危险货物

HAZMAT 证照使司机能够在发生事故时运送被认为对周围环境或更广泛环境比其他环境更危险的材料。 HAZMAT 货物分为三层，每层依次需要单独的证照。

In order to take delivery orders involving HAZMAT cargo, you need an appropriate license . There are three tiers of HAZMAT licenses, each granting access to increasingly more dangerous cargo:

• Tier 1 - Flammable , asphyxiating and oxidizing materials
• Tier 2 - Explosive , corrosive and toxic materials
• Tier 3 - Biohazardous and radioactive materials

HAZMAT licenses need to be acquired successively, and require you to already own the Fragile license, which allows transporting cargo that is highly sensitive to collisions .
