Research Methodology

How we collect, verify, and maintain accurate DUI procedure data across 821 county jurisdictions.

Data Collection Process

DUI.guide maintains a systematic research process developed over 3 years of collecting procedural data from state codes, county court systems, and local government websites. Our team focuses on logistical information—deadlines, fees, court locations, and administrative procedures—rather than legal advice.

Primary Sources

We collect data directly from official government sources, maintaining archived copies when live links become unavailable:

  • State Legal Codes - Penal codes, vehicle codes, and DUI statutes for each state
  • DMV Administrative Rules - License suspension procedures and hearing deadlines
  • County Court Websites - Court addresses, filing procedures, and local requirements
  • Municipal Code Archives - Local ordinances affecting DUI procedures
  • Administrative Orders - Court administrative orders that modify standard procedures

Verification Standards

Each data point goes through our three-stage verification process:

Stage 1: Initial Research

Research analysts review official state codes and county websites to identify relevant procedures, deadlines, and requirements. We document source URLs, section numbers, and effective dates for all information collected.

Stage 2: Cross-Reference Validation

Data is cross-referenced against multiple official sources. For example, DMV hearing deadlines are verified against both state administrative code and DMV handbooks. Court addresses are confirmed through multiple county website pages and phone directory listings.

Stage 3: Quarterly Review

Legal procedures change regularly. Our team conducts quarterly reviews of high-impact data points including filing deadlines, court locations, and fee structures. State law changes are monitored through legislative tracking services.

County-Specific Research

Each of our 821 covered counties receives individual research attention:

  • Court Information - Physical addresses, phone numbers, clerk contact information
  • Local Procedures - Filing requirements that differ from state standards
  • Fee Schedules - Bail ranges, impound fees, administrative costs
  • Processing Times - Typical timeframes for hearings and administrative actions

Update Schedule

Different types of information are updated on different schedules based on how frequently they change:

  • Monthly - Court addresses and contact information
  • Quarterly - Fee schedules and administrative deadlines
  • Semi-annually - State law summaries and penalty ranges
  • As needed - Emergency updates for significant law changes

Research Team

Our research is conducted by legal information specialists with backgrounds in court administration, paralegal services, and legal research:

  • Michael Rodriguez, County Court Specialist - 12 years in county administration, former court clerk
  • Dr. Lisa Park, Legal Information Director - PhD Criminal Justice, 15 years legal information management

Limitations

This guide provides logistical and procedural information only. We do not provide legal advice, case strategy, or attorney recommendations. Local procedures can change without notice, and individual cases may have unique circumstances that affect standard procedures.

For legal strategy specific to your case, consult with a licensed attorney in your jurisdiction.
