Mountain Grade Prep Checklist

When to use this checklist

Use this before accepting a load that crosses a mountain pass, long downgrade, chain-control zone, or grade advisory segment. The goal is to confirm route approval, equipment condition, weather, load weight, and parking options before the truck is committed to conditions that are harder to reverse once the descent begins.

Route and weight planning

A routing problem on a mountain corridor is more consequential than on a flat stretch — clearances, weight limits, and grade lengths that don't affect most loads can matter significantly here.

• Confirm the route is approved for your equipment, weight, and trailer type using a commercial navigation tool — not a passenger GPS.
• Know the longest and steepest downgrade on the planned route. Loaded weight affects brake cooling very differently than an empty or lightly loaded trailer.
• Review carrier mountain-driving policy before dispatch, not while the truck is already at the top of a grade.
• Check state-specific truck route restrictions, permit requirements, and seasonal closures before departure.

Weather and road conditions

Mountain weather forecasts for a specific grade or pass can differ significantly from the general corridor forecast. These checks are for the crossing itself, not the region around it.

• Check official NWS forecasts and state DOT resources for the specific pass or grade segment before departure — not just the general corridor forecast.
• Look for active chain-control advisories, speed restrictions by vehicle type, and any pass closure history for the current season.
• Identify lower-elevation staging or holding areas in case the pass closes or a weather hold develops after arrival.
• Check whether the forecast window changes during the planned crossing — a pass that is clear at departure time may not be clear at arrival time.

Equipment review before the grade

Brake performance on a long descent depends on adjustment, condition, and load weight — not on the last flat-highway check. Review these before the grade, not at the brake-check area at the top of it.

• Confirm brakes are adjusted and functional for the load weight and grade length — not just adequate for flat highway driving.
• Check tire condition and pressure, and verify that chains or traction devices are required for this route and are aboard in usable condition.
• Know the engine brake (Jake brake) setting and whether the cab configuration supports controlled descent for this load.
• Identify any load-shift risk for the specific cargo type on a steep or winding descent before the trip starts.

Before entering the grade

Each of these applies at the moment the driver still has a real choice. After speed builds on a steep descent, the options narrow to whatever the driver already knew before the top.

• Stop at posted brake check areas before long descents — these exist for load and grade reasons, and skipping them under schedule pressure is a safety decision, not a time decision.
• Know where chain-up areas are located before reaching the restriction point, not after the sign appears.
• Select the correct descent gear before the grade starts, not after speed has already built.
• Know the location of runaway truck ramps on the planned route before the descent begins.

Parking and staging near mountain routes

Mountain routes compress parking and staging choices in ways flat corridors don't. A lower-elevation stop named before the climb is the only real backup if conditions change at the top.

• Name a lower-elevation parking option before the climb — do not assume parking is available on the far side of a grade under uncertain weather or tight timing.
• Chain-up areas, truck inspection pullouts, and rest areas near grades fill quickly during weather events; plan for them to be unavailable.
• Build extra schedule time for slower mountain speeds, mandatory brake checks, chain-up time, and possible weather holds before accepting the load.
• Do not combine the only fuel stop with the only parking option on the far side of a difficult grade under time pressure.

Red flags

These conditions, if found at the grade rather than before it, mean the decision has already been made by default. Each one is easier to address from the terminal than from the top of a pass.

• Chain controls or advisories are active and chains have not been confirmed aboard and usable.
• The schedule requires crossing the grade near the end of the HOS window with no early lower-elevation stop option.
• No lower-elevation backup stop has been named before committing to the pass.
• Equipment, brakes, or tires have a known issue that has not been resolved before departure.
• The weather forecast shows a closing or deteriorating window during the planned crossing time.

Mountain route planning worksheet

Complete this before any trip that crosses a significant grade or pass. A blank field is a planning gap — mark who will verify it and by when.

Plan A / Plan B / Plan C worksheet

Name the backup plan before the truck is committed to the grade. A closure, equipment concern, or weather hold that develops at the summit is too late to plan around.

Decision log

Use this when weather, chain controls, an equipment concern, or a closure changes the mountain plan after departure.

Escalation triggers

• Chain controls are active and the carrier or carrier policy has not confirmed the decision to proceed.
• A brake concern, tire issue, or equipment problem exists before the grade and has not been resolved.
• The only parking option on the plan requires completing the grade after the HOS window has narrowed significantly.
• Weather has worsened since dispatch and no lower-elevation hold plan has been confirmed with dispatch.
