The San Bernardino Mountains: A Natural Beauty With Risks

  • Unique Terrain Features

The San Bernardino Mountains are in Southern California. They are in the Transverse Ranges, which are known for their rough terrain and wide range of ecosystems. As you go up these hills, you will face steep grades, tight turns, and changing weather, which can be very difficult for drivers.

  • Weather Variability

The rapidly changing weather is one of the most unpredictable aspects of mountain driving in the San Bernardino area. While you may start your journey under clear skies, thick fog, rain, or even snowfall can quickly become a reality as you ascend elevation. Being prepared for these sudden weather changes is crucial.

Vehicle Preparation: Your First Line Of Defense

  • Tires And Brakes

Before embarking on your mountain adventure, ensure your vehicle’s tires are in good condition and have adequate tread depth. Additionally, check your brakes to ensure they are in optimal working order, as descending steep mountain grades can stress them significantly.

  • Engine And Fluids

Regular maintenance checks on your vehicle’s engine, transmission, and fluid levels are essential. Overheating can be a concern when ascending steep grades, so ensure your cooling system is in top shape.

  • Suspension And Steering

A well-maintained suspension and steering system are vital for navigating the twists and turns of mountain roads. Ensure that your shocks, struts, and steering components are in good condition to maintain control and stability.

  • Adequate Fuel And Supplies

Mountain roads can be remote, with limited gas stations and service access. It’s wise to start your journey with a full gas tank and carry emergency supplies, including water, non-perishable food, and a first-aid kit.

The Art Of Mountain Driving

  • Gear Down For Climbs

When ascending steep grades, shift your vehicle into a lower gear. This allows your engine to work more efficiently, reducing the risk of overheating and providing better control.

  • Brake Management On Descents

Descending steep mountain grades can be a nerve-wracking experience. Avoid riding your brakes constantly, which can lead to brake fade and loss of stopping power. Instead, use engine braking by downshifting to a lower gear and gently applying the brakes when necessary.

  • Slow And Steady

Mountain roads are not the place for speed demons. Slow down, especially on tight curves, to maintain control and reduce the risk of accidents. Remember that you’re sharing the road with other drivers, cyclists, and pedestrians.

  • Watch For Wildlife

The San Bernardino Mountains are teeming with wildlife. Be vigilant, especially during dawn and dusk, and watch for deer, bears, and other animals that may dart across the road unexpectedly.

Safety Precautions For Mountain Driving

  • Seatbelts And Child Safety

Always make sure that child safety seats and seatbelts are properly fixed and that all people are adequately restrained. These safety steps can assist greatly in the event of an accident or quick stop.

  • Cell Phone Use

Distracted driving is always dangerous, but it’s even more dangerous on hilly roads. Keep your eyes on the road ahead and ask a partner to help you with directions or calls.

  • Emergency Kit

In addition to the previously mentioned supplies, your emergency kit should include flares, a flashlight with extra batteries, and a blanket. These items can be invaluable in an unexpected breakdown or inclement weather.

  • Inform Others

Tell someone about your trip plans, including where you want to go and when you think you’ll get there. If you run into trouble, someone will know where you are and can call the police if they need to.

Weather Challenges In The San Bernardino Mountains

  • Winter Driving

Heavy snowfall and icy conditions can happen in the San Bernardino Mountains in the winter. Install snow chains on your car, bring a shovel, and check the road conditions before you leave. Think about canceling your trip if the weather is bad.

  • Fog And Rain

Thick fog and rain can reduce visibility drastically. Use low-beam headlights and fog lights if equipped. Drive cautiously, reduce your speed, and maintain a safe following distance from other vehicles.

Road Etiquette: Sharing The Mountain Roads

  • Yield To Larger Vehicles

Larger vehicles like trucks and buses may struggle more on steep grades and tight curves. Yield the right-of-way when safe and practical to do so.

  • Pull Over Safely

If you’re driving slower than the flow of traffic and turnouts or pull-off areas are available, use them to allow faster-moving vehicles to pass safely.


Mountain driving in the San Bernardino area is a rewarding experience, offering a chance to connect with nature and take in breathtaking scenery. However, it also demands a high level of preparation, caution, and respect for its unique challenges.
