Dry Van Freight Rules, Load Requirements & What Brokers Need to Know
Dry van is the backbone of North American freight. Most brokers start their careers quoting dry van loads, and most never stop — it's the most available equipment type, the most carrier options, and the most common freight on the road. But "dry van" is not a single fixed spec. Dimensions vary by age of equipment, payloads vary by commodity density, and not every dry van carrier has the same dock-access capability. This guide covers the rules, specs, and planning logic you need to quote dry van loads accurately.
What Is a Dry Van Trailer?
A dry van is a fully enclosed, weathertight trailer with a solid roof, four walls, and a swing or roll-up rear door. It protects freight from rain, wind, and road debris without active temperature control. Freight is loaded from the rear and sits on the trailer floor or on pallets. Dry van is the default equipment type for general freight — if it doesn't need temperature control, open-deck loading, or oversized handling, it probably moves in a dry van.
Standard Dry Van Trailer Dimensions
The 53-foot trailer is the industry standard for long-haul dry van freight in North America. 48-foot trailers still exist — mostly on regional routes and with older private fleets — but if you're asking a carrier for a dry van without specifying length, they'll almost always send a 53.
Standard dry van trailer specifications
| Spec | 53-Foot Trailer | 48-Foot Trailer |
|---|---|---|
| Interior length | 53 ft (636 in) | 48 ft (576 in) |
| Interior width | 98–100 in (8'2"–8'4") | 98–100 in |
| Interior height | 108–110 in (9'–9'2") | 108–110 in |
| Door opening width | 94–96 in | 94–96 in |
| Door opening height | 102–106 in | 102–106 in |
| Max pallet positions | Up to 30 standard pallets | Up to 26 standard pallets |
| Typical payload | 42,000–45,000 lbs | 43,000–46,000 lbs |
Weight Limits and Legal Maximums
The U.S. federal gross vehicle weight limit is 80,000 lbs. A standard tractor-trailer combination weighs approximately 33,000–35,000 lbs empty, leaving roughly 44,000–47,000 lbs of net payload capacity. In Canada, federal limits allow up to 62,500 kg (137,788 lbs) under the National Safety Code, but provincial maximums and bridge formulas vary significantly by province and route.
U.S. federal weight limits — key axle configurations
| Axle Configuration | Maximum Legal Weight |
|---|---|
| Steer axle (single) | 20,000 lbs |
| Single drive axle | 20,000 lbs |
| Tandem drive axles | 34,000 lbs combined |
| Tandem trailer axles | 34,000 lbs combined |
| Gross vehicle weight | 80,000 lbs |
Cube vs. Weight: Which Constraint Hits First?
Every dry van load is constrained by one of two things: volume (the trailer fills up before it hits max weight) or weight (the trailer reaches its legal limit before it's physically full). Knowing which constraint applies tells you whether the carrier will be able to take an add-on stop and whether you're pricing on a per-pallet or per-pound basis.
Typical density and constraint by commodity
| Commodity | Typical Density | Usual Constraint |
|---|---|---|
| Paper products, tissue, toilet paper | 3–6 lbs/cu ft | Cube (fills trailer before weight limit) |
| Consumer packaged goods (CPG) | 8–15 lbs/cu ft | Cube or balanced |
| Beverages (canned/bottled) | 25–40 lbs/cu ft | Weight (hits 44k before filling) |
| Bottled water | 35–42 lbs/cu ft | Weight — often 20–22 pallets max |
| Building materials (drywall, flooring) | 20–35 lbs/cu ft | Weight or cube depending on orientation |
| Automotive parts (boxed) | 10–20 lbs/cu ft | Cube or balanced |
| Clothing and textiles | 2–5 lbs/cu ft | Cube (almost always) |
| Electronics (consumer) | 5–12 lbs/cu ft | Cube |
| Frozen goods (boxed, palletized) | 20–30 lbs/cu ft | Weight (also needs reefer — wrong trailer) |
A quick way to estimate: multiply the number of pallets by the average pallet weight. If 26 pallets × 1,800 lbs = 46,800 lbs and the trailer holds 30 pallets, the load is weight-constrained. The carrier can't add a stop. If 30 pallets × 800 lbs = 24,000 lbs, the trailer cubed out — weight is not the issue.
Pallet Standards and Floor Loading
Most dry van freight moves on GMA (Grocery Manufacturers Association) standard pallets: 48 inches × 40 inches. A 53-foot trailer fits two 48×40 pallets side by side (40+40 = 80 inches across the 98-inch interior), 13 rows deep, for a maximum of 26 double-stacked pallet positions — though most loads run 24–26 depending on pallet overhang.
| Pallet Type | Dimensions | Common Use |
|---|---|---|
| GMA standard | 48" × 40" | Grocery, CPG, general freight — the default |
| Half pallet | 48" × 20" | Display pallets, retail-ready shipments |
| Euro pallet (EPAL) | 47" × 31.5" | Automotive, pharmaceutical, international freight |
| Custom / oversized | Varies | Industrial, specialty — always confirm trailer fit |
Some loads are floor-loaded (no pallets) — merchandise shipped loose into the trailer and stacked from floor to ceiling. Floor loading maximizes space but requires manual unloading (lumper labor), increases damage risk, and extends unload time significantly. When quoting floor-loaded shipments, confirm lumper cost responsibility with the shipper.
Load Securement Requirements
Federal Motor Carrier Safety Administration (FMCSA) regulations (49 CFR Part 393) require that all cargo be properly secured before movement. For dry van freight, the primary securement methods are blocking and bracing built into the load configuration, and the trailer walls and bulkhead providing lateral restraint. Because most dry van freight is palletized and stacked to the walls, the securement obligation largely falls on the shipper's load plan — but the carrier is responsible for confirming the load is secure before departure.
- Palletized freight: load should be stretch-wrapped and stable before loading — no leaning stacks
- Floor-loaded freight: cross-stacked or interlocked to prevent shifting
- Loose or long items: may require straps, blocking, or a load bar across the trailer
- Fragile freight: carriers may request shippers provide blocking and bracing in writing
- High-value freight: some carriers require sealed trailers with a seal number recorded on the BOL
Dock Access and Equipment Requirements
Dry van trailers require a dock-height loading facility — the trailer door sill sits approximately 48–52 inches above the ground, which aligns with standard loading dock height. If a shipper or consignee does not have a dock, the load requires a liftgate trailer, a forklift at ground level, or drop-and-hook.
| Facility Type | What It Means | Carrier Requirement |
|---|---|---|
| Dock-high facility | Standard loading dock at 48–52" height | Standard dry van, no special equipment |
| No dock (ground-level) | Freight must be moved from ground level | Liftgate required — adds $75–$200 surcharge |
| Drop-and-hook | Carrier drops empty, picks up pre-loaded trailer | No driver wait time — preferred for high-volume lanes |
| Live load/unload | Driver waits while freight is loaded/unloaded | Detention clock starts after 2 hrs free time |
| Cross-dock | Freight transferred between trailers at a terminal | Confirm with carrier — not all accept cross-dock |
Always confirm dock access before booking. A carrier who shows up to a residential delivery expecting a dock and finds stairs will either refuse the load or charge a significant service fee. Residential delivery and limited-access surcharges from carriers range from $150 to $500+ depending on the situation.
What Dry Van Cannot Haul
Dry van is the most versatile trailer type, but it has clear limits. Knowing what it cannot handle prevents you from misquoting a load and booking the wrong equipment.
| Freight Type | Why Dry Van Won't Work | Correct Equipment |
|---|---|---|
| Temperature-sensitive goods (fresh produce, dairy, pharmaceuticals) | No temperature control | Reefer (refrigerated trailer) |
| Oversized freight exceeding interior dimensions | Cannot physically fit | Flatbed, step deck, or lowboy depending on size |
| Bulk liquids or aggregates | No containment — would leak through floor seams | Tanker or hopper |
| Live animals | Regulatory, welfare, and ventilation requirements | Livestock trailer |
| Hazardous materials (certain classes) | Placarding and separation rules may require specialized equipment | Depends on hazmat class — verify with carrier |
| Freight requiring top-loading | Dry van has no roof access | Flatbed or open-top trailer |
| Coiled steel or heavy structural steel over axle limits | Weight typically exceeds 80,000 lbs GVW | Flatbed + overweight permit, or heavy haul |
Common Dry Van Quoting Mistakes
Most mistakes on dry van loads happen during the quoting conversation with the shipper. Getting these wrong costs you either a failed load or an angry carrier.
- Not confirming actual weight — "it's a full truckload" is not a weight
- Not confirming pallet count and stackability — affects whether the carrier can take an add-on
- Assuming dock-high when the pickup is an industrial yard or residential address
- Forgetting to ask about hazmat — even one pallet of hazmat can change the carrier requirements
- Not asking about load time — a 4-hour live load means detention, which means a higher carrier rate
- Quoting based on the shipper's transit expectation without checking carrier availability for that lane
- Booking a standard dry van for frozen freight because "it's only going a few hours" — no, it still needs a reefer
Broker Checklist for Dry Van Loads
- Commodity — what exactly is moving and does it have any special handling needs?
- Weight — actual gross weight in pounds, not "a full truck"
- Pallet count and dimensions — are they GMA standard? Are they stackable?
- Dock access at origin and destination — dock-high or ground level?
- Liftgate required? — if yes, confirm the carrier has one available
- Load type — live load, drop-and-hook, or floor-loaded?
- Free time and detention policy at origin and destination
- Any hazmat? — even partial loads require carrier certification and placarding
- Seal required? — some high-value or food-grade loads require a sealed trailer with serial number
- Delivery appointment type — open, scheduled, first-come-first-served
