The Complete Trucking Compliance Guide for Dispatchers in 2025
Compliance is not the most exciting topic in truck dispatching — but it is one of the most consequential. A carrier with compliance problems cannot get loads from quality brokers. A carrier whose authority gets revoked cannot haul anything legally. A carrier whose ELD malfunctions during a load faces roadside inspection penalties that ground the truck. And a dispatcher who does not understand compliance well enough to guide their carriers through these issues is a dispatcher who will eventually lose those carriers to problems that were entirely preventable.
This guide covers every compliance area that a professional truck dispatcher must understand — not to operate trucks themselves but to serve as a knowledgeable advisor to their carriers manage broker expectations and recognize compliance problems before they become business-ending crises. By the time you finish this guide compliance will not feel like a foreign regulatory maze. It will feel like a manageable set of rules that you understand and can navigate professionally on behalf of every carrier you work with.
The FMCSA — Understanding Who Regulates Trucking
The Federal Motor Carrier Safety Administration — FMCSA — is the US Department of Transportation agency responsible for regulating commercial motor vehicles operating in interstate commerce. The FMCSA sets and enforces safety standards for carriers drivers vehicles and the overall transportation system. Every carrier you dispatch must be registered with the FMCSA and must maintain ongoing compliance with FMCSA regulations or risk having their operating authority suspended or revoked.
As a dispatcher you interact with FMCSA data constantly — verifying carrier authority on Safer Web checking insurance filing status reviewing CSA safety scores and monitoring authority status changes for your active carriers. The FMCSA is not just a regulatory body — it is the database that brokers use to verify carrier legitimacy before assigning loads and the system that determines whether your carrier can legally haul freight at all.
💡 Dispatcher Rule: Check every carrier's FMCSA record at safer.fmcsa.dot.gov before onboarding and monitor it monthly during the active relationship. Authority status changes and insurance lapses appear here first — catching them early prevents the load disruptions that come from discovering a compliance problem when a broker rejects your Rate Con confirmation.
CSA Scores — What They Are and Why They Matter
CSA stands for Compliance Safety Accountability — the FMCSA's safety measurement and monitoring system. CSA scores are calculated for every carrier based on data from roadside inspections traffic violations crash reports and investigation results. The scores are publicly visible at ai.fmcsa.dot.gov and are used by brokers shippers and carriers to assess safety performance.
CSA measures carrier performance across seven categories called BASICs — Behavior Analysis and Safety Improvement Categories. Each BASIC generates a percentile score from 0 to 100 — where a higher percentile means worse performance relative to other carriers of similar size and operation type. A score of 65 or above in any BASIC typically triggers increased regulatory scrutiny. Scores of 80 or above in certain BASICs trigger FMCSA intervention investigations.
Unsafe Driving
Speeding reckless driving improper lane changes. Most heavily weighted by brokers when evaluating carriers. High scores here are the most common reason TQL and CH Robinson decline new carrier setup.
Hours of Service
HOS log violations false logs record-keeping failures. Directly impacts load acceptance because brokers know HOS-violating carriers are operating in ways that create safety and legal liability.
Driver Fitness
Operating without valid CDL operating while disqualified improper license class for vehicle. A high score here can immediately ground a carrier until the underlying licensing issue is resolved.
Controlled Substances
Drug and alcohol violations. Any positive test result creates immediate disqualification and a long resolution process. Carriers with violations here face significant broker resistance.
Vehicle Maintenance
Brake violations tire violations lighting violations equipment defects. High scores indicate a carrier whose truck is likely to be placed out of service at roadside inspections — grounding loads mid-transit.
Hazardous Materials
Only relevant for carriers transporting hazmat. Packaging labeling placarding violations. Most dispatchers working with standard dry van or reefer carriers will not encounter this BASIC frequently.
How Dispatchers Use CSA Data
During carrier onboarding pull CSA scores for every carrier at ai.fmcsa.dot.gov. If Unsafe Driving or HOS scores are above 65 have an honest conversation with the carrier before proceeding. Some carriers have elevated scores from violations that are months old and their score is actively improving. Others have scores reflecting ongoing operational patterns that will continue generating problems. Understand which situation you are dealing with before committing to a carrier relationship.
For active carriers check CSA scores monthly. A sudden increase in a BASIC score — particularly Unsafe Driving or Vehicle Maintenance — signals a compliance problem that will soon affect load access from quality brokers. Alerting your carrier to an increasing score before brokers start declining them gives the carrier a chance to address the underlying issue proactively rather than reactively after losing access to their best load sources.
Hours of Service — The Rules Every Dispatcher Must Know
Hours of Service regulations govern how many hours a commercial truck driver can drive and be on duty in any given day and week. These regulations exist to prevent fatigue-related accidents — commercial trucks are deadly when driven by fatigued operators — and they are enforced through ELD records that are checked at roadside inspections and by enforcement officers.
As a dispatcher you must understand HOS rules for one critical operational reason: every load you book must be physically achievable within your carrier's remaining legal driving hours. A delivery appointment that requires 16 hours of driving in a 14-hour on-duty window is a legal HOS violation. If you book that load and your driver gets inspected mid-route they face fines and potentially a citation that affects their CSA score. Understanding HOS prevents you from inadvertently booking your carriers into compliance violations.
| HOS Rule | Property Carrying Driver | What It Means for Dispatching |
|---|---|---|
| 11-Hour Driving Limit | Maximum 11 hours driving after 10 consecutive hours off duty | Never book a load requiring more than 11 hours of driving without a rest break opportunity |
| 14-Hour On-Duty Window | Cannot drive beyond the 14th hour after coming on duty | Total on-duty time including loading unloading and driving cannot exceed 14 hours |
| 30-Minute Break | Required after 8 cumulative hours of driving | Factor 30-minute breaks into transit time calculations on longer runs |
| 60/70 Hour Limit | 60 hours on duty in 7 days or 70 hours in 8 days | Carriers running 5+ days per week approach weekly limits — factor this into load planning |
| 10-Hour Off Duty | Must have 10 consecutive hours off before driving again | Overnight loads that arrive early morning require driver was off duty the previous night |
| 34-Hour Restart | 34 consecutive off-duty hours resets weekly 60/70 hour clock | Carriers who have used their weekly limit can restart with 34 hours off — plan accordingly |
Practical HOS Checklist Before Confirming Any Load
Before confirming any load that has tight delivery timing verify: how many hours of driving does this load require — is that achievable within the 11-hour daily limit — what is the distance from the carrier's current location to the pickup — does the carrier have enough HOS remaining today to reach pickup without a rest break — and is the total transit time from pickup to delivery achievable within available on-duty hours including required breaks.
This verification takes two minutes with Google Maps distance data and takes one more minute to confirm with the carrier verbally. The cost of skipping it — a citation during roadside inspection — can add negative inspection data to the CSA score that affects broker access for months.
ELD Requirements — Electronic Logging Devices
Since December 2017 most commercial motor vehicles engaged in interstate commerce have been required to use Electronic Logging Devices — ELDs — to record Hours of Service data instead of paper logs. An ELD connects to the truck's engine and automatically records driving time engine activity vehicle movement and location data in tamper-resistant digital logs.
As a dispatcher you need to know which ELD provider your carriers use for two reasons. First some brokers require specific GPS tracking apps — Macropoint or FourKites — that integrate with the carrier's ELD or run separately on the driver's smartphone. If a load requires Macropoint tracking and your driver does not have it installed you cannot confirm that load until the driver downloads and activates the app. Confirm GPS tracking capability before accepting loads from brokers with tracking requirements.
Second ELD malfunctions can create HOS compliance issues even when the driver is genuinely compliant. If a carrier's ELD malfunctions during a load they must switch to paper logs for a maximum of 8 days while the ELD is repaired. During that period they carry the malfunction documentation with them. Alert your carrier to this protocol when you first onboard them — many new owner-operators are unaware of the malfunction paper log process and panic when their device fails during a load.
Insurance Compliance — The Career-Ending Risk
Insurance compliance is the single highest-stakes compliance area for a truck dispatcher. A carrier whose insurance lapses — even for one day — faces automatic MC authority suspension. And an insurance lapse that you as the dispatcher should have caught but did not reflects directly on the quality of your professional service.
Minimum Insurance Requirements
Property carrying carriers — dry van reefer flatbed — must maintain minimum public liability insurance of $750,000 per occurrence for general freight. For carriers hauling certain types of cargo the minimum rises: $1,000,000 for household goods movers and $5,000,000 for carriers transporting certain hazardous materials. Most quality brokers require $1,000,000 liability regardless of cargo type as a standard operating practice.
Cargo insurance minimums are $5,000 for household goods carriers and $10,000 for general freight carriers — though most brokers require $100,000 in cargo insurance as a practical minimum for load assignment. Many premium brokers and shippers require $250,000 or higher.
The Insurance Lapse Prevention System
Set calendar reminders 60 days before every carrier's insurance renewal date. At 60 days send a reminder to your carrier that their renewal is approaching. At 30 days contact the carrier's insurance agent directly to confirm the renewal policy is being prepared. At 14 days request the new COI from the insurance agent and submit it to all active brokers before the old policy expires. At 7 days confirm with each major broker that their records show the updated policy. At renewal date verify the FMCSA system shows the new policy active.
This five-step sequence costs about 30 minutes per carrier per year and prevents the complete loss of broker access that follows an insurance lapse. One prevented insurance lapse saves more income than weeks of load-finding work.
60 Days Before Renewal
Send carrier reminder that insurance renewal is approaching — confirm they are renewing with same or better coverage levels
30 Days Before Renewal
Contact insurance agent directly — confirm renewal policy is prepared and BMC-91 will be filed before expiry date
14 Days Before Renewal
Request new broker-specific COIs for all active brokers — submit to all brokers before old policy expires
7 Days Before Renewal
Confirm each major broker has received and processed the new COI — no gaps in broker system records
Renewal Date
Verify FMCSA safer.fmcsa.dot.gov shows new policy active and correctly recorded — no lapse in the federal record
Authority Maintenance — Keeping the MC Number Active
Operating authority can be revoked not just through insurance lapses but through several other compliance failures that dispatchers need to monitor for their carriers.
The MCS-150 biennial update is required for all carriers to keep their USDOT number active. Every two years carriers must file an updated MCS-150 form with the FMCSA confirming their operating information — company details vehicle counts drivers and operating areas. Missing this update deactivates the USDOT number which deactivates the MC authority. Set a calendar reminder for each carrier's MCS-150 due date and send them a reminder 60 days in advance.
The BOC-3 process agent designation must remain active at all times. If a carrier's registered process agent service lapses or their BOC-3 is cancelled for any reason their authority can be suspended. Confirm the BOC-3 is on file and current during your annual compliance review for each carrier.
Unsatisfactory safety ratings — the most severe FMCSA safety rating — result from formal FMCSA investigation and can lead to authority revocation if not addressed through the administrative correction process. While this is relatively rare it is not unheard of for carriers with persistently high CSA scores who attract FMCSA investigation attention. Monitor CSA scores to catch patterns that might lead to investigation before they reach that stage.
