Challenging 392.2-SLLS2 through FMCSA DataQs

If this violation was written incorrectly, here are the angles trucking-safety managers use to contest it. Playbook: Unsafe Driving.

Relevant 49 CFR49 CFR § 392.2

Applicable operating rules

Every commercial motor vehicle must be operated in accordance with the laws, ordinances, and regulations of the jurisdiction in which it is being operated. However, if a regulation of the Federal Motor Carrier Safety Administration imposes a higher standard of care than that law, ordinance, or regulation, the FMCSA regulation must be complied with.

Common ways to challenge this code

  • Radar / lidar / scale calibration not produced

    The state instrument used to measure speed or weight had no current calibration certificate, or one was never provided when requested.

    Evidence that wins

    • FOIA / public-records request response from the citing agency
    • Calibration log expiration date if produced
    • Driver's contemporaneous note (e.g., independent dashcam speed)
  • Citation based on visual estimate only

    The inspection report indicates the officer estimated speed visually rather than using a calibrated instrument.

    Evidence that wins

    • Inspection report narrative copy showing "visual estimate" wording
    • Officer training records or pacing distance, if obtainable
  • Underlying citation adjudicated

    The underlying state court adjudicated the citation as dismissed, reduced, or amended.

    Evidence that wins

    • Certified court disposition with case number and date
    • Original citation copy

Common pitfalls — avoid these

  • Submitting an uncertified court printout — DataQs requires the clerk-stamped version
  • Forgetting that "guilty of a lesser charge" still counts as conviction — the violation may stay, just at reduced severity
