The reality is that yes, we can be fined for it. And it is that going at a lower speed than the regulation indicated can also suppose a fine. And it is that, depending on the circumstances, going slower than recommended also means that we put our safety at risk. We know what sanctions can be imposed on us and on what type of road.
There are minimum speeds allowed

As you know, the General Directorate of Traffic (DGT) puts the focus and tirelessly persecutes those drivers who commit speeding offenses that can lead to large fines and can even become a crime.
However, and although they are the most common, it should also be taken into account that we can be fined for going slower than recommended . All this without forgetting other sanctions that are very common, such as not overtaking correctly, among others.
Because it is true that traffic signs take care of reminding us when we enter a new section of our journey. But it is also true that what these signs do not tell us is that there are also minimum speeds allowed. For example: can we go 40 km/h on the motorway or motorway? Well, driving at this speed with cars that are around speeds of 100 and 120 km/h is not the most advisable…
What you should know
Contrary to popular belief that the DGT only pays attention to the fastest drivers , since their mortality rate is higher, as well as being an action that is repeated more frequently, the road agency led by Pere Navarro also pays attention over the slowest . And it is that driving at a speed well below what is possible, generating retentions can also be very dangerous and cause accidents.
Even more so if this step is made in the left or central lane , in case the road has more than two lanes. These sides are always reserved for overtaking or for traffic circumstances that make it advisable, such as a traffic jam or the passage of an emergency vehicle on the right.
The fact that the General Traffic Regulations have also regulated the minimum speed makes perfect sense. For example, a driver who travels at only 30 km/h on a motorway or dual carriageway under normal circumstances, while other vehicles travel at 100 or 120 km/h , is very risky for him and for others who drive. they have to go ahead when they have the possibility.

The fines are 200 euros, but can reach 500
The regulations of the DGT clarify, in this sense, that it is forbidden to “drive a motor vehicle on a motorway or dual carriageway at a speed of less than 60 km/h” because it is considered that this fact may pose a risk to themselves and to the rest of the users because they are exposed to accidents. This would be considered a serious infraction and the fine would be 200 euros , 100 prompt payment and would not result in loss of points.
Similarly, on an urban road whose speed limit is 50 km/h, you cannot go at 25 km/h. “In the rest of the roads, the minimum limit will depend on each vehicle and the maximum speed allowed on that specific road,” the legal text qualifies.
Nor on highways and motorways do not forget how to drive correctly. That is why article 31 of the General Traffic Regulations states that, whenever possible, you must drive in the lane furthest to the right , reserving the lanes on the left side only for overtaking slower vehicles. If this is not fulfilled, the penalty ranges from 200 to 500 euros .
