The ValueJet example was for improper shipping and yes a worse case. Shipping by ground does not change the risk from primers for improper shipping. DOT has increased penalties and doesn't include criminal aspects for property damage, injury or worse fatality. So if improper shopping destroys a semi owned by a blue collar worker. Or worse. Destroy a shipping terminal or worse. Yep not ValueJet.
$84,425 per day, per violation is the new maximum civil penalty for a typical hazmat shipping violation.
$196,992 per day, per violation is the new maximum civil penalty for a violation that results in death, serious illness, severe injury, or substantial property damage.
Now understand the per day per violation can be applied to the actual number of articles in the shipment.
