The M23 sign is a crucial marking used alongside 'No Stopping' (M21) or 'No Parking' (M22) signs to strongly emphasize that stopping or parking is prohibited in that specific area. Its purpose is to reinforce existing regulations, especially where violations are common or safety is critical. Drivers should always treat this marking as a clear and firm indication of a restriction that must be adhered to, ensuring traffic flow and safety.
The M23 road marking serves as a crucial visual aid, reinforcing areas where no stopping or parking rules are already in effect, ensuring drivers clearly recognize restrictions. Correct sign interpretation is vital for avoiding penalties and is a key component of your Swedish theory test revision, demonstrating your knowledge of vital traffic rules.
This marking is used to reinforce curbside restrictions shown by the no stopping and parking marking (M21) and the no parking marking (M22). It emphasizes that the restriction applies clearly along the section and should not be ignored. It is especially helpful where frequent violations occur or where the restriction is safety critical. Drivers should interpret it as an added clarity measure, not as a different type of rule.

Get clear, practical answers to the most common questions about the M23 - Combined Reinforcement for No Stopping/Parking or No Parking road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations.

The M23 sign is a reinforcing marking. It's used with either the M21 (No Stopping) or M22 (No Parking) sign to make the restriction absolutely clear. It signifies that stopping or parking is forbidden in that exact location.
When you see the M23 sign, any action that violates the reinforced 'no stopping' or 'no parking' rule is prohibited. This includes stopping, parking, or even briefly waiting in a way that obstructs traffic or visibility, in the area marked by M21 or M22.
You must treat the restriction as being strictly enforced. If the sign is reinforcing 'no stopping', do not stop at all unless absolutely necessary for traffic reasons. If it's reinforcing 'no parking', do not park your vehicle there. Find a permitted area to stop or park elsewhere.
A common trap is assuming that the reinforcing mark M23 means the rule is optional or less strict. Learners might also get confused if they only see the M23 without recalling the M21 or M22 it's paired with. Always remember M23 is a confirmation of an existing prohibition, not a new rule.
The M23 is typically used in areas where drivers frequently ignore 'no stopping' or 'no parking' rules, or where such stopping would be particularly dangerous. It serves as an extra visual cue to prevent violations and ensure safety, for example, near junctions, pedestrian crossings, or on narrow roads.

This warning sign indicates a danger ahead that cannot be adequately described by any other standard warning sign. It serves as a general alert to increase your vigilance and prepare to adjust your driving. The specific hazard is often clarified with an additional plate or nearby information, and it may be temporary or location-specific. Reduce speed, scan the road environment carefully, and be prepared for unexpected conditions such as unusual road layouts, temporary hazards, or local risks. Treat this sign as a prompt to drive defensively until the hazard is clearly passed.
A red cross displayed above or near a lane means that the lane is closed and must not be used by traffic. In some situations, the closure also applies to the road shoulder next to that lane, meaning you must not drive or continue on that shoulder either. This signal is commonly used for lane control on motorways or multi-lane roads to manage incidents, roadworks, or traffic flow. When you see a red cross over your lane, you must change lanes safely as soon as possible and continue only in an open lane.
