Drivers should refrain from smoking within a certain distance of placarded hazardous materials due to the fire risk associated with many hazardous substances. Smoking introduces an open flame, which can ignite flammable materials or vapors that may be present, potentially leading to explosive incidents or fires. The presence of placards indicates the nature of the hazards, and smoking in proximity to these materials severely compromises safety protocols designed to minimize the risk of accidents.

In addition to the dangers associated with smoking, there are also regulations and guidelines that explicitly prohibit smoking around hazardous materials to ensure compliance with safety standards. This precaution is critical in protecting not only the driver but also other individuals nearby and the environment from possible catastrophic events. Such measures are part of a broader focus on maintaining a safe transportation environment for hazardous materials.
