Los Angeles and Inland Empire Truck Dispatch

The Los Angeles basin is the front door for goods from Asia. The ports of Los Angeles and Long Beach sit side by side on San Pedro Bay, and the containers they unload fill warehouses from the harbor to the high desert. For a truck, the story is simple: freight leaving Southern California is plentiful and pays well, while freight coming back in is harder to find.

Most over-the-road owner-operators never touch the port terminals. They load in the Inland Empire, the warehouse region east of Los Angeles, and head out on I-10, I-15 or I-40.

Two ports, one harbor

The Port of Long Beach reports that it moved 7,675,255 TEUs through September 2026, and that September was its busiest month on record. The Port of Los Angeles next door handles a similar amount. A TEU is one 20-foot container; most boxes are 40 feet, or two TEUs.

Containers leave the terminals three ways. Some go on trains straight to Chicago, Dallas and Memphis. Some go to transload warehouses near the harbor, where the goods are moved into 53-foot trailers. Most of the rest go by drayage truck to warehouses inland. That second and third step is where long-haul loads come from.

The freight map of Southern California

Driving the basin

• Traffic sets the schedule. I-10, SR-60, I-605 and I-710 back up for hours. Many shippers in the Inland Empire load at night or early morning, and those are the easiest runs to make on time.
• The Cajon Pass is steep. I-15 climbs a long, steep grade from San Bernardino to the high desert. Strong winds can close it to high-profile trucks, and winter storms bring chain controls.
• Parking is scarce. Truck parking near the ports and in the Inland Empire fills early. Plan where you'll take your 10-hour break before you start.
• State rules apply. California's 55 mph truck speed limit and CARB's Clean Truck Check apply in every part of the basin. The state page linked below covers them.
• Port terminals have their own rules. Drayage trucks need registration and terminal appointments to enter. The San Pedro Bay Ports Clean Air Action Plan sets the truck standards for both ports.

Outbound lanes and the trip back

The outbound side is easy. The challenge is getting back. A good plan books freight heading toward California before you deliver at the far end: Arizona and Central Valley produce, Texas freight to the West Coast, or a short run from Phoenix. Our guide to cutting deadhead explains the thinking.

Transload warehouses

Many imports never reach the Inland Empire in their original container. Near the harbor, transload warehouses open the 40-foot ocean boxes and repack the goods into 53-foot trailers, which hold more. Those trailers are often ready to go long distance the same day. Transload loads tend to be heavy and mixed, so ask about weight and pallet count, and expect a tight pickup window.

Equipment that fits

• Dry van: the core of Inland Empire freight, from furniture to electronics.
• Power only: trailer pools at the big distribution centers.
• Reefer: food plants in Commerce and Vernon, and produce from inland valleys.
• Box truck: metro delivery work, if the truck meets California rules.

Seasons in Southern California

• Late summer to fall: Peak import season for the holidays. Warehouses run hard, and outbound volume is at its highest.
• Fall: Santa Ana winds, which can close the Cajon Pass and other routes to high-profile trucks, and wildfire closures in some years.
• Winter: Snow and chain controls on the Cajon Pass and the Grapevine on I-5.
• After Lunar New Year: Imports often dip for a few weeks while factories in Asia restart.

Southern California checklist: CARB, 55 mph and the passes

• Make sure your truck is current on Clean Truck Check before you enter the state.
• Plan the run at 55 mph, and add time for traffic in the basin.
• Check winds and closures on the Cajon Pass and the Grapevine.
• Line up the reload back toward California before you deliver out of state.
• Find truck parking for your 10-hour break before you start the day.

Booking Southern California freight with us

Your dispatcher books loads out of the Inland Empire and the harbor area, checks your Clean Truck Check status first, and plans the trip back before the trip out.

Statewide rules, from the MCP to chain controls, are on our California dispatch page. The usual next stops are Arizona on I-10 and Utah on I-15. Long runs east add up, so check them with the load profit calculator first.
