A method and arrangement for determining a current location speed-limit in a road-vehicle are disclosed. Described herein is a method of determining a current location speed-limit in a road-vehicle speed-limit information system. One or more signals corresponding to respective candidate speed-limits for the current location are received. A parametrized heuristic algorithm with an associated cost function is applied to decide which candidate speed-limit, if any, that is applicable. If available for the current location, a cloud service supplied estimated true speed-limit and an associated confidence in this estimate is received. An online learning or a reinforcement learning method is used to, based on the cloud service supplied estimated true speed-limit and the associated confidence in that estimate, constantly fit the heuristic's parametrization to, with a high confidence, reproduce the cloud service supplied estimated true speed-limit. A speed-limit information signal correspondingto the decision of the pa
