Acceleration lane
The sign indicates that an acceleration lane merges into another lane with mutual adjustment in accordance with the provisions of trafikkreglene (merging).
When you see the sign
Adjust your speed and position so that traffic from the acceleration lane can merge into the other lane. Cooperate with the drivers in the other lane, and let the vehicles continue alternately without unnecessary obstruction. Use your turn signal before moving laterally into the lane.
Rules
- Merging must take place through mutual adjustment between the vehicles in the two lanes.
- As far as possible, drivers should continue alternately, meaning one from each lane.
- The driver in the acceleration lane does not have an absolute duty to yield, as in an ordinary lane change; both parties must contribute to the merge.
- The sign does not change the speed limit and never authorises you to exceed it.
Tips
- Use the acceleration lane to reach a speed suitable for the traffic in the lane you are entering.
- Find a suitable gap early, and avoid stopping at the end of the lane if the traffic conditions make it possible to merge safely.
- Keep a sufficient distance from the vehicle in front so that a vehicle from the other lane can merge in.
- Use your turn signal clearly when you are going to move laterally, but always check your mirrors and blind spot before merging.
Common misconceptions
- Believing that the driver in the acceleration lane always has an absolute duty to yield to all traffic in the other lane.
- Believing that the sign means that a motorway or expressway begins.
- Interpreting the term «acceleration» as permission to drive faster than the speed limit.
Test yourself
Easy
What does this sign mean?
- AIt indicates that a separate heavy-traffic lane begins.
- BIt indicates that the driver in the ending lane has full responsibility to give way.
- CIt indicates that two lanes merge through mutual adjustment.
- DIt indicates that the traffic rules for motorveg begin to apply.
Medium
You are driving in the lane that will soon merge with the lane on the left. How should you act?
- AYou adjust your speed and position and cooperate in alternating merging.
- BYou increase your speed above the speed limit to enter first.
- CYou continue without adjusting because traffic on the left has a duty to give way.
- DYou stop at the end of the lane and wait until the road is empty.
Hard
You pass this sign on a road with a signed speed limit of 80 km/t. Which conclusion is correct?
- AThe sign indicates motortrafikkveg, while the speed limit automatically becomes 90 km/t.
- BThe sign permits an increase in speed, while the speed limit may temporarily be exceeded.
- CThe sign indicates motorveg, while the speed limit automatically becomes 110 km/t.
- DThe sign indicates merging, while the speed limit remains 80 km/t.
Theory test tip
Look for whether the incoming line joins another lane. The trap is often to answer that the acceleration lane has an unconditional duty to yield, whereas the correct rule is mutual adjustment and alternate merging.
Did you know
The sign shows a merging situation in which responsibility is mutual. It therefore differs from ordinary lane-change situations, where the person changing lanes normally has a duty to yield.
Frequently asked questions
Who has to yield when the lanes meet?
Neither lane has an unconditional right of way in this situation. Drivers in both lanes must adjust their speed and position so that they can continue alternately.
Do I have to let a vehicle in from the acceleration lane?
You must contribute to mutual adjustment and provide the necessary space for alternate merging. You should therefore adjust your speed or distance when this can be done safely.
Can I exceed the speed limit to enter the traffic?
No, the term «acceleration lane» does not override the speed limit. You must increase your speed within the legal limit and adapt to the traffic.
Should I stop at the end of the lane if there is a lot of traffic?
Normally, you should adjust your speed early and find a gap so that merging can take place without stopping. Nevertheless, you must slow down or stop if necessary to avoid danger.
