Road Junction with Separate Lane
The sign indicates a road junction with a separate lane.
When You See This Sign
When you see the F20 sign it indicates that a side road has its own separate lane at the junction. Choose the correct lane in good time, signal, and follow the local road signs and markings that indicate yield or right of way.
Rules & Regulations
- F20 is an information sign indicating that a connecting road has a separate lane; the sign does not change the right-of-way rules.
- Always follow the road markings and the yield/stop signs posted at the junction itself; they determine the right of way at the location.
- If you intend to use the separate lane, signal in good time and move into the correct lane early enough.
- Use the separate lane only for its intended maneuver (e.g., exit or deceleration for an entrance); do not park or stop there unless signage specifically allows it.
Tips for Drivers
- Spot the sign early and choose your lane in time to avoid sudden lane changes near the junction.
- Check mirrors and the blind spot for vehicles joining or leaving via the separate lane.
- Signal clearly and in good time before moving into or out of the separate lane.
- Adjust your speed when approaching the junction - short separate lanes often require quicker, more decisive maneuvers.
Common Mistakes
- Assuming F20 gives priority to traffic in the separate lane.
- Assuming the sign forces you to change lanes if you continue straight.
- Underestimating pedestrians and cyclists at the junction by believing the separate lane grants clear passage.

Exam Tip
On the theory test you may be presented with a statement that F20 gives priority or changes the right-of-way rules — the correct answer is that it only shows the layout of the junction; instead follow any yield and stop signs.
Did You Know?
F20 is an information sign in the category of local road markings and is often used where a connecting road has a clearly separated turning or on-ramp lane, for example at entrances to larger country roads or in bigger intersections to reduce conflicts during lane changes.
Frequently Asked Questions
Does F20 change the right-of-way rules at the junction?
No. F20 is an information sign showing that a connection has a separate lane. Any right-of-way obligations are governed by yield or stop signs and road markings at the location.
Do I have to use the separate lane if I'm going to turn?
You should position yourself in the separate lane if it is intended for that turn, and signal in time. If you continue straight you generally do not need to change into a turn lane.
Are you allowed to park in the separate lane shown by F20?
Usually not. The separate lane is part of the carriageway for specific maneuvers and parking is prohibited unless special signage permits it.
Where is F20 most commonly used in Sweden?
F20 is often used at larger intersections and entrances where a side road has its own exit or entrance lane, as well as at certain ramps and major country-road junctions to clarify lane layout.
