Dos and don'ts for driving a loaded semi-truck in mountain terrain
Do's
- Perform thorough pre-trip inspections: Check brakes, tires, fluids, cooling system, lights, and ensure all components are in optimal condition.
- Plan your route: Obtain information on steep grades, weather conditions, and consult with experienced drivers or resources like Smart Trucking.
- Maintain proper weight distribution: Ensure the load is evenly distributed across axles to optimize traction and stability. Consult the vehicle's manual or experts for specific guidance.
- Go slow and steady: Descend and ascend mountain roads at a cautious pace. Start descends at a speed below the posted limit, according to Schneider Jobs.
- Use a lower gear: Shift into a lower gear when ascending and descending to maintain control and reduce strain on the brakes and engine.
- Utilize engine braking (Jake Brake or retarder):This is crucial for controlling speed on descents and preventing brake fade. Use it in conjunction with light, controlled service brake applications, says Source Trucking Academy.
- Be aware of road and weather conditions: Pay close attention to potential hazards like ice patches or curves.
- Install tire chains when needed: Chain up at the bottom of the hill when signs indicate snowy or icy conditions.
- Leave ample following distance: This allows for more time and space to react to unexpected situations.
- Use runaway truck ramps if necessary: These ramps are designed as a last resort in case of brake failure or loss of control on steep downgrades.
Don'ts
- Don't rush: Avoid the temptation to speed up or rely on gauging the grade visually.
- Don't overuse the service brakes: This can lead to overheating and brake fade, potentially resulting in complete brake failure.
- Don't tailgate: Maintain a safe distance from other vehicles, especially on grades.
- Don't assume good traction: Be cautious and adjust your driving style in potentially slippery conditions like wet, snowy, or icy roads.
- Don't rely solely on Descent Mode on slippery roads: Descent Mode (if available on your truck's AMT) is not recommended for poor traction conditions.
- Don't get overconfident: Remain vigilant and focused, even on familiar routes.
- Don't ignore signs of overheating: If the engine temperature rises, pull over and allow it to cool down.
