DC Disability Placard Issuance and Regulations

Three distinct disability placard types—one-week permits, temporary, and long-term—are issued by the DC DMV on behalf of the District Department of Transportation. The dataset likely contains issuance records for these permits, which are valid for periods ranging from one week up to eight years. Data feeds were offline for migration as of April 2025, with the most recent data available from December 2024.

Use Cases

• Analyze the distribution and volume of different permit types (one-week, temporary, long-term) based on the described issuance rules.
• Model spatial patterns of disability parking needs based on geospatial placard data.
• Forecast permit renewal cycles and administrative workload based on the eight-year maximum validity period.
• Assess compliance with display regulations (rearview mirror placement) mentioned in the description through potential inspection data.

Strengths

• Explicitly defines three distinct permit categories with clear validity rules (one week, up to 8 years).
• Multiple file formats including CSV and GEOJSON suggest structured and geospatial data availability.
• License is CC-BY-4.0, permitting broad reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data feeds were reported offline for system migration, potentially impacting data freshness.
