Road Safety, Family Stops, and Fatigue Management
For families, the route offers several kid-friendly stops: the Glen Miller Butterfly House in Spokane, the Silverwood Theme Park in Athol, ID, and the Montana Herbal Center in St. Regis. These provide opportunities to stretch legs and engage children.
Pet-friendly infrastructure includes numerous rest areas with dog runs, but note that some national forest trails require leashes. Always carry water for pets, especially in arid stretches.
Fatigue management is critical on long drives. Plan stops every 2 hours; recommended rest zones include Coeur d'Alene (at Q'emiln Park) and Butte (at the Freeway Rest Area). Well-lit and safe truck stops like Little America in Wyoming are not on route, but many Pilot/Flying J centers in Montana offer secure parking.
For safety, winter driving demands extra caution: carry a winter emergency kit, and be aware of wildlife crossings, especially deer and elk.
If you seek hidden off-route spots, consider the Pintler Scenic Byway (MT-1) near Anaconda, which offers hot springs. Or, just 35 miles north of I-90, the town of Philipsburg offers a historic brewery and sapphire mining.

Fuel costs may be lower in Montana due to lower state gas taxes, but plan ahead as services can be sparse between Spokane, WA and Missoula, MT. Major fuel stops include Spokane, Coeur d'Alene, ID, and Missoula. Diesel and gasoline are generally available at all exits along I-90.
