Which of the following is NOT an exception to a common carrier's liability?

The correct answer identifies loss due to negligence of the carrier as not an exception to a common carrier's liability. Common carriers are held to a high standard of care, meaning they are typically responsible for any loss or damage to the goods they transport, regardless of the cause. This liability can only be diminished under specific exceptions that are accepted in legal terms.

Loss due to negligence of the carrier does not qualify as an exception because if the carrier is negligent, they would still be liable for damages or losses incurred. This principle underscores the duty of care required of common carriers in providing transport services.

In contrast, the other choices – acts of nature, fault of the shipper, and inherent vice – are recognized exceptions to this liability. Acts of nature refer to unforeseen events, such as severe weather, that could cause damage or loss, while fault of the shipper involves issues directly attributable to the instructions or the condition of the goods provided by the shipper. Inherent vice pertains to the natural characteristics of certain goods that may lead to their deterioration or damage during transport, making the common carrier not liable for such losses.

Thus, identifying loss due to the carrier's negligence as not an exception accurately aligns with the legal framework governing the responsibilities of common carriers.
