What action must be taken when hazardous materials are discovered in a passenger's possession?

When hazardous materials are discovered in a passenger's possession, the appropriate action is to not allow the rider to get on. This stems from safety regulations and protocols designed to protect both passengers and the driver. Hazardous materials can pose significant risks, such as fire, explosion, or poisoning, and transporting them in a passenger vehicle would not only violate legal regulations but could also endanger everyone on board.

It is critical for drivers and transport services to maintain a safe environment, which includes taking proactive measures to exclude anyone carrying hazardous substances from boarding the vehicle. This ensures compliance with safety standards and regulatory requirements, as well as prioritizes the well-being of all passengers.

Allowing the passenger to keep hazardous materials, store them in the luggage compartment, or transport them while informing authorities does not adequately address the immediate danger and could lead to serious safety hazards during transportation. Therefore, the most responsible action is to prevent the passenger from boarding the vehicle.
