Reefer pays more than dry van, but it also punishes mistakes that dry van forgives — a blown setpoint or a missing temp log can cost you the load and the relationship. Here is where refrigerated freight actually comes from, what it should pay, and the food-safety paperwork that trips up carriers switching over.

A dry van driver who shows up two hours late is an inconvenience. A reefer driver who shows up two hours late with produce sitting at the wrong pulp temperature is a rejected load, a claim, and possibly a phone call to a food safety auditor. That's the trade carriers make when they move into refrigerated freight — real rate premiums in exchange for real consequences when something goes wrong.
It's worth it for the carriers who understand what they're actually being paid for. This guide covers what reefer freight pays right now, where the loads come from, the temperature and documentation details that separate reliable reefer carriers from the ones shippers stop calling, and the seasonal patterns that make or break a lane.
Quick answer: reefer loads come from equipment-specific load boards, brokers who specialize in produce and cold chain freight, and direct relationships with distribution centers and food processors. Rates typically run $0.15–$0.40 per mile above dry van on comparable lanes, with pharmaceutical freight paying the most. The details that matter most — temperature range, pulp vs. air temp requirements, and FSMA documentation — are things dry van carriers never had to think about, and getting them wrong costs you the account, not just the load.
New reefer operators often think of the equipment as a single category — "cold" versus "not cold." Shippers don't see it that way, and neither should you:
The equipment might look the same from the outside, but the tolerance for error shrinks as you move from produce toward pharma. Know which category a load falls into before you bid — the setpoint on the load posting only tells you the target, not how much room you have for error.
This is the single most common misunderstanding among carriers switching into reefer. Your reefer unit controls the air temperature inside the trailer — but produce shippers often care about pulp temperature, the actual internal temperature of the product itself, which can lag well behind the air temperature for hours after loading.
A trailer that shows the correct air temperature on the reefer unit's display can still be hauling produce that was loaded warm and hasn't cooled through yet. Reputable shippers precool their product before loading and expect carriers to precool the trailer before arrival — running the reefer unit for 30–60 minutes to bring the box down to setpoint before the doors open at the dock. Skipping this step is one of the most common causes of rejected loads, and it's entirely on the carrier to get right.
If a shipper hands you a pulp temperature probe at pickup, that's not a formality — check it, note the reading, and don't sign for freight that's already out of range before you've pulled away from the dock.
Reefer rates move with produce season, fuel, and lane, but current market ranges look roughly like this:
The premium over dry van exists because fewer carriers can run the equipment reliably, and because the cost of failure is higher for the shipper — a spoiled truckload of berries is a total loss, not a late delivery. Carriers who consistently protect product quality get first access to a shipper's next load, often before it's posted anywhere.
Generalist load boards frequently treat reefer as a checkbox rather than a filtering category, which means you're stuck scrolling past dry van freight to find the small percentage that fits your trailer. FreightBidder's reefer load board filters by equipment and required temperature range from the start — frozen, fresh/chilled, or pharmaceutical-grade — so what you see is what your trailer can actually haul.
Produce and cold chain freight has its own broker ecosystem, separate from general freight brokerage. These brokers understand seasonal harvest timing, precooling requirements, and the claims process for temperature excursions — details a generalist broker often gets wrong. Building two or three relationships with cold chain-specialized brokers gives you access to consistent seasonal volume without having to chase every shipper directly.
Grocery distribution centers, food processors, and cold storage warehouses move recurring freight on predictable schedules — restocking runs, processor-to-DC lanes, and DC-to-DC transfers. These relationships take longer to build than a load board bid, but they produce the steadiest reefer volume available, because the shipper needs the same lane covered every week, not just once.
The FDA's Sanitary Transportation Rule, part of the Food Safety Modernization Act, applies directly to carriers hauling food freight — and most new reefer operators have never heard of it. In practice, it requires:
Shippers that take food safety seriously will ask about your temperature recording setup before they award you a load — a simple onboard data logger or a reefer unit with recording capability is enough to satisfy most requirements, but "I checked it a few times on the drive" is not. This isn't a box-checking exercise for compliance's sake. It's the paperwork that gets you re-booked after a claim dispute, because you can prove the trailer held setpoint the whole way.
Reefer freight follows the harvest calendar in a way dry van freight doesn't. California's Central Valley runs heavy produce volume from spring through fall. Florida and South Texas produce peaks run roughly December through April, driven by citrus and winter vegetables. The Pacific Northwest ships berries, apples, and seafood on its own seasonal rhythm. Knowing these calendars ahead of time lets you position your equipment where the freight actually is instead of reacting to a thin board.
The harder problem is backhauls. A lot of high-volume produce lanes run heavy in one direction and empty in the other — freight moves from growing regions to population centers, but there's no equivalent volume of reefer freight moving back. Carriers who don't plan for this end up running an expensive deadhead leg back to their next pickup, which quietly erodes the rate premium reefer is supposed to deliver.

The carriers who do this well build a mental map of secondary freight — frozen goods, grocery distribution, or dry-storable freight that can move opposite a produce lane — so the return leg isn't dead weight. Lane alerts help here too: setting alerts on both legs of a corridor, not just the outbound one, surfaces backhaul freight before you're sitting empty at a delivery dock deciding where to go next.
Most reefer trailers run a single temperature zone, which is simpler to operate and maintain but limits you to one freight category per load. Multi-temp trailers use internal bulkheads to run two or three separate zones at different setpoints — useful for combining frozen and chilled freight on the same run, but they cost more upfront and require more careful load planning to avoid one zone's airflow interfering with another.
Reefer units themselves are a real cost center that dry van operators don't have to budget for. Fuel or electric standby costs, routine maintenance on the compressor and condenser, and periodic unit replacement (most reefer units run 5–7 years before major overhaul or replacement) all factor into what a load actually needs to pay to be worth taking. When you're comparing a reefer rate to a dry van rate on the same lane, remember you're not just comparing driver pay and fuel — you're covering a second engine's worth of fuel and maintenance too.
Beyond the FSMA temperature records, shippers moving high-value or regulated freight typically expect:
Carriers who provide this documentation without being asked twice tend to get repeat business fast. It signals that you understand the freight is perishable and behave accordingly — which, on cold chain lanes, is worth more to a shipper than a slightly lower rate from a carrier they're not sure about.
FreightBidder's reefer load board filters loads by temperature range and equipment type from day one, so you're not digging through dry van postings to find what fits your trailer. Every reefer load shows the required setpoint, product category, and any special handling notes before you bid.
Create a free account, complete FMCSA verification, and set your equipment as refrigerated or temperature-controlled. The free plan includes 10 bids a month with full board access; Carrier Pro adds unlimited bids, an AI rate advisor tuned to current cold chain pricing, and lane alerts for the produce corridors and seasons you actually run — including backhaul lanes, not just outbound ones.
