Speed Zone & Pacing Audit
Speed Zone & Pacing Analysis
Audit the legal validity of the speed zone and analyze whether the officer's pacing testimony is geometrically consistent with the alleged speed.
Speed Zone Legal Audit
Answer each question based on what you know or can find via public records. Unknown answers identify what to request.
Is the posted speed limit 25 mph (urban), 50 mph (non-urban), or 60 mph (state highway)?
Has the jurisdiction produced an engineering and traffic investigation study establishing this speed limit?
Has the jurisdiction adopted a specific ordinance, resolution, or traffic control order establishing this speed limit?
Does the speed limit sign comply with MUTCD specifications for size (R2-1), color (black on white), retroreflectivity, and mounting height?
Is the speed limit sign clearly visible to a driver approaching from your direction, without obstruction by foliage, structures, or other signs?
Is the speed limit sign placed at the beginning of the speed zone, with advance warning signs where required?
If this is a school zone, was the reduced speed limit in effect at the time of the infraction (school days, during arrival/dismissal hours)?
If this is a work zone, were workers actually present at the time of the infraction?
