Detention Notice Windows: The Rate Con Clause That Kills Claims

Your driver sat six hours. The ELD proves it. The broker still says no, because nobody sent the detention notice in time. Notice clauses are the most common technicality in detention, and the easiest to beat once you know where to look.

What a notice clause looks like

It is usually one line in the accessorials section of the rate confirmation, for example:

"Detention $60/hr after 2 hrs free time. Carrier must notify broker within 24 hrs of occurrence."

Other common versions:

• Notify before free time expires
• Notify while the truck is still on site
• Notify through the broker's portal or app, not email
• Submit the detention invoice within a set number of days of delivery

Some rate cons have two deadlines: one to give notice, and another to submit the claim with paperwork. Miss either and the broker has grounds to refuse.

Why brokers enforce it

Notice gives the broker a chance to push the shipper or receiver while the truck is still waiting, and to bill their customer for it. Without timely notice, they often cannot recover the cost themselves, so they deny yours.

How to never miss one

1. Read the clause at booking. Note the deadline and the required method on the load record dispatch sees.
2. Notify early by default. Send notice when the truck is 30 minutes from the end of free time. Early notice is never a problem; late notice often is.
3. Use the required channel. If the rate con names a portal, use it, and also email so you have your own timestamped copy.
4. Keep it short. Load number, facility, arrival time, free time ending, and "truck is on detention per rate con."
5. Save the proof. Attach the timestamped notice to the claim. It answers the denial before it is raised.

A notice you can copy

Truck arrived 08:04 CT (ELD/GPS). Free time ends 10:04 CT.
Truck remains on site; detention applies per rate con #RC-88214
($60/hr after 2 hrs). We'll send the claim with documentation at departure.

Next step: file the claim the same day with the detention invoice template.
