About The Mountain Rules Campaign

Colorado’s high elevation and topography can be challenging and require motorists to proceed with extra caution. Truckers have it especially hard in the mountains. When driving a vehicle that’s up to 70 feet long and weighing up to 80,000 pounds, the terrain along the mountain corridor can increase the likelihood of brake failure.

Colorado experiences severe weather events that make driving difficult in the mountains, with high winds and storms that can bring extreme snow and hail. Colorado is also susceptible to hazards such as rockfalls, fires and floods. All of these elements can cause additional challenges and problems for trucks along the I-70 Mountain Corridor

The Colorado Department of Transportation, in partnership with the Colorado State Patrol, Colorado Motor Carriers Association, in-cab driver alert providers, PrePass Safety Alliance and Drivewyze have a shared aim to help enhance safety for truckers traveling through the state’s mountainous areas.

Through this shared aim and resulting coordinated approach, The Mountain Rules was born. This program is a comprehensive, strategic and safety-focused effort to inform and educate in-state and inter-state trucking companies and drivers on the challenges of driving in Colorado’s mountains. It includes information on preventing and avoiding hazards, resources to consider, and a consistent reminder to drive slowly and steadily to be safe for the long haul.  WATCH MOUNTAIN RULES SAFETY VIDEO

Goals & Objectives

In addition to an educational effort, The Mountain Rules consists of infrastructure and informational improvements, including:

      • Signing eastbound Interstate 70 and all eastbound chain stations, east of the Eisenhower/Johnson Tunnels, with information on the brake check locations for truckers.
      • Restriping the wide eastbound exit ramp at the Genesee Park Interchange into a more-defined short-term truck parking area where overheated brakes can cool down and equipment checks can take place prior to the final descent into the Golden area.
      • A new subscription-based, in-cab alert system, warning truck drivers about specific areas where brake failures could occur, and the location of brake check and runaway truck ramps.
