Fuel and Route Economics
Gas prices increase as you leave California; fill up in Barstow or Baker for cheaper rates. The Mojave stretch has long gaps between stations—especially between Baker and Las Vegas. A full tank from San Diego should get you past Las Vegas. Average cost for the trip: approximately $80–100 (mid-grade, 25 mpg).

• Fuel up at major towns: San Diego, Temecula, Barstow, Baker, Las Vegas, St. George
• Desert sections: carry extra water and emergency supplies
• EV charging: available along I-15 at rest stops and in Las Vegas

Infrastructure Safety and Road Quality
Interstate 15 is well-maintained, with the exception of occasional construction near the Nevada border. US-89 from Mount Carmel Junction to Kanab is a scenic two-lane road with good pavement but sharp curves. Speed limits: 65–70 mph on interstate, 55–65 on US-89. Cellular coverage: spotty in remote areas; download maps offline.

Fatigue Management and Rest Zones
Long desert stretches can cause highway hypnosis. Plan stops every 2 hours. Key rest areas: the Baker Rest Area (Cronese Moave), the Valley of Fire Rest Area (Nevada), and the newly renovated St. George Rest Area. In Kanab, the public park near the visitor center is a great place to stretch.
