Smarter Roadside Sobriety Testing — From Stop to Courtroom with Less Paperwork

standardfield.co

The Challenge

Impaired driving is your officers’ most paperwork-heavy arrest. The Standard Field Sobriety Test — HGN, Walk-and-Turn, One-Leg Stand — must be documented perfectly to withstand court scrutiny. Handwritten notes, missed steps, and memory gaps give defense counsel room to challenge the evidence, leaving convictions on the table. Drug-impaired cases compound the problem further, taking twice as long to prosecute.

How Evidex Works

  1. Guided roadside testing

    Officer opens the app and follows a step-by-step workflow for HGN, Walk-and-Turn, and One-Leg Stand. Every entry is timestamped and GPS-tagged automatically.

  2. Automated report generation

    Evidex pre-populates the complete occurrence report. Officers review and finalize — no station return trip needed to write notes from memory or from paper notes.

  3. Court-ready evidence package

    A sealed, read-only file — timestamped, GPS-tagged, and tamper-evident — is generated that can be directly transferred to records management (RMS) or packaged for handoff to be prosecuted. No retyping, no lost notes.

  4. DRE support when drug impairment is suspected

    If the officer brings the subject in for a Drug Recognition Expert evaluation, Evidex extends the same structured documentation through the follow-up process — maintaining a continuous chain of custody.

Leadership Oversight

  • Real-time dashboard showing test volumes, officer activity, and file completeness
  • Spot training gaps before they become courtroom problems
  • Audit log — every action recorded, nothing deleted or overwritten
  • Geographic data showing impaired driving hotspots across your jurisdiction
  • Supervisor approval workflow before files reach prosecution

What Changes for Your Officers

  • 45–85 minutes saved per stop

    Paperwork that used to take an hour at the station is completed at the roadside and done before they leave the scene.

  • Any officer can run a proper FST

    The guided workflow keeps officers accurate regardless of how recently they have done a test, reducing skill atrophy between incidents.

  • Evidence that holds up in court

    Standardised, complete documentation with no memory gaps. Reduces exploitable omissions that lead to case dismissals or acquittals.

  • Works offline at the roadside

    Data is captured locally and synced securely when connectivity is restored. No dropped reports due to spotty coverage on rural stops.
