Emergency corridor in queues
Emergency corridors keep a lane open for ambulances, fire services and police when traffic is congested or stopped. Norwegian regulations require drivers to form a corridor on multi-lane roads whenever traffic halts. Anticipate the need, communicate clearly and position your car so responders pass safely.

When to create a corridor
| Situation | Action | Key detail |
|---|---|---|
| Two lanes in the same direction | Left lane moves left, right lane moves right | Keep the middle gap open; do not block ramps |
| Three or more lanes | Innermost lane moves left, all others go right | Large vehicles only use the shoulder if no other option |
| Narrow city streets | Hug the kerb without blocking pavements | Leave height clearance for ladder trucks |
| Approaching a junction | Stop before the stop line and keep the box clear | Use indicators to show intention |
How to do it
- Spot responders early: check mirrors every few seconds and listen for sirens.
- Alert others: tap brakes or use hazard lights when you are first in queue.
- Position within your lane: left lane to the left edge; others to the right edge.
- Keep wheels straight so the corridor remains predictable.
- Leave extra gap if you drive a long or heavy vehicle.
- Stop completely until the last emergency vehicle has passed.
- Merge smoothly back into normal position once traffic restarts.

Frequent mistakes
| Mistake | Outcome | Fix |
|---|---|---|
| Following the car ahead into the corridor | Blocks the route | Stay tucked to the side even if the gap looks empty |
| Stopping in the middle of the lane | Corridor too narrow | Move decisively to the edge and leave space |
| Filling exit ramps | Prevents alternative routes | Keep ramps clear; hold position in your lane |
| Loud music or phone distraction | Late reaction | Reduce distractions; see Traffic distractions |
Preparation checklist
- Maintain a safety gap you can sacrifice when moving aside.
- Keep mirrors clean and properly adjusted; review Five-see routine .
- Avoid loads or racks that block the corridor, such as wide bike racks.
- Agree with passengers who watches the rear in long queues.
When the queue stops
- Watch mirrors and listen for sirens.
- Shift left or right within your lane according to signage.
- Halt calmly, wheels straight, corridor clear.
- Let all emergency vehicles pass before moving.
- Merge cautiously and restore normal spacing.
