivers

Today’s crash serves as a harrowing reminder of the importance of safe winter driving practices, not just for truckers but for everyone on the road. The Montana Department of Transportation (MDT) suggests these strategies to stay safe on icy highways:

1. Slow Down and Maintain a Safe Distance

Stopping on icy roads takes up to ten times the distance of dry pavement. Lowering your speed and leaving ample space between you and other vehicles can be lifesaving in dangerous conditions.

2. Check Your Tires and Vehicle Condition

Winter tires are not just a recommendation but a necessity on Montana roads during winter. Good tread and proper inflation are essential for maintaining traction. Similarly, make sure your brakes, battery, and windshield wipers are in top condition.

3. Drive with Caution Around Large Vehicles

Give semi-trucks, buses, and other large vehicles extra space, as they need more room to stop and maneuver in the snow. The MDT reports that 15% of winter-related crashes in Montana involve larger vehicles.

4. Stay Updated on Road Conditions

Before hitting the highway, check MDT’s road conditions map or the weather forecast to avoid surprise ice patches, snowfalls, or black ice on routes like Homestake Pass.

5. Carry An Emergency Kit in Your Car

You never know when you may be stuck in traffic for multiple hours—sometimes even up to a day—waiting for traffic to clear. Prepare a kit that includes a blanket, warm clothes, food, water, and whatever else necessary to ensure your survival in the event of a longterm blockage.

A Sobering Start to Winter Driving Season

Today’s I-90 incident is a reminder of the dangers lurking on Montana’s winter roads.

As we head further into the winter season, staying vigilant, planning ahead, and practicing safe driving can help prevent tragedies like the one seen this morning on Homestake Pass.

Whether you’re a daily commuter or an occasional traveler, winter in Montana calls for respect for the road and caution at every turn. The highways are unpredictable and, as today showed, can become life-threatening in an instant. Stay safe out there, Montana.
