The Route: California to Colorado

This route guide outlines a common and efficient path for commercial truck drivers traveling from California to Colorado. The specific origin and destination within each state will influence exact mileage and travel time, but this guide covers the major Interstate routes and key considerations.

The primary route utilizes I-15 North to I-70 East. Starting in Southern California (e.g., Los Angeles area), drivers will take I-15 North through the Mojave Desert, passing through Nevada. The route continues through Utah, where I-15 merges with I-70 East near Cove Fort. From there, drivers remain on I-70 East, entering Colorado and continuing towards major cities like Denver.

An alternative, slightly longer, route from Northern California uses I-80 East to I-70 East. Beginning near Sacramento, drivers would take I-80 East through Reno, Nevada, and then continue through Utah. Just east of Salt Lake City, drivers would transition south onto I-70 East to continue into Colorado. This route avoids some of the heavier traffic on I-15, but is generally more mileage.

Compliance & Permits

Drivers must ensure full compliance with all federal and state regulations along the route. Be vigilant regarding hours-of-service regulations, proper load securement, and vehicle maintenance.

Expect to encounter weigh stations along both I-15 and I-70. Specific locations include, but are not limited to:

• California: Multiple weigh stations exist along I-15 as you exit the state. Be prepared for inspections related to vehicle safety and emissions compliance.
• Nevada: Be prepared to stop at the agricultural inspection station as you leave California. Expect weigh stations along I-15.
• Utah: Port of Entry and Weigh Station locations exist on both I-15 and I-70. Remain compliant.
• Colorado: Several weigh stations exist along I-70 as you enter and travel through the state.

Regarding permits, remember that requirements can vary based on your vehicle's weight and cargo. Colorado requires permits for overweight or oversized loads. Consult the Colorado Department of Transportation (CDOT) website for detailed information and necessary permit applications. For vehicles traversing the state of Utah, be mindful of their specific regulations regarding weight and dimensions.

Risks & Hazards

This route presents various seasonal weather risks that drivers must be prepared for.

• Summer: Expect extreme heat in the Mojave Desert along I-15. Maintain proper tire pressure, monitor engine temperature, and stay hydrated. Wildfires can also create reduced visibility and temporary road closures.
• Winter: The mountain passes along I-70 in Utah and Colorado can experience heavy snowfall and ice. Chain laws are frequently enacted, and drivers must carry and be proficient in installing tire chains. Road closures due to severe weather are possible. Check weather forecasts and road conditions before and during the trip.
• Spring/Fall: Unpredictable weather patterns can occur in the mountains, including sudden snowstorms, high winds, and flash floods. Be prepared for changing conditions and adjust your driving accordingly. Strong crosswinds are common in open areas along I-80 and I-70.
