Knowing the geography is the foundation of a dispatcher's job. Understanding regions, transport hubs, seasonality, and rates by lane lets you find the best loads and build profitable routes for your drivers.
The Interstate Highway System is the circulatory system of American freight. Four major corridors connect the country east to west and north to south. A dispatcher must know each of them: which cities they link, what freight moves along them, where the traffic jams are, where the tolls are, and which seasonal problems to expect. Understanding the corridors means understanding how the money moves in trucking.
The busiest Interstate on the East Coast. It connects every major city on the eastern seaboard: Boston, New York, Philadelphia, Baltimore, Washington DC, Richmond, Jacksonville, Miami. It is the artery for consumer goods, e-commerce, and produce out of Florida.
Challenges: chronic congestion around NYC and DC, high tolls (NJ Turnpike โ up to $100+ for trucks), narrow stretches in Connecticut and Rhode Island. In winter โ snowstorms from Virginia to Maine. Despite the difficulties, I-95 is one of the most profitable corridors thanks to the density of population and business.
The main southern corridor from the Atlantic to the Pacific. It runs through Jacksonville, Tallahassee, Mobile, New Orleans, Houston, San Antonio, El Paso, Tucson, Phoenix, and Los Angeles. Critically important for cross-border freight (Laredo, El Paso) and the oil and gas industry (Houston).
Notable features: West Texas โ 550 miles of nearly empty space between San Antonio and El Paso (a classic deadhead stretch). Hurricane season (JuneโNovember) can shut down sections along the Gulf Coast. In summer, temperatures hit 110ยฐF+ in Arizona โ reefer equipment runs at its limit.
The main artery of the West Coast. It connects San Diego, Los Angeles, Bakersfield, Fresno, Sacramento, Portland, and Seattle. This is the corridor for produce out of California's Central Valley โ the largest agricultural region in the country, producing 50%+ of America's fruits and vegetables.
Key stretches: Grapevine Pass (between LA and the Central Valley) โ closes in winter due to snow. Siskiyou Pass (CA/OR border) โ steep grades, dangerous in winter. CARB compliance is mandatory throughout California. The ports of LA/Long Beach and Seattle/Tacoma generate an enormous volume of container freight.
The main northern transcontinental corridor. It runs through New Jersey, Pennsylvania, Ohio, Indiana, Illinois (Chicago), Iowa, Nebraska, Wyoming, Utah, Nevada, and California (San Francisco). This is the primary route for coast-to-coast freight through the Midwest.
Critical stretches: Wyoming (Elk Mountain, 8,640 ft) โ the strongest winds and snowstorms in winter, the road closes several times a season. Donner Pass in the Sierra Nevada (CA/NV border) โ chain requirements in winter. Ohio Turnpike โ tolls $30+ for trucks. Despite the winter difficulties, I-80 is a key corridor for intermodal and dry van freight.
Beyond the four main corridors, a dispatcher should know several other key Interstates that link regions and create alternate routes.
An alternative to I-10 and I-80. It runs through Raleigh, Nashville, Memphis, Little Rock, Oklahoma City, Amarillo, Albuquerque, Flagstaff. Popular for freight from the Southeast to the Southwest and California. Fewer tolls than I-80. In winter, snow at elevation in New Mexico and Arizona.
The main north-south corridor in the East. Michigan โ Ohio โ Kentucky โ Tennessee โ Georgia โ Florida. It runs through Detroit (auto industry), Cincinnati, Knoxville, Atlanta, Tampa, Miami. Critically important for the Florida produce season (JanuaryโApril) and the automotive supply chain.
Connects the Midwest with Texas and the Mexican border. Minneapolis โ Des Moines โ Kansas City โ Oklahoma City โ Dallas โ San Antonio โ Laredo. Key for NAFTA/USMCA freight. Laredo handles 40% of US-Mexico trade. In winter, Minnesota and Iowa see snowstorms.
Connects the Chicago area with the Gulf Coast through Indianapolis, Louisville, Nashville, Birmingham, Mobile. It runs through Nashville โ one of the fastest-growing logistics markets. Steady demand for consumer goods and construction materials.
The US breaks down into 5 key regions, each with its own freight characteristics. A dispatcher needs to understand which loads dominate each region, what rates to expect, and which seasonal swings to account for. Click a region card to see the details.
The most densely populated region. A huge volume of consumer goods, but tricky logistics due to narrow roads, congestion, and truck restrictions in the cities.
The Northeast is the economic center of the US, with a population of over 55 million. New York, Boston, Philadelphia, and other metro areas create constant demand for goods delivery. But working here takes experience: narrow streets, delivery windows, tolls, and difficult parking.
A fast-growing region with strong logistics infrastructure. Atlanta is one of the country's largest transport hubs. Florida is a key produce market.
The Southeast is experiencing a boom in population and business growth. Companies are relocating warehouses and distribution centers here from the expensive Northeast. Atlanta has become the second most important logistics hub after Chicago. The Port of Savannah is one of the fastest-growing in the country.
The heart of American industry and agriculture. Chicago is the country's largest transport hub. Steady demand year-round.
The Midwest is the "Crossroads of America." More freight passes through Chicago than through any other city. The region produces automobiles (Detroit), farm products (Iowa, Kansas), and industrial goods (Ohio, Indiana). For a dispatcher, it's one of the most predictable regions in terms of volume and rates.
Texas is the second-largest state and one of the biggest freight markets. Dallas, Houston, San Antonio โ powerful hubs with an enormous volume of freight.
Texas is an economy of its own, the size of a small country. Houston is the oil and gas capital, Dallas-Fort Worth is a logistics giant, Laredo is the largest border crossing with Mexico. For a dispatcher, Texas always means freight: oilfield equipment, construction materials, consumer goods, cross-border freight.
California is the largest economy among the states. The ports of LA/Long Beach handle 40% of all US imports. Produce season here lasts almost the entire year.
The West Coast is the gateway for Asian imports and the country's largest producer of farm products. California alone produces more than 50% of all US fruits and vegetables. The ports of Los Angeles and Long Beach are the start of the supply chain for millions of goods. But the region has its own challenges: strict environmental rules (CARB), mountain passes, and long distances.
The least populated region. Long distances between cities, few loads for the return trip. A classic deadhead zone, but with opportunities in season.
Mountain & Plains is a challenge for a dispatcher. The distances are enormous, there are few towns, and there is often no load for the return trip. But during harvest season (grain, sugar beets) rates can be very attractive. Oil regions (the Bakken in North Dakota) also create demand for equipment and materials.
Transport hubs are the cities through which the greatest volume of freight moves. Knowing the hubs helps a dispatcher quickly find loads for drivers and plan routes with minimal deadhead. If your driver is near a hub โ there will always be loads.
The country's largest transport hub. The intersection of I-90, I-94, I-80, I-55, I-57. More intermodal freight passes through Chicago than through any other city. The warehouses of the largest retailers and distributors are located here.
The second-largest freight hub. A strategic location between the East and West Coasts. A huge number of distribution centers. Freight is available in all directions practically year-round.
The main hub of the Southeast. The intersection of I-75, I-85, I-20. The world's busiest airport (Hartsfield-Jackson) generates air freight. Home Depot, UPS, Coca-Cola โ all are based here.
The ports of LA/Long Beach handle 40% of US imports. Container freight fans out across the whole country. Outbound rates are high, but inbound rates are among the lowest (everyone wants to leave CA).
FedEx's home base. The world's largest cargo airport. A strategic location at the intersection of I-40 and I-55. A great point for re-planning routes.
The state's official motto is "Crossroads of America." I-65, I-69, I-70, I-74 all cross here. One of the most convenient hubs for planning routes in any direction.
The center of the oil and gas industry. The Port of Houston โ 2nd-largest by volume in the US. Chemical industry, oilfield equipment, construction materials. Hazmat freight is a common specialty.
One of the largest warehousing markets in the country. Amazon, Walmart, Target โ all have huge distribution centers here. Access to 60% of the US population within 600 miles.
40% of all US-Mexico trade passes through Laredo. Cross-border freight is a growing segment. Freight from Mexico moves north, American goods head south. Specifics: customs clearance, FAST card.
The fastest-growing port on the East Coast. The deepwater port receives the largest container ships. Growing 15% a year. Freight fans out across the entire Southeast and Midwest.
A lane is a route between two points. Some lanes are consistently profitable, others are seasonal. Understanding headhaul (the direction with high demand) and backhaul (the return direction with low demand) is critically important for maximizing a driver's income. Below are the key lanes with filtering by type.
| Lane โ | Distance โ | RPM โ | Type | Season | Notes |
|---|---|---|---|---|---|
LA, CA โ Dallas, TX |
1,435 mi | $2.80 | Headhaul | Year-round | Steady demand, import freight from the port |
Dallas, TX โ LA, CA |
1,435 mi | $1.60 | Backhaul | Year-round | Low demand, everyone is leaving CA |
Chicago, IL โ Atlanta, GA |
716 mi | $2.60 | Headhaul | Year-round | Consumer goods, e-commerce |
Atlanta, GA โ Miami, FL |
662 mi | $2.20 | Headhaul | Year-round | Retail, construction materials for the growing FL market |

The continental US has 4 time zones. This is critically important for a dispatcher: pickup and delivery times are given in local time. If you work from Eastern Time and your driver is on Pacific โ that's a 3-hour difference. A time-zone mistake can cost you the load and your reputation.
NY, FL, GA, OH, PA, VA, NC, SC, MI, IN (part). Most brokers and shippers operate on ET. Load boards refresh first on ET.
TX, IL, MN, WI, MO, AL, MS, LA, TN, AR, OK, KS, IA, NE. Chicago and Dallas are key hubs. Difference from ET: -1 hour.
CO, AZ, NM, UT, MT, WY, ID. Arizona does NOT observe daylight saving time (except the Navajo Nation). Difference from ET: -2 hours.
CA, WA, OR, NV. The ports of LA/Long Beach operate on PT. When it's 8:00 AM in NY โ it's only 5:00 AM in LA. Difference from ET: -3 hours.
Freight in the US depends heavily on the season. Produce season, holiday season, harvest โ all of it affects rates, load availability, and road conditions. An experienced dispatcher plans routes with seasonal patterns in mind and earns more. Switch the tabs to see the details for each season.
Spring is the start of produce season. Florida and California begin large-scale shipments of fruits and vegetables to the north and east. Reefer truck rates rise by 20-40%. Construction season kicks off in the northern states โ demand for flatbed increases. This is one of the best periods to earn.
Peak produce season. California ships maximum volumes. Construction is in full swing across the country. But the heat creates problems: reefer equipment runs at its limit, drivers tire faster, and tires blow more often on the hot asphalt. Hurricane season starts in June โ the Gulf Coast is at risk.
Fall is the most profitable period in freight. Harvest season in the Midwest (grain, corn, soybeans), holiday season (getting ready for Black Friday and Christmas), and produce out of CA continues. Rates hit their yearly peak in October-November. This is the time when a dispatcher can earn the most.
Winter is a tough period. Holiday season continues into December, but after New Year's comes the "January slump" โ the slowest month of the year. Rates drop by 20-30%. Snowstorms and ice in the northern states cause delays and dangerous conditions. But Florida produce starts in January, and emergency freight from winter storms can be very profitable.

Deadhead (empty miles) is the number-one enemy of profitability. Every mile without a load is fuel cost, wear, and the driver's time with no income. The average cost of a deadhead mile is $1.50โ$2.00 (fuel + wear & tear). If a driver runs 200 miles empty โ that's $300โ$400 in losses. An experienced dispatcher minimizes deadhead through strategic backhaul (return load) planning. Here are proven strategies:
Before you take a load to a certain point, check whether there are return loads out of that region. Use DAT, Truckstop.com, or Convoy to search. If there are few loads out of the delivery point โ either pass on the load, or build the deadhead into the rate of the current load.
Instead of one long route, plan a chain of 2-3 short loads. This minimizes deadhead and increases the total RPM. Each next pickup should be within 50-100 miles of the previous delivery.
Every region has directions with high demand (headhaul) and low demand (backhaul). Outbound from CA, FL, TX is usually headhaul with high rates. Inbound to these states is backhaul. Use DAT RateView to analyze rates by lane.
Produce season (spring-summer) creates headhaul out of FL and CA. Holiday season (fall) โ headhaul out of ports and distribution centers. Harvest (fall) โ headhaul out of the Midwest. Plan your drivers' routes with seasonal freight flows in mind.
In deadhead zones (Arizona, Montana, Maine), loads rarely show up on the boards. But local brokers have regular shippers. Build relationships with 2-3 brokers in each problem zone โ they'll give you loads that aren't on DAT.
If a direct backhaul isn't possible โ build a triangular route. Instead of AโBโA (where BโA is deadhead), plan AโBโCโA, where every leg has a load. This takes more planning, but it significantly increases income.
Deadhead is empty miles without a load. Some regions are known for being hard to find a return load out of. A dispatcher must know these zones and plan routes so as to minimize deadhead miles. Every empty mile is lost money.
One of the worst regions for a return load. After delivering to Phoenix or Tucson, a driver is often forced to run 200-400 miles empty to the next load. Little industry, little population, few warehouses.
High riskOutside of harvest season โ practically a desert for freight. Distances between cities of 100-300 miles, few loads. In harvest season the situation changes, but the window is short (2-3 months).
High riskThe far northeast โ little industry, little population. After delivering to Bangor or Burlington, a return load is hard to find. In winter the situation is even worse because of the weather.
Medium riskMountainous terrain with limited infrastructure. Narrow roads, few large warehouses and distribution centers. The coal industry is shrinking โ there is less freight.
Medium riskBetween El Paso and San Antonio โ 550 miles with a minimum of freight. I-10 through West Texas is one of the longest deadhead stretches. Cross-border freight out of Juarez helps, but isn't always available.
High riskOutside of Portland and Seattle โ few loads. Agricultural areas are active only in season. In winter, mountain passes can be closed, which further limits the options.
Medium riskBefore you send a driver on a route, run through this checklist. Each item expands with a detailed explanation โ click to see the details.
Use PC Miler (the industry standard) or Google Maps to calculate. Keep in mind that truck routing differs from car routing โ not every road is open to trucks. Add 10-15% to the calculated time for unforeseen delays, fueling, and rest.
Hours of Service: a driver can drive a maximum of 11 hours after 10 hours of rest. A 14-hour window from the start of the workday. A mandatory 30-minute break after 8 hours. A 70-hour limit over 8 days. Check the driver's ELD before booking a load.
Pickup and delivery times are always given in local time. If a load runs from Chicago (CT) to New York (ET) with delivery at 8:00 AM ET โ the driver must plan on Eastern Time. A time-zone mistake = being late = a penalty or a lost load.
In winter: check for snowstorms, ice, pass closures. In summer: tornadoes in Tornado Alley, hurricanes on the Gulf Coast, heat in the Southwest. Use weather.gov and 511 traffic info. Warn the driver ahead of time and have a plan B.
RPM (Rate Per Mile) = total rate รท total miles (including deadhead). The minimum acceptable RPM depends on the region and equipment type, but is usually $2.00+. Account for tolls, fuel surcharge, and detention pay. Don't forget the deadhead miles to pickup.
Before sending the driver, check for loads out of the delivery point back or in the direction you need. Use DAT, Truckstop, Convoy to search. If there are few loads out of the delivery region (a deadhead zone) โ factor that into the rate of the current load. Better to take a bit cheaper but with a guaranteed backhaul.
Maximum weight: 80,000 lbs (gross). But some states have bridge formula restrictions. Overweight permits are needed for loads over the limit. Oversize loads (wide, tall, long) require special permits and sometimes escort vehicles. Check the requirements of each state on the route.
Toll roads can cost $50-$200+ for a truck on a single route (NJ Turnpike, Ohio Turnpike, Illinois Tollway). Some shippers reimburse tolls, others don't. Confirm ahead of time. EZ-Pass / PrePass save time and money. Factor tolls into the route's profitability calculation.
