Final answer:
The complaint should include the posted speed limit as well as the actual speed limit based on radar.
Step-by-step explanation:
The missing word in the given sentence is the actual speed limit that the person was going (based on radar). The complaint should include the posted (Prima Facie) speed limit, which is the legal speed limit indicated by the signage. In addition to that, the police officer should annotate the actual speed limit that the person was going, which is determined using radar.
