End of Road Work Zone
The sign indicates the end of a road section with road work marked by sign A20.
When You See This Sign
When you see A21 it means that the roadworks section marked with A20 has ended. Continue driving with normal attention but still adjust speed and distance until you are sure that all temporary rules and changes to the road surface are gone.
Rules & Regulations
- The A21 sign indicates that the road section previously marked with A20 (roadworks) has now ended.
- A21 is a warning sign; it provides information — it is not in itself a regulation that changes traffic rules.
- Temporary traffic regulations (e.g., reduced speed limits or overtaking bans) that were put in place with regulatory signs only cease when they are explicitly revoked or when the corresponding cancellation sign is displayed.
- After A21 the driver should return to normal vigilance but still adjust speed and driving style to road and visibility conditions until the road has been fully restored.
Tips for Drivers
- Do not increase your speed immediately just because you have passed A21 — check for any remaining temporary speed limits or other regulatory signs.
- Be extra alert to the condition of the road surface and any remaining work, machinery, or materials near the roadside even after the sign.
- Follow road markings and other signs carefully; if a temporary speed restriction applies it must be revoked with a specific sign before you may return to the normal speed.
- Give space to vehicles that are rejoining after the work area and keep a safe distance until the traffic situation feels normal.
Common Mistakes
- Believing that A21 automatically cancels all temporary traffic regulations put in place in connection with the roadworks.
- Interpreting the sign as a prompt to immediately accelerate to the maximum permitted speed without checking remaining speed signs.
- Confusing A21 (end of roadworks section) with the start of a new work area or with a cancellation sign for temporary regulations.

Exam Tip
In the theory test they may try to make you believe that A21 cancels temporary speed limits; the correct answer is that the warning sign only shows that the roadworks section has ended and that regulatory restrictions are only revoked by their own cancellation signs or when the signage indicates it.
Did You Know?
A21 uses the same diagonal stripe as other 'end of' warning signs in the Swedish road sign system and only indicates the end of a warning zone — not the revocation of separate regulations.
Frequently Asked Questions
Does A21 mean that all temporary speed limits have ended?
No. A21 marks the end of the road section that was marked as roadworks, but temporary speed limits (enforced by permanent or temporary regulatory signs) remain in effect until they are explicitly revoked.
Do I need to be extra careful even after passing A21?
Yes. Some work vehicles, materials, or uneven road surfaces may remain beyond the sign, so adjust your speed and keep distance until the road is restored and it is safe to return to normal driving.
What is the difference between A20 and A21?
A20 indicates the start of a roadworks section and warns that you are approaching the work area. A21 indicates that the marked roadworks section has ended. They function as the start and end markers for the same warning zone.
