Abstract: A road module for regulating a passability of vehicles on a roadway. The road module includes an elongated container immersed across the roadway and having an upper plane being essentially at level with the roadway. A lid is pivotally arranged and hinged along an edge of the container. The edge extends along a longitudinal side of the container facing vehicles approaching the road module. The lid forms at least a part of the upper plane of the container. An eccentrically mounted cylindrical roller is configured to support the lid at an opposite longitudinal side of the container. The roller is rotatable between an upper or a lower position. An actuator is configured to rotate the roller to lower and raise the lid, thereby forming a downward ramp in a passing direction of the vehicles when the roller is in the lower position.
