Nearly every state DOT requires some form of daily traffic-control record. The names — and how strongly each is spec-bound — differ: diary, daily inspection report, work-zone checklist, device record, project diary, logbook, daily work report. The underlying need is the same, and DTCD generates the right output for your state.
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.

DTCD's role across the rule is to document, monitor, and publish — it produces the evidentiary record each provision leans on. It doesn't place devices, supply barriers or attenuators, train workers, or make the compliance determination; those stay with the contractor and agency.
| What the rule calls for | Cite | How DTCD supports it |
|---|---|---|
| Subpart J — Work Zone Safety & Mobility | ||
| Work-zone impact monitoring | §630.1008, .1014 | Produces the contemporaneous, GPS- and time-stamped daily diary and day/night inspection log that is the monitoring record. |
| Trained personnel, on record | §630.1008 | Captures each crew member's traffic-control certification (TCS / flagger), tracks renewal dates, and ties the certified worker to the closure they worked — the trained-personnel record the rule asks for, and the roster that stands behind the workers-present signal DTCD publishes to its CWZ feed. |
| Biennial process review | §630.1008 | Every closure is retrievable on demand behind a tamper-evident audit trail, so a reviewer can pull a project's full history without a paper chase. |
| TMP — Temporary Traffic Control | §630.1012 | Documents the devices actually deployed against the plan and MUTCD typical application. |
| TMP — Public InformationOnly DTCD | §630.1012 | Turns the same field capture into a live, published WZDx / CWZ feed on the USDOT registry that 511 systems, mapping partners, and navigation apps source from — the work zone reaches the map in real time, automatically. |
| Subpart K — Temporary Traffic Control Devices | ||
| Device condition & placement | §630.1108, .1110 | Per-device photo capture; on-device AI flags missing, damaged, or misplaced signs and channelizing devices. |
| Positive protection deployed | §630.1108 | Documents that barrier, crash cushion, or attenuator was in place, and flags when positive protection appears absent for exposed workers. DTCD records and monitors; it does not supply the hardware. |
| Mobile operations & the shadow vehicleOnly DTCD | §630.1108 | Moving Operations captures the traveling work zone live — position, projected route, workers present — that no planning-based system can see, and produces the record that the shadow vehicle / TMA was trailing the crew. This is how you document the mobile-operation protection Subpart K calls for. |
| Worker exposure control | §630.1108 | Opt-in worker-presence pings record who was on foot inside the zone, and when. |
| Flagging & law-enforcement measures | §630.1108 | Documents flagger stations and checks for the STOP/SLOW paddle and advance flagger warning (W20-7). |
| Device maintenance | §630.1110 | The inspect-and-correct trail records each deficiency found and the re-check that closed it out. |
| Related federal rule | ||
| Worker high-visibility apparel | 23 CFR 634 | AI photo analysis flags any worker in frame without visible ANSI/ISEA 107 high-visibility apparel. |
DTCD supports compliance with these provisions by producing and maintaining the required records and the standards-based data feed; it does not replace trained personnel, temporary-traffic-control device placement, or positive protection. General information, not legal advice — confirm requirements with the contracting agency. See the full write-up in The 2026 Work-Zone Documentation Deadline.
DTCD generates your state's required daily traffic-control record from the field — GPS-tagged, photo-backed, in one tap — and publishes a live WZDx/CWZ work-zone data feed while you're at it.
