Where must you keep the papers about hauling hazardous materials?

Firefighters and police can prevent or reduce the amount of damage or injury at the scene if they know what HazMat is being carried. Your life, and the lives of others, may depend on quickly locating the HazMat shipping papers. For that reason the rules require:
• Shippers to describe HazMat correctly and include an emergency response telephone number on shipping papers.
• Carriers and drivers to quickly identify HazMat shipping papers, or keep them on top of other shipping papers and keep the required emergency response information with the shipping papers.
• Drivers to keep HazMat shipping papers in or on:
— A pouch on the driver’s door.
— Clear view within immediate reach while the seat belt is fastened while driving.
— The driver’s seat when out of the vehicle. [California Commercial Driver Handbook]
