Severe weather in trucking: how dispatch prepares, reroutes and bills for it

Severe weather costs a fleet three ways: trucks that cannot move, loads that miss their windows, and detention nobody can prove. The Federal Highway Administration counts about 745,000 weather-related crashes a year, roughly 12 percent of all crashes on the 2019 to 2023 average. What a dispatcher controls is the plan: which loads roll, which wait, who tells the customer, and whether the arrival and departure times are on the load record in trucking dispatch software when the detention invoice goes out.

This post covers the five ways weather hits a trucking operation, then what dispatch does before the storm, during it and after.

Five ways severe weather hits a trucking operation

Weather costs a fleet in five places: driver safety, delays and the detention that comes with them, customers, regional differences, and the data you do not have when the storm hits.

1. Driver safety

Driver safety is critical in the trucking industry, and severe weather conditions magnify the risks faced by truckers on the road. Reduced visibility, slippery roads, icy conditions, washed out roads, and strong winds can lead to accidents. The Federal Highway Administration counts about 745,000 weather-related crashes a year across all vehicles, roughly 12 percent of crashes, on the 2019 to 2023 average. It is vital to ensure driver safety in severe conditions and it requires careful planning.

2. Delays, and the detention you cannot prove

Severe weather events like hurricanes, blizzards, and even heavy rainfall can lead to road closures, detours, and reduced speed limits, causing significant delivery delays. These delays interrupt schedules and add cost: detention hours, fuel, empty miles and the risk to temperature- or time-sensitive cargo. Detention is already the norm. ATRI found drivers detained at 39.3 percent of stops in 2023, and while 94.5 percent of fleets charge detention, fewer than half of those invoices get paid. A storm adds hours to that and takes away the paperwork that proves them. The increased delays may also mean lost revenue for shipments that are given to other providers.

3. Customers and missed windows

Weather-related delays can inevitably lead to customer dissatisfaction. Late deliveries hold up supply chains, leading to production delays, stock shortages, and frustrated customers at every point in the supply chain. Maintaining clear communication and managing expectations during severe weather events is essential for mitigating negative impacts on customer relationships.

4. The same storm hits regions differently

Weather patterns vary significantly across different regions and countries. While hurricanes may be a major concern in coastal areas of the United States, heavy snowfall and sub-zero temperatures pose challenges for truckers in Canada and similar weather can affect different areas in different ways. For example, snow in the Southern United States will have a major impact on road conditions compared to the Midwest United States, due to snow removal capabilities. Understanding the specific weather risks associated with different regions is important for effective route planning.

5. The data you do not have

Access to accurate and up-to-the-minute weather data is crucial for trucking companies to make informed decisions and adapt to changing conditions. Real-time weather updates enable dispatchers to plan routes effectively, anticipate potential delays, and communicate proactively with drivers and customers. It is important to note that up-to-the-minute weather updates do not always provide information on road conditions or closures.

Before the storm: the loads that roll and the loads that wait

Sort the board by appointment window and commodity. Loads that can deliver before the front arrives roll early; reefer and time-critical loads that cannot get a call to the customer today, not tomorrow. Put the plan on the trip in writing, so the decision to hold is the company's and not the driver's alone.

During: rerouting, check calls and the driver app

Dispatch needs every truck's position from the ELD, every load's appointment window and the driver's phone in one place. Fleet Manager shows truck positions from your telematics provider on the dispatch board through the telematics integration, and TransPlus Connect carries the reroute to the driver as a message on the trip, so the office is not working from a texting thread. A driver who is told to stop should stop; the load record should show who said so and when.

After: billing detention and layover with timestamps

Every hour a truck sat at a closed receiver is billable only if the arrival and departure times are on the load. When the driver updates status at each stop in the app and the position data confirms it, the detention invoice carries its own evidence. Send it with the POD, the same day.

When the storm is over, the loads that ran and the hours they sat should already be on the record. See how trucking dispatch software keeps positions, statuses and timestamps on one load, or book a demo: personalized, scheduled the same week you ask, no commitment.

Severe weather questions dispatchers ask

Can a TMS see the weather?

No. A TMS holds the loads, the trucks and the drivers; the forecast comes from the weather service and road closures from the state or provincial transportation department. What the TMS does is put every truck's position and every load's appointment window beside that forecast, so dispatch can decide which loads roll and which wait, and record the decision on the trip.

How do I prove weather detention?

With arrival and departure timestamps on the load record, confirmed by the driver's status update in the app and by the position data from the ELD, and sent with the POD. ATRI found that fewer than half of detention invoices get paid; the ones that do are the ones with the times on the record rather than in a driver's memory.

Should a driver refuse to run in a storm?

When the driver judges the road unsafe, yes. US rules require extreme caution in hazardous conditions and say the trip stops when conditions become sufficiently dangerous under FMCSA rule 49 CFR 392.14, and a carrier that pushes a driver past that owns the outcome. Put the hold on the trip record so the decision is documented, tell the customer, and reschedule off the board rather than off a phone call.
