Convoy driving – winter mountain passes

Convoy overview

Escorted convoys keep traffic moving when the mountain pass is too hazardous for free driving. Preparation, the right gear and disciplined driving protect everyone in the line.

Before you set off

  • Check alternative routes and closure warnings before leaving home
  • Monitor messages from the Norwegian Road Traffic Centre via Vegvesen trafikk or the service described in The traffic system
  • Pack thermal clothing, food and water; see Emergency equipment in the car
  • Inform your travel party about the expected arrival time and potential delays

When and where convoys form

  • Issued during high winds, snowdrift, icing or extremely poor visibility
  • Signs and roadside staff direct you to the assembly point
  • The lead vehicle organises the queue and starts when the line is ready

Queueing at the meeting point

  • Arrive early, follow staff instructions and signage
  • Heat the cabin, clear the glass and ensure all lights work
  • Join the line calmly; the lead car will start at a steady pace

Convoy order

Driving behaviour in the convoy

  • Keep steady gaps; avoid sudden acceleration or braking to limit snow spray
  • Use dipped headlights; add fog lights only when visibility collapses
  • Never overtake or stop unless directed by the lead car

Vision and communication

  • Follow the lead vehicle’s rear lights and roadside reflectors
  • Use hazard lights only to warn of danger; otherwise keep lighting steady
  • Clear mirrors and windows frequently with the heater or climate control

If you lose contact

  1. Ease off gently; do not brake hard
  2. Make yourself visible with lights while maintaining space for following traffic
  3. Stop only if you must and choose a safe spot; wait for instructions or the next convoy
  4. Call the Road Traffic Centre if you are stranded and need assistance

If the queue stops for a long period in cold weather, air the cabin periodically to avoid condensation and start the engine at intervals to maintain warmth. See Climate control and cabin air quality for more advice.
