In the clip, you hear what speed NTF Värmland's operations manager Anders Kalborg thinks would be suitable for the A-tractors
Two years ago, new rules were introduced that make it easier to convert a car into an A-tractor.
Since then, the number of A-tractors that roll on the roads has increased significantly.
In the autumn, the government commissioned the Swedish Transport Agency to investigate tightening in several areas to improve traffic safety.
NTF is one of the organizations that presented its views.
- We want a completely new education for A-tractor driving licenses, and an increase in the maximum speed, says Anders Kalborg, operations manager for NTF Värmland.
