Roadcheck Week Is a Freight Timing Weapon. Use It.

Every May, the Commercial Vehicle Safety Alliance runs International Roadcheck. Three days. Inspectors at scale across North America. Drivers with out-of-service violations get pulled immediately. Trucks with marginal equipment don't move. Capacity tightens. Spot rates spike. And most brands watch their transit SLAs slip while wondering what happened. You already know the date. That's your edge.

Who Loses During Roadcheck

Small carriers take the hardest hit. Their fleets skew older. Maintenance compliance is inconsistent. Roadcheck puts those trucks off the road for the duration. That removes capacity from the spot market at exactly the moment shippers need it most. Larger contracted fleets weather it better. But even they throttle scheduling around the inspection window. If your replenishment cycle lands inside those 72 hours, your DC receives late. Your in-stock rate drops. Your sell-through on high-velocity SKUs takes the hit. The out-of-stock shows up in your NetPPM report a week later, and you're already behind.

The Predictability Is the Point

Roadcheck is announced months in advance. The CVSA publishes it. FreightWaves covers it. Every major carrier knows it is coming. And yet most e-commerce brands treat it like a surprise. They do not pre-position. They do not adjust PO timing. They run their standard replenishment cadence straight into a capacity wall. This is not a supply chain crisis. It is a calendar failure. The brands that win are running a different playbook. They pull POs forward by four to five days. They stage high-turn SKUs at forward DCs before the blitz opens. They lock contracted capacity before spot rates climb. By the time Tuesday of Roadcheck Week arrives, their freight is already moving or already landed.

What the Top Decile Does Differently

Top-decile operators treat Roadcheck as a recurring inventory event, not a freight problem. The distinction matters. A freight problem gets handed to your 3PL. An inventory event gets managed by your commerce team. Pull your velocity data now. Identify which ASINs have fewer than seven days of forward cover at your primary FC. Those are your Roadcheck exposure SKUs. Calculate landed cost on expedited pre-positioning against the cost of a stockout during a peak velocity window. The math almost always favors pre-positioning. A missed sale on a top-20 ASIN costs more than an incremental fuel surcharge.

Your Move Before Next Roadcheck

Add Roadcheck Week to your annual fulfillment calendar today. Mark it as a restricted replenishment window, identical to how you'd flag a peak carrier blackout. Build a standing SOP: POs for high-velocity SKUs ship no later than five days before Roadcheck opens. Contracted capacity gets locked by April 30 for the following May window. Your SP-API inventory feeds should flag any ASIN dropping below ten days of cover in the two weeks prior. This is not a complex system change. It is a calendar discipline. One cohort of brands knows this. The rest are paying spot premiums and filing carrier claims after the fact.

Three Questions to Pressure-Test Your Readiness

Does your replenishment calendar block Roadcheck Week as a restricted ship window, or does it treat every week in May identically? Which five ASINs by unit velocity would cost you the most revenue if they went out of stock for 72 hours — and where does their forward cover sit right now? If your primary contracted carrier pulls capacity during an inspection blitz, what is your named fallback and what is the landed cost delta to activate it? Answer those three. Then set the calendar block.
