Every State DOT Requires the Same Thing

Across all 50 state DOTs, traffic-control documentation is required of contractors and utility operators working in public rights-of-way. Each state names the deliverable differently — Caltrans calls it Form CEM-2210, PennDOT calls it CS-901, WSDOT calls it the daily traffic control diary, ALDOT calls it Form C-25 — but the requirement, structure, and field-level evidence are equivalent: a date-stamped, contemporaneous record of traffic-control activity, devices, personnel, deficiencies, and corrections.

DTCD generates the right output for your state automatically. Each per-state page below cites the specific form / spec / construction-manual section that DTCD's output satisfies, with a primary source link to the state DOT's published guidance.
