Is a driver ever required to place placards on a vehicle hauling hazardous materials?

When it comes to the transportation of hazardous materials, there are specific requirements regarding the use of placards. Placards are visual signs that help indicate the presence of hazardous materials in transport, promoting safety for those handling, transporting, or encountering such materials. However, not all transportation of hazardous materials necessitates the use of placards.

There are certain scenarios where placarding is required, primarily depending on the type and quantity of hazardous materials being transported. For instance, if a driver is transporting over a specific threshold quantity of hazardous materials or certain classifications, they are required to display the appropriate placards. On the other hand, if a vehicle is transporting hazardous materials below those required thresholds or specific hazardous materials that do not warrant placards, then placarding is not necessary.

This understanding emphasizes that the use of placards is conditional, and therefore, stating that a driver is never required to place placards is not entirely accurate. Placarding does have its criteria based on the nature and amount of dangerous goods being transported, which means there could very well be instances where placards are necessary. The assertion that a driver is never required to place placards overlooks these critical factors in hazardous material transport regulations.
