Get clear, practical answers to the most common questions about the D55 - Minimum speed road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Danish driving theory exam in Denmark.
The D55 sign means you must not drive slower than the indicated speed. It's a mandatory instruction to maintain a certain pace, ensuring traffic flows smoothly and preventing slower vehicles from obstructing faster ones, particularly on motorways or designated lanes.
You must ensure your vehicle's speed is at or above the number shown on the sign. Position your vehicle in the appropriate lane indicated by the sign (if applicable) and adjust your speed accordingly. If you cannot maintain the minimum speed due to traffic, weather, or vehicle issues, you may need to pull over safely if possible.
A common trap is confusing the minimum speed sign with a maximum speed limit. Remember, D55 requires you to go *at least* the indicated speed. Another trap is ignoring supplementary panels which might indicate the minimum speed applies only to certain vehicles or during specific times.
The minimum speed requirement typically ends when you see an 'End of Restriction' sign (often a diagonal bar across the sign, or a sign indicating the end of the road type). Always be vigilant for these signs or other traffic rules that may supersede the minimum speed instruction.
If traffic conditions legitimately prevent you from reaching the minimum speed, you should drive as fast as is safe and practical given the circumstances. However, the sign implies that under normal conditions, you should be able to maintain that speed, so be aware of why you are slower and ensure you are not causing an unnecessary hazard.
