Speed Limit
The sign indicates a prohibition against driving a vehicle at a speed higher than that specified on the sign.
When You See This Sign
When you see the speed sign you should immediately ensure that your speed does not exceed the indicated number. Adjust your braking in good time and maintain that speed until you see a sign that changes or cancels the restriction.
Rules & Regulations
- The sign prohibits operating a vehicle at a higher speed than the number shown; the speed limit must not be exceeded.
- The sign's restriction applies from the point where the sign is placed and continues to apply until it is revoked or a new speed sign indicates a different speed.
- If there is a supplementary plate under the speed sign indicating vehicle types or times, the restriction applies only according to that information.
- The speed limit applies to all lanes and to the vehicles covered by the sign; it is not a recommendation but a prohibition.
Tips for Drivers
- Reduce your speed well before the sign so that you pass the sign at no more than the stated speed; brake smoothly and with planning.
- Use the speedometer or cruise control to maintain the exact speed while the restriction applies.
- Read any supplementary plates directly under the speed sign — they may indicate that the restriction applies only to specific vehicles or times.
- Be extra attentive at roadworks, town boundaries and motorway entrances where new speed limits are often introduced temporarily or permanently.
Common Mistakes
- Believing that the sign is a recommendation rather than a prohibition and that you can therefore drive a little faster.
- Assuming the speed limit automatically ends at the next intersection; it applies until it is explicitly revoked or replaced.
- Not noticing or understanding the meaning of a supplementary plate that limits the speed to certain vehicles or times.

Road Sign: Speed Limit
What does this sign indicate?
- A The maximum permitted speed is indicated — you must not exceed the specified speed.
- B The minimum permitted speed is indicated — you must not drive slower than specified.
- C A recommended speed is indicated, but it is not binding.
- D A temporary speed limit ends immediately.
Exam Tip
On the theory test you may be tested on distinguishing between a speed limit sign and a recommendation sign — remember that C31 is a prohibition. Pay special attention to questions that mention supplementary plates; many incorrect options assume that supplementary plates do not affect who the restriction applies to.
Did You Know?
The speed limit sign with a red ring and black number follows international standards and is used throughout Europe. In Sweden, speed limits are set by the Swedish Transport Administration and the signs are common at transitions between rural roads and built-up areas as well as in temporary roadworks.
Frequently Asked Questions
Does the speed limit apply immediately at the sign?
Yes. The speed limit applies from the point where the sign is placed and onward, so you must have reduced to no more than the stated speed at and after the sign.
Does the sign apply to all vehicles?
As a general rule the sign applies to all vehicles using the road. However, if there is a supplementary plate below the sign the restriction may be limited to certain vehicles or times.
How does a speed limit end?
A speed limit only ends when it is replaced by a new speed sign or by a sign that explicitly revokes the restriction. It does not end automatically at intersections or changes of road unless a new indication is given.
Is there any legal margin above the speed limit?
Formally there is no legal tolerance above the stated speed — driving faster is an offense. Police and measuring devices may, however, account for measurement uncertainty in practice, but this should not be used as a reason to exceed the limit.
