Dunnage in trucking refers to low-cost materials like wood blocks, pallets, plastic wraps, air bags, or foam used to secure and protect cargo during transport. It acts as a buffer to prevent shifting, rubbing, or damage from vibrations and road bumps, ensuring loads arrive intact—especially vital for flatbed, dry van, or reefer trailers.

Core Purpose

Dunnage stabilizes freight by filling voids, elevating items off the trailer deck (often 2-6 inches for forklift access), and cushioning against impacts.

In open-deck hauls, it separates cargo from the floor and each other, reducing wear and enabling side-loading.

Shippers rely on it to maximize truck space efficiency while minimizing claims for damaged goods.

Common Types

Here's a breakdown of popular dunnage options in trucking:

Type| Description| Best For| Pros| Cons
---|---|---|---|---
Wood (blocks/pallets)| Scrap lumber or 4x4s placed under/around loads 13| Flatbeds, heavy machinery| Cheap, strong, reusable| Splinters, weight adds up
Plastic/foam| Sheets, wraps, or interlocking racks 47| Fragile electronics, pallets| Lightweight, clean| Less durable for heavies
Air bags| Inflatable pillows filling gaps 8| Container vans, voids| Custom fit, reusable| Punctures easily
Bubble wrap/paper| Cushioning fillers 1| Small parcels, e-boxes| Inexpensive, flexible| Compresses over distance

Wood dominates trucking due to availability at yards, but eco-shifts favor recyclables amid 2026 supply chain talks.

Real-World Trucking Story

Picture this: A Midwest shipper loads steel pipes on a flatbed without enough wood dunnage. Midway, curves cause shifting—tires blow, pipes dent, and the driver files a $10K claim.

With proper 2x4 stacks elevating and chocking the load, straps hold firm; delivery's smooth, profits stay put.
One carrier shared online: "Forgot dunnage once—never again. It's the unsung hero of zero-damage runs." (Echoing forums where drivers vent about "dunnage shortages" costing hours.)

Why It Matters Now (March 2026)

Fuel costs up 15% post-2025 regs make efficient loading key—dunnage cuts waste by packing tighter.

Trending carrier forums buzz with tips: Pair it with edge protectors for hazmat hauls or auto parts.

Regulators like NHVR stress it boosts lashings and friction, slashing accident risks.

Quick Tips from Pros

  • Stock up : Carriers often BYO, but confirm via BOL to avoid delays.
  • Measure twice : Calculate voids pre-load; overpack beats underuse.
  1. Inspect trailer deck for sharp edges.
  2. Layer dunnage: Base elevation, mid-fillers, top-cushion.
  3. Secure with straps/chains over it all.

Multi-view: Shippers love cost (pennies per load); drivers hate hauling extras; receivers praise pristine arrivals.

TL;DR : Dunnage = cheap cargo armor in trucking—wood/plastic buffers that prevent shifts, protect goods, and streamline ops. Skip it, risk ruins.
