Truck dispatching is one of the fastest-growing roles in the logistics industry. Dispatchers are the operational backbone of trucking companies and freight brokerages — coordinating loads, managing drivers, ensuring regulatory compliance, and keeping cargo moving on schedule. The work requires knowledge of federal transportation regulations, freight systems, geography, carrier relations, and customer communication all at once. Practice tests help you build that knowledge systematically.

What Does a Truck Dispatcher Do?

A truck dispatcher connects shippers (companies with freight to move) with carriers (trucking companies with available equipment). On any given day, a dispatcher might be posting loads on load boards, negotiating rates with carrier representatives, tracking shipments in transit, resolving delivery problems, updating customers on ETAs, and ensuring every driver in their fleet stays compliant with Hours of Service regulations.

Dispatchers working for trucking companies manage their own fleet — monitoring driver locations, hours, and load assignments. Dispatchers working as freight brokers represent shippers and find carriers on the spot market or through contracted relationships. The skills overlap substantially, but the regulatory distinctions matter when you're answering certification exam questions.

Load Planning and Routing

Effective load planning maximizes revenue per mile while minimizing deadhead (empty miles). A skilled dispatcher looks at available loads geographically, matches them to available trucks and drivers, and builds routes that minimize the distance driven without freight.

Routing decisions factor in: HOS (a driver who's been on duty for 9 hours can't take an 11-hour run), equipment type (flatbed loads can't go on a dry van), hazmat endorsements, bridge weight limits on certain routes, and customer delivery time windows. The best dispatchers think two loads ahead — booking the return load before the outbound delivery is complete.

Load planning also involves weight and dimension compliance. The standard gross vehicle weight limit on Interstate highways is 80,000 lbs. Oversized loads (over-dimensional, overweight) require permits, escort vehicles, and restricted travel times (typically daylight hours only, no travel on weekends or holidays in many states). Dispatchers need to know when a load needs a permit and how to arrange one.

Transportation Management Systems (TMS)

Modern dispatching is software-driven. A Transportation Management System (TMS) is the central platform that tracks loads, drivers, invoices, and compliance. Major TMS platforms include McLeod, TMW Suite, Samsara, KeepTruckin (now Motive), and Alvys. Each has its own interface, but all perform the same core functions: load tracking, driver communication, document management, and reporting.

TMS proficiency is tested on dispatcher assessments because it's directly tied to job performance. You should understand the general workflow: creating a load, assigning it to a driver, tracking its progress, generating a BOL (bill of lading), and closing the load when it delivers. Electronic logging devices (ELDs) feed HOS data into TMS platforms in real time.

DOT Regulations and Hours of Service (HOS)

FMCSA's Hours of Service regulations define how long a commercial driver may operate before taking mandatory rest. These rules are among the most frequently tested topics on dispatcher exams. The current federal HOS rules for property-carrying drivers include:

• 11-hour driving limit — may drive up to 11 hours after 10 consecutive hours off duty
• 14-hour on-duty limit — may not drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty
• 30-minute break requirement — must take a 30-minute break when 8 cumulative hours have passed since last off-duty or sleeper berth period
• 60/70-hour limit — may not drive after 60/70 hours on duty in 7/8 consecutive days (depending on whether the carrier operates 7 or 8 days a week)
• 34-hour restart — drivers can restart the 60/70-hour clock with a rest period of at least 34 consecutive hours

Dispatchers are legally prohibited from requiring or knowingly allowing a driver to violate HOS rules. Asking a driver to push past their available hours, even subtly, creates co-liability for the company and the dispatcher personally. Exam questions often present a scenario where a dispatcher is tempted to squeeze more miles out of a tired driver — the correct answer is always to comply with HOS rules.

Freight Classification (NMFC)

The National Motor Freight Classification (NMFC) system assigns a class (50–500) to every type of freight. The class determines the base rate for LTL shipments. Classes are determined by four factors: density, stowability, handling, and liability.

Low-density, fragile, or hazardous items get high class numbers (and higher rates). Dense, durable freight gets low class numbers (and lower rates). A dispatcher quoting LTL rates must know or look up the correct NMFC class. Misclassifying freight is a common error that leads to invoice disputes, reclassification charges, and strained customer relationships.

For exam purposes, understand the conceptual framework: class 50 freight (like scrap metal) is the cheapest to ship per pound; class 500 (like ping-pong balls) is the most expensive. Know that four factors determine class and be able to identify how they apply to a given freight type.

LTL vs FTL (Full Truckload)

LTL (Less-than-Truckload) freight doesn't fill an entire trailer. Multiple LTL shipments from different shippers ride together on the same truck, with freight transferred through regional distribution centers (terminals). LTL pricing is based on weight, class, distance, and accessorial charges. Transit times are longer due to the hub-and-spoke network.

FTL (Full Truckload) dedicates an entire trailer to one shipper's freight. The truck goes directly from pickup to delivery without intermediate stops. Pricing is per-mile or flat-rate. Transit times are faster and more predictable.

Dispatchers must know when to recommend LTL vs FTL. General guidance: under 10,000 lbs, LTL is usually more economical. Over 20,000 lbs, FTL is usually cheaper per pound. Between 10,000 and 20,000 lbs, it depends on density, class, and timing. Exam scenarios often present weight and ask which mode is appropriate.

Carrier Relations and Broker Authority

Freight brokers legally require FMCSA broker authority (an MC number) to arrange transportation for compensation. Applying for broker authority requires a $75 application fee, proof of a $75,000 surety bond (BMC-84) or trust fund (BMC-85), and designation of a process agent in each state. The MC number must be active and maintained — failure to renew the bond results in automatic revocation.

Dispatchers who work for asset-based carriers (they own trucks) don't need broker authority — they're dispatching their own equipment. But many independent dispatchers set up as brokers or work for brokerages. Understanding the distinction between carrier authority and broker authority matters for exam questions about what actions require which type of licence.

Building carrier relationships is a core dispatcher skill. Consistent carriers with good safety records are worth paying a few cents per mile more than spot market strangers. Track carrier performance: on-time percentage, check-call compliance, cargo claims history. The exam may present scenarios about vetting new carriers — at minimum, verify active DOT authority, adequate insurance (at least $750,000 cargo for general freight), and no "conditional" or "unsatisfactory" safety ratings.

Load Boards: DAT, Truckstop.com, and Others

Load boards are online marketplaces where brokers post available loads and carriers search for freight. DAT (Dial-A-Truck) and Truckstop.com are the two dominant platforms in the US. Both offer real-time rate data, load posting, and carrier/broker search tools.

Load boards display: origin/destination, commodity, equipment type required, weight, length, number of stops, rate (if posted), and poster contact information. Dispatchers use load boards to find backhaul freight, fill empty trucks, or cover loads when their contracted carriers can't deliver.

Rate benchmarking using load board data helps dispatchers negotiate fair rates with both carriers and shippers. DAT's rate analytics tool shows average rates paid per lane over the past 13 months — essential data for quoting shippers competitively and negotiating with carriers profitably.

Tracking and Tracing Shipments

Customers expect real-time shipment visibility. Dispatchers are responsible for providing accurate ETAs, resolving delays, and communicating proactively when something goes wrong. The check-call system — where drivers report their location and status at regular intervals — is the traditional method. ELDs and GPS tracking provide automated location data on most modern fleets.

When a shipment is late, the dispatcher's job is to: get accurate current location from the driver, recalculate ETA, notify the customer immediately (before they call you), and determine whether the delay can be recovered through adjusted routing, extended driving hours (if HOS allows), or whether a missed delivery window is inevitable. Exam scenarios about customer communication test whether you understand that proactive notification is always better than reactive explanation.

FMCSA Regulations Beyond HOS

Beyond HOS, dispatchers should understand several other FMCSA regulatory areas:

Drug and alcohol testing — Carriers must have a DOT drug and alcohol testing program. Pre-employment, random, post-accident, reasonable suspicion, and return-to-duty testing are all required. Dispatchers need to know they cannot dispatch a driver who hasn't cleared pre-employment testing or who has tested positive without completing the return-to-duty process.

Driver qualification files — Carriers must maintain files for each driver containing employment application, MVR (motor vehicle record), road test certificate, medical certificate, and annual review of driving record. Dispatchers typically don't manage these directly, but exam questions may test awareness of what they contain.

Vehicle maintenance — CMVs must pass pre-trip inspections before every trip. Dispatchers should not dispatch a truck with known defects listed on a driver vehicle inspection report (DVIR). Dispatching a truck with a known defect that then causes an accident creates significant liability.

Rate Negotiation and Freight Market Dynamics

Freight rates fluctuate with supply and demand. A dispatcher negotiating carrier rates needs to understand spot market vs contract pricing. Spot rates are current market rates for single loads; contract rates are negotiated for a lane over 12 months. In tight markets (high demand, low capacity), spot rates exceed contract rates. In soft markets, spot rates fall below contract.

From the broker side: buy low (from carriers), sell high (to shippers). Margin is everything. A typical broker margin is 10–20% of the load. Knowing your lane costs — fuel surcharges, tolls, transit time — helps you price competitively while protecting margin.
