Fuel stops are critical on this route, especially in the vast stretches of Utah. From Monticello, you'll pass through Moab (gas available), then Green River, and Salina. After Salina, the next reliable fuel is in Beaver, roughly 80 miles. Always fill up when you hit half a tank, as stations can be sparse. I-70 west of Green River has limited services, and in summer, temperatures can exceed 100°F, increasing fuel consumption.

• Electric vehicle charging: Superchargers in Moab, Green River, and St. George along I-15. Not many between Monticello and Moab, so charge fully before departing.
• Food and water: Carry at least a gallon per person per day. Restaurants are concentrated in towns; between Moab and Green River, there is only one rest stop with a snack bar.

Road quality is generally excellent on interstates, but US-191 from Monticello to Moab is a two-lane highway with occasional wildlife crossings. Be alert for deer, especially at dawn and dusk.
