A confidence score (or measure) that is related to the reliability of signal phase and time (SPAT)-compliant messages received at a vehicle. Vehicle-to-everything (V2X)-compliant messages are received from other vehicles and compared to the SPAT-compliant messages. Behavior of vehicles (as indicated in the V2X-compliant messages) in view of the content of the SPAT-compliant messages is evaluated for consistency and a numeric (or other type of) score or measure assigned to the SPAT-compliant message (indicating reliability of the SPAT message). The score is compared to a threshold and based upon the comparison, a determination can be made as to whether to use the SPAT-compliant message to perform an action.
