The Bill of Lading Shield: How Dock Stamps and Exceptions Exonerate Motor Carriers

How shipper load count exceptions, seal numbers, and dock supervisor in/out timestamps protect motor carriers from freight loss and dock detention disputes.

In freight transportation law, the Bill of Lading (BOL) is three legal instruments in one: a receipt of goods, a document of title, and a legally binding contract of carriage under the Carmack Amendment (49 U.S.C. ยง 14706). Yet many drivers treat the paper BOL as a simple formality, leaving themselves completely exposed to freight claims.

1. The Critical "SLC" Protective Notation

When a shipper loads a sealed trailer without the driver physically counting cartons, the driver must explicitly write: "Shipper Load & Count" (SLC) or "Said to Contain" (STC) next to their signature. Under federal law, this notation legally shifts the burden of proof back to the shipper for missing inventory upon delivery, neutralizing broker claims for short pallet counts.

2. Exact Tamper-Evident Seal Verification

High-security bolt seals must be matched character-for-character between the physical door bolt and the typed BOL document before leaving the facility gate. If a shipper writes "SEAL 89420" on the paperwork, but hands the driver a bolt stamped "SEAL 89421", that single discrepancy permits the consignee to reject the entire trailer load for suspected contamination.

3. Exact In/Out Timestamps for Detention

Brokers universally deny accessorial detention claims unless the receiver physically stamps the Arrival Time and Departure Time on the signed delivery receipt. When your truck arrives at a facility, ensure the guard shack or check-in clerk writes down your exact arrival time immediately.

Frequently Asked Questions

What does SLC mean on a commercial Bill of Lading?
SLC stands for Shipper Load and Count. It indicates that the shipper loaded the trailer without driver inspection, legally shielding the carrier from short pallet claims.
Why will brokers deny detention claims without a stamped BOL?
Brokers require verifiable third-party facility evidence of arrival and departure timestamps to bill detention back to the primary shipper.
