In what case might jail time be a consequence of not following TDG?

Jail time can be a consequence of transporting dangerous goods when non-compliance results in injury. This reflects the severity with which regulatory bodies treat the mishandling of hazardous materials, especially when such actions pose a direct risk to public safety or health. The regulations governing the transportation of dangerous goods are designed to protect everyone, including workers involved in the transportation process and the general public. When negligence leads to injury, the legal framework often sees this as a significant violation that warrants serious penalties, including imprisonment.

This is in contrast to other scenarios, such as minor violations or repeated small infractions, which typically incur fines or administrative penalties rather than prison time. Severe environmental breaches could also lead to serious consequences but often involve fines or restitution to repair environmental damage—criminal charges leading to jail time are more directly connected to cases where injury to individuals occurs as a result of non-compliance.
