Trucking in the US is one of the most heavily regulated industries. DOT and FMCSA oversee every aspect: from a driver's hours of service to the condition of the tires. A dispatcher is required to know these rules — because it's the dispatcher who plans the routes and the timing. An HOS violation caused by the dispatcher = a fine of up to $16,000 and loss of your authority.
The dispatcher isn't behind the wheel, but bears direct responsibility for compliance. It's the dispatcher who plans the route, sets the pickup and delivery times, and decides whether a driver can take a given load or won't have enough HOS to make it. If a dispatcher books a load that can't be delivered without violating HOS, the responsibility falls on the dispatcher.
Coercion Rule (49 CFR 390.6): FMCSA can fine a dispatch company or a broker for pressuring a driver to break the rules. If a driver says "I don't have enough hours," and the dispatcher responds "drive anyway, or you'll lose your job" — that's coercion. Fine: up to $16,000 per incident. The driver can file a complaint with FMCSA anonymously. This isn't just theory — FMCSA actively pursues these cases.
What a dispatcher needs to know: HOS rules (so you don't plan impossible routes). CSA scores (to understand the carrier's standing). ELD (to read a driver's logs). Insurance (to know coverage when incidents happen). Fines (to understand the cost of a mistake). State weight limits (so you don't send out an overweight truck). Hazmat rules (if you haul hazardous materials).
A real-world example: A driver delivered a load in Atlanta at 2:00 PM. He has 3 hours of driving left. You found a load Atlanta → Charlotte (250 miles, ~4.5 hours). If you book that load, the driver won't be able to deliver it without violating HOS. That's your responsibility as a dispatcher. The right call: find a load of 150 miles or less, or schedule delivery for the next day.
DOT (Department of Transportation) — the US federal transportation department. It oversees every mode of transport: aviation, railroads, maritime, and highway. DOT sets the broad standards for safety and infrastructure. Every commercial carrier is required to have a USDOT number — a unique identifier used for safety tracking and audits.
FMCSA (Federal Motor Carrier Safety Administration) — a division of DOT that specifically regulates freight and passenger motor carriers. FMCSA is the "police force" of the trucking industry. They issue authority (MC#, broker authority), set the HOS rules, enforce ELD compliance, run inspections, maintain the CSA scores database, investigate crashes, and penalize violators.
How inspections work: DOT officers conduct roadside inspections at weigh stations and on the road. There are 6 inspection levels: Level I — a full driver + vehicle inspection (45-60 min). Level II — a walk-around (driver check + external vehicle inspection, 30 min). Level III — driver only (documents, HOS, drug test, 15 min). Level IV — a special inspection. Level V — vehicle only (no driver). Level VI — hazmat. The results of every inspection feed into the carrier's CSA score.
What FMCSA regulates: Authority (MC#, USDOT#, broker authority). Hours of Service (HOS). Electronic Logging Devices (ELD). Drug & Alcohol testing. Vehicle maintenance standards. Insurance requirements. CSA safety scores. Hazardous materials transportation. Carrier fitness and compliance reviews.
HOS are the most important rules for a dispatcher. They define how many hours a driver can drive, when the driver must rest, and when the driver must stop completely. An HOS violation is one of the most common and expensive violations in trucking. Fine: $1,000-$16,000. Out-of-service order: the driver can't move until hours reset. CSA points: they stay on the record for 2 years.
The key for a dispatcher: Before every booking, check the driver's HOS via the ELD. Ask: "How many driving hours do you have left?" and "When did your 14-hour clock start?" If the driver says "I've got 6 hours," don't book a load that takes 7 hours to run. It seems obvious, but that exact mistake causes 80% of HOS violations.
The driver starts the shift at 6:00 AM. Here's what the day looks like under the HOS rules:
🔵 Driving: 11h max | 🟠 On-duty (not driving): loading, unloading, pre-trip | 🟡 30-min break: required after 8h of driving | 14-hour window: from 6:00 AM to 8:00 PM — after that you CANNOT drive, even if you have driving hours left.
A driver can drive a maximum of 11 hours after 10 consecutive hours off-duty. This is DRIVING time — time behind the wheel. Don't confuse it with on-duty time (loading, unloading, waiting — that's on-duty, but not driving). Example: a driver rested from 8 PM to 6 AM (10 hours). Starting at 6 AM he can drive 11 hours = until 5 PM. But only if he doesn't spend time on on-duty tasks (loading, etc.).
This is THE most misunderstood rule. The 14-hour window starts the moment a driver goes from off-duty to on-duty (or driving). From then on he has 14 hours — and he CANNOT drive after 14 hours, EVEN IF he's only used 8 of his 11 driving hours. Example: a driver started at 6 AM. At 8 PM (14 hours) he MUST stop, even if he only drove 6 hours and spent the rest of the time waiting to load. The 14-hour clock does NOT pause for breaks or on-duty time — it ticks continuously.
After 8 hours of driving (not on-duty — driving specifically) a driver must take at least a 30-minute break. The break can be off-duty or on-duty (not driving) — waiting to load, for example, counts. Without this break, the driver can't keep driving. Tip for the dispatcher: schedule loading/unloading so it lands right around the 8-hour mark — that's a "free" break.
Two options: 60 hours on-duty over 7 consecutive days OR 70 hours over 8 days. Most carriers use 70/8. On-duty includes EVERYTHING: driving + loading + waiting + pre-trip. Example: a driver worked 5 days at 14 hours on-duty = 70 hours. On day 6 he CANNOT work until he does a 34-hour restart or until the older hours "roll off" (rolling 8-day window).
A driver can "reset" the 60/70-hour clock by taking 34 consecutive hours off-duty. After the restart, all the hours zero out, as if the week were starting fresh. Example: a driver finished Friday at 6 PM. 34 hours off-duty = until Sunday 4 AM. From Sunday 4 AM he has a full 70 hours for the new week. Tip: schedule the restart over the weekend — the driver rests, the hours reset.
A driver can split the 10-hour off-duty period into two: a 7/3 or 8/2 split. At least 7 hours in the sleeper berth + at least 2 hours off-duty (or in the sleeper). Neither period counts against the 14-hour window. This lets the driver "stretch" the workday. New in 2026: FMCSA is testing pilot programs for 6/4 and 5/5 splits for even more flexibility.
For drivers who operate within a 150 air-mile radius of the terminal and return every day: no ELD required, no Record of Duty Status required. But: the 14-hour duty window still applies, and the driver must return to the terminal within 14 hours. Useful for local/regional operations.
If a driver runs into unexpected weather (snow, fog, ice) or road problems (a crash, a road closure), he can extend the driving limit by 2 hours (up to 13 hours of driving) and the duty window by 2 hours (up to 16 hours). The condition: the situation must be unforeseen (not "I knew snow was coming, but I drove anyway"). The driver must flag it in the ELD.

CSA (Compliance, Safety, Accountability) is FMCSA's system for rating carrier safety. Every carrier gets scored across 7 BASIC categories based on inspection results, crashes, and violations. The scale runs 0-100, where 0 is the best result. Scores above the threshold (65-80 depending on the category) trigger FMCSA intervention: warnings, targeted inspections, audits, and even shutting the company down.
Why CSA matters to a dispatcher: A poor CSA score for the carrier = higher insurance costs (by 20-50%), brokers refusing to work with you (large brokers check CSA before booking), more roadside inspections (DOT officers deliberately pull over trucks with bad CSA), and ultimately — loss of business. Check CSA at ai.fmcsa.dot.gov.
2025 changes (now in effect): FMCSA reorganized the CSA system. The BASICs were renamed to "compliance categories." Violation weights were simplified. There's a greater focus on recent violations (the last 12 months carry more weight). The goal is a fairer comparison between carriers of different sizes. In 2026 the system continues to operate in the updated format.
Speeding, reckless driving, using a phone behind the wheel, improper lane change, failure to use a seatbelt. The most "expensive" category — directly linked to crashes. Each violation adds 1-10 points.
Counts all DOT-reportable crashes over the last 24 months. Even if the driver isn't at fault, the crash goes into CSA. The only way to lower it is time (points "age off") and a DataQs challenge (a dispute).
Hours of Service violations: driving beyond limits, falsifying logs, no ELD, incomplete records. For a dispatcher, this is the most relevant category. Your planning directly affects the driver's HOS compliance.
The truck's condition: brakes, tires, lighting, frame, coupling devices. Caught during roadside inspections. The 80% threshold is the highest, because poor maintenance = a direct safety threat.
Positive drug/alcohol tests, refusal to test, possession of controlled substances. The most serious consequences: immediate out-of-service, loss of CDL, criminal liability.
Violations in hauling hazardous materials: incorrect labeling, missing placards, leaks, improper loading. Applies only to hazmat carriers. Fines are especially high — up to $75,000.
Driver qualifications: a valid CDL, medical certificate, proper endorsements. An expired CDL or medical card = out-of-service. The dispatcher should track the expiration dates on drivers' documents.
An ELD (Electronic Logging Device) is a device that automatically records a driver's driving time by connecting to the truck's engine. The ELD mandate has been in effect since December 2019 — all commercial carriers are required to use a certified ELD. Paper logbooks are no longer accepted (with the exception of the short-haul exception and ELD malfunctions).
What an ELD records: Engine hours (engine run time). Vehicle movement (GPS coordinates). Driver status (driving, on-duty, off-duty, sleeper berth). The start and end time of each status. The ELD stores data for the current day + the 7 previous days (8 days total). During a roadside inspection the driver must show the ELD data to the DOT officer.
Penalties for ELD violations: No ELD — an out-of-service order + a fine of up to $16,000. Tampering (attempting to alter the data) — a fine of up to $16,000 + possible criminal liability. A malfunctioning ELD — the driver can use paper logs for a maximum of 8 days, then it's out-of-service. The driver must keep 8 blank paper log sheets in the cab in case the ELD fails.
For the dispatcher: You need to be able to read a driver's ELD data. Before booking, ask: "Show me your ELD — how many hours do you have left?" Many TMS systems integrate with ELDs and show drivers' HOS status in real time. Popular ELDs: Motive (KeepTruckin), Samsara, Omnitracs, ELD Rider. Cost: $20-45/month for the device + subscription.
Insurance is a mandatory condition for operating in trucking. Without the right coverage a carrier won't get MC authority, can't work with brokers, and risks losing everything in a crash. FMCSA sets the minimum requirements, but many brokers demand coverage above the minimum.
Covers third-party damage in a crash: property damage, injuries, death. FMCSA minimum: $750,000 for general freight, $1,000,000 for hazmat, $5,000,000 for certain hazmat classes. Most brokers require $1M even for general freight. Cost: $8,000-$15,000/year for a new carrier.
Covers the value of the freight in case of damage, theft, or loss. FMCSA minimum: $100,000. But if you're hauling electronics ($500K+ per trailer), $100K won't cover it. Many brokers require $250K-$500K. Cost: $1,500-$3,000/year. Important: check the exclusions — some policies don't cover reefer breakdown.
Covers repairing or replacing YOUR truck after a crash, fire, theft, or vandalism. Not required by FMCSA, but if the truck is leased, the leasing company requires it. Two types: Collision (a crash) and Comprehensive (everything else). Cost: 3-5% of the truck's value per year.
Covers general business risks: an injury on company premises, errors in paperwork, client claims. Not required by FMCSA, but many brokers and shippers demand it. Cost: $500-$2,000/year. Recommended for dispatch companies.
Required in most states if you have hired employees (not owner-operators). Covers medical costs and lost income from a workplace injury. Owner-operators are usually exempt, but some states require it even for them.
Fines in trucking are serious. A single violation can cost anywhere from $1,000 to $75,000. Beyond the money — out-of-service orders (the driver/truck can't move), CSA points (they stay for 2 years), higher insurance, loss of customers, and in extreme cases — criminal liability.
| Violation | Fine | Consequences |
|---|---|---|
| HOS violation (driving) | $1,000-$16,000 | Out-of-service, CSA points, repeat = loss of CDL |
| No ELD / tampering | $1,000-$16,000 | Immediate out-of-service, possible criminal case |
| Coercion (pressuring the driver) | $16,000 | Fine on the dispatch company/broker, FMCSA investigation |
| Operating without authority | $25,000+ | Truck impoundment, criminal liability |
| No insurance | $16,000+ | Immediate shutdown of operations, loss of MC authority |
| Overweight violation | $1-$10/lb over | Depends on the state. 5,000 lbs over = $5,000-$50,000 |
| Drug/alcohol violation | $2,500-$25,000 | Loss of CDL, criminal liability, out-of-service |
| Hazmat violation | $500-$75,000 | Depends on severity. A leak = a criminal case |
| Failed inspection (OOS) | Varies | Truck/driver can't move until it's fixed. CSA points. |
| Falsifying records | $16,000 | Criminal liability, permanent loss of CDL |
