Avoid Steep Grades
Routes planned to avoid steep mountain grades that are challenging for RVs.
Overview
RV routing avoids steep mountain grades that can stress your engine, transmission, and brakes. Routes are planned with gentler alternatives when available, giving you a safer and more comfortable drive.
Why it matters
Steep grades are dangerous for heavy vehicles. Overheated brakes, transmission strain, and reduced control on downhill stretches are real risks. Avoiding steep grades protects your rig and your safety.
How it works
The routing engine identifies road segments with steep grades and, when your vehicle profile indicates a heavy or large RV, routes around them when a reasonable alternative exists. You still get to your destination — just on a safer path.
When to use it
- You're driving through mountain passes in the Rockies, Appalachians, or Sierra Nevada
- You're towing a heavy trailer and want to minimize strain on your drivetrain
- You prefer less stressful driving over slightly shorter routes
- You're a newer RV driver building confidence on challenging terrain
