This document describes techniques and systems to indirectly verify speed limits based on contextual information for autonomous and semi-autonomous driving systems. In addition to camera systems, the described techniques and systems use other sensors and secondary factors to improve the accuracy and confidence in detecting posted speed limits. For example, a camera system captures an image or other data directly indicative of a speed limit. Contextual information for the road or vehicles nearby is also obtained and used to determine at least one indirect indication of the speed limit. A composite speed limit is identified by applying a respective weight to the direct and indirect indications of the speed limit. The described systems and techniques thereby enable controlling the vehicle based on the composite speed limit. In this way, the described systems and techniques can verify a speed limit to make autonomous and semi-autonomous driving systems safer.
