Why Mountain Driving Is Different
Mountain roads demand different skills: engine braking, low-gear control, and awareness of altitude effects on your car and your body. Steep descents can overheat brakes; thin air can reduce engine power. With the right technique, passes like the Stelvio, Trollstigen, and Furka are manageable — and spectacular.
Engine Braking and Low Gears
Don’t ride the brakes — On long descents, constant braking heats the pads and fluid. Brakes can fade or fail. Use engine braking instead: select a low gear (second or third) and let the engine hold your speed. Touch the brakes only when you need to slow further.
Choose gear before the descent — Shift down at the top of the pass, not halfway down when you’re already going too fast. In a manual transmission, match revs when downshifting to avoid jerking.
Automatics — Use manual mode or L/2 if available. If not, shift to a lower range before descending.
Hairpin Bends and Narrow Roads
Slow before the bend — Enter hairpins at a speed you can maintain through the turn. Braking mid-bend can cause understeer or loss of traction.
Use the full width — On single-lane sections, use pullouts to let faster traffic pass. Don’t block the road.
Honk on blind corners — In the Alps and other mountain regions, a short honk before a blind curve warns oncoming traffic. It’s customary and appreciated.
Passing Etiquette on Narrow Roads
Uphill has priority — In many European mountain areas, vehicles climbing have the right of way. It’s harder to restart on a slope. Pull into a turnout to let uphill traffic pass.
Use pullouts — Designated passing bays are there for a reason. Don’t force a pass on a narrow section.
Buses and trucks — They need more space. Give way and wait for a safe spot.
Altitude Effects on Your Car
Reduced power — At 2,000m+ altitude, engines lose 20–30% of power. Overtaking and climbing will feel sluggish. Plan for slower progress.
Coolant and fluids — Check levels before a long climb. Thin air affects cooling efficiency.
Fuel — Some high-altitude stations have lower octane. If your car requires premium, plan fuel stops accordingly.
Famous Passes: What to Expect
Stelvio Pass (Italy) — 48 hairpins, 2,757m. Open roughly June–October. Very busy in summer. Go early to avoid crowds.
Trollstigen (Norway) — 11 hairpins, dramatic views. Often closed in winter. Narrow; large vehicles may struggle.
Furka Pass (Switzerland) — High altitude, stunning scenery. Check vignette requirements for Swiss highways when planning access.
Many passes close in winter. Check status before you go.
Winter: Chains and Snow
Chain requirements — In the Alps and other mountain regions, snow chains are mandatory when signs indicate. Fines for non-compliance are steep. Rental cars may include chains — confirm at pickup.
All-season vs winter tires — In winter, winter tires are often required. All-season tires may not satisfy legal requirements on mountain roads.
Know your limits — If conditions are bad, consider postponing or taking a train through the pass. No view is worth the risk.
