Houston DOT Safety Compliance for Trucks

What are we going to find into this post:

• What applies and why it’s different in Houston: FMCSA sets your baseline (HOS/ELD, DQF, D&A, cargo securement), but Texas intrastate rules can differ (e.g., 12/15 vs. federal 11/14). Expect active local enforcement—HPD Truck Enforcement Unit and TxDPS CVE run CVSA-style inspections inside the city, so know whether a trip is interstate or intrastate before you run the clock.
• Registrations, authority & permits to have ready: For Texas-only work get a TxDMV intrastate number; for interstate get USDOT/MC and UCR. OS/OW moves need TxDMV permits and a Houston city permit for city streets—plan routes and escorts early. Keep BOC-3, filings (BMC/MCS-90) and COIs organized and retrievable.
• Daily/weekly actions that prevent violations: Run a 60-minute weekly HOS/ELD audit (export logs → triage → coach → fix hygiene → document), confirm ELD is FMCSA-registered and configured, maintain DQFs with 90/60/30 alerts, run drug & alcohol program controls, and close DVIRs into PM tickets. Simplex Group provides Houston-tailored ELD setup, filings, OS/OW coordination, weekly audits, and one-click audit packets so you stay inspection-ready.

Houston is a major freight hub—Port of Houston, petrochemical corridors, and busy beltways mean more inspections and stricter attention to safety basics. Below is a practical, Houston-focused guide to DOT safety compliance, plus where Simplex Group plugs in to keep you audit-ready while you keep freight moving.

Federal vs. Texas vs. Houston: What actually applies?

• FMCSA = your baseline. Hours of Service (HOS), ELD, Driver Qualification Files (DQF), Drug & Alcohol testing, cargo securement—these are your core federal rules.
• Texas intrastate rules mirror FMCSA with key differences. For intrastate operations (staying within Texas), drivers may drive up to 12 hours after 8 off and can’t drive after 15 hours on duty (vs. the federal 11/14 framework). Know which set applies to your trip.
• Local enforcement is active. The Houston Police Department’s Truck Enforcement Unit conducts CVSA-standard inspections across the city, certified via TxDPS/FMCSA—expect real scrutiny inside city limits.

Simplex Group advantage: We configure your HOS/ELD and audit routines to align with your actual operating pattern (interstate vs. intrastate), so drivers follow the right clock and you avoid avoidable violations.

Registrations, authority, and permits for Houston

• Intrastate authority: If you operate CMVs only within Texas, you need a TxDMV (intrastate) number. For interstate moves, you also need federal authority (USDOT/MC).
• UCR: If you run interstate, register annually under the Unified Carrier Registration (UCR) program; proof in cab isn’t required, but you may keep a receipt.
• Oversize/overweight (OS/OW): Texas issues OS/OW permits via TxDMV, and Houston requires an additional city permit to travel on city streets—coordinate routes and any escort requirements in advance.

Simplex Group helps: Authority setup (TxDMV + USDOT/MC), UCR filings, OS/OW coordination, and renewal tracking—so your paperwork doesn’t slow your loads.

HOS & ELD Audit for your Houston Trucking Company: A weekly rhythm that works

A one-hour weekly cadence keeps your CSA stable and coaching proactive:

1. Pull data (5 min): Export last week’s logs and exceptions (11/14 or 12/15 hits, 30-min break misses, unidentified driving, edits).
2. Triage by risk (10 min): Focus on repeat patterns first—Friday 11-hour hits, PC/yard-move misuse, late sign-offs.
3. Coach (20 min): Meet the top 3–5 drivers by violations; align on one improvement for the coming week.
4. Fix hygiene (10 min): Clear unidentified driving, correct unit assignments, close open DVIRs.
5. Close the loop (15 min): Log coaching, track trends, share a “win of the week.”

How Simplex Group fits: Our Simplex ELD makes HOS intuitive; our HOS & ELD Audit services surface exceptions automatically and hand you prioritized coaching notes. We’ll also maintain the supporting documents you need if an audit lands on your desk.

DQF, Drug & Alcohol, and maintenance compliance

• DQF: Keep a complete, standardized Driver Qualification File per driver (application, MVRs, med card, prior employer checks, road test/CDL proof, training acknowledgments). Use 90/60/30-day reminders for renewals.
• Drug & Alcohol: CDL drivers in interstate or intrastate commerce must be in a DOT testing program; owner-operators must join a consortium. Use the FMCSA Clearinghouse correctly and train supervisors for reasonable suspicion. 
• DVIR & PM: Pre/post-trip inspections, prompt defect repair, and a preventive maintenance schedule tied to duty cycles.

Simplex Group service stack: DQF build-out and audits, Drug & Alcohol program administration, Clearinghouse support, and maintenance-DVIR workflows—organized in audit-ready, digital folders.
