Mountain Driving: A Comprehensive Guide

Mountain regions often have large animal populations, so animal strikes are a real risk, especially in shaded valleys and on blind curves.[web:443][web:446] Larger animals such as elk and bears can cause severe damage and injuries if hit.

Reduce your speed, scan ahead, and avoid driving at night when visibility is low and animals are more active.[web:446][web:455] Stay alert even in daylight and be ready to slow or stop in areas with wildlife warning signs.

Weather can change rapidly with elevation, turning clear skies at the base into fog, rain, or snow at higher altitudes.[web:444][web:446] Check forecasts for the entire route, including passes and summits, before you start driving.

Be prepared for sudden changes by carrying appropriate clothing, allowing extra time, and being ready to delay or reroute your trip if conditions deteriorate.[web:445][web:451]

Steep grades and long climbs place extra stress on your engine, brakes, and transmission.[web:448][web:451] Any existing mechanical issues are more likely to cause trouble in mountainous terrain.

Before your trip, check brakes, tires, fluids, lights, and wipers, and address any warning lights or unusual noises. Breaking down on a narrow mountain road can be expensive and unsafe.

On many mountain passes, snow can accumulate by the foot in just a few hours, even when lower elevations are clear.[web:444][web:451] Chains provide vital traction on steep, snowy grades and may be legally required in some areas.

Carry the correct size chains and know how to install them before you need them. Having chains ready can prevent you from getting stuck and blocking traffic.

In remote mountain areas, gas stations may be far apart and more expensive, and some may close early or seasonally.[web:444][web:451] Running low on fuel can leave you stranded with limited options.

Refuel before entering long stretches of mountainous terrain and keep your tank at least half full, especially in winter when you may need to idle for heat if traffic stops.

Sharp curves are common on mountain roads, and downhill grades increase your momentum.[web:443][web:451] Slow to a safe speed before the curve, then maintain or gently accelerate through it for better stability.[web:448]

Braking hard while in the turn can shift weight forward and reduce traction, making it easier to lose control. Look ahead, choose a safe entry speed, and commit to smooth steering.

Begin slowing and select a lower gear before you start down a long grade.[web:445][web:451] Using engine braking helps control speed without overheating your service brakes.[web:447][web:453]

Whether you drive a manual or an automatic with lower gear options, choose a gear that lets you descend at a steady, manageable speed with minimal brake use.

Instead of riding the brakes continuously, apply firm, steady pressure to reduce speed a few miles per hour, then release to let them cool.[web:447][web:453] This pulsing or “snub” braking helps prevent brake fade on long descents.

If you notice a burning smell or a soft pedal, pull over at a safe turnout and let your brakes cool before continuing downhill.[web:444][web:453]

As you gain or lose elevation, temperatures, wind, and visibility can shift quickly, including sudden fog, rain, or snow.[web:444][web:446] Valleys and passes can go from clear to very limited visibility in moments.

Use headlights in low visibility, reduce speed, and increase following distance. Be prepared to slow significantly or stop if conditions become unsafe.

Crashes, weather closures, or mechanical issues can leave you stopped for hours in remote areas, sometimes without cell service.[web:444][web:451] Having extra food, water, warm clothing, and basic tools can make an unexpected delay much safer and more comfortable.

Keep a small emergency kit in your vehicle with blankets, a flashlight, first aid supplies, and any medications you may need.

In remote mountain regions, cell coverage can be unreliable or nonexistent. A mobile CB radio with an external antenna can still work as long as other CB users are nearby.[web:449]

Many truck drivers monitor channel 19, which serves as an informal highway information channel for hazards, road conditions, and emergencies.[web:449] If you frequently drive in remote mountains, a CB can be a valuable backup communication tool.
