Commercial motor vehicles must carry specific emergency equipment compliant with federal safety standards. Match each operational condition or equipment category on the left with its required emergency equipment specification on the right. Which pairings correctly associate each category with its mandated specification?
- Power unit hauling placarded hazardous materialsAt least one properly charged and securely mounted fire extinguisher rated 10 B:C or more
- Power unit hauling non-hazardous general freightAt least one properly charged and securely mounted fire extinguisher rated 5 B:C or more (or two rated 4 B:C)
- Warning devices for a stopped or disabled vehicleThree bidirectional red reflective triangles in a protective carrier
- Electrical system protection for vehicles without automatic circuit breakersAt least one spare fuse of each type and rating required to operate all vital vehicle electrical accessories
Answer
The correct pairings match hazardous materials transport with a 10 B:C fire extinguisher, non-hazardous general freight transport with a 5 B:C fire extinguisher (or two 4 B:C extinguishers), stopped vehicle warning devices with three bidirectional red reflective triangles, and electrical protection on fuse-equipped vehicles with spare fuses for each type and rating needed.
Federal safety regulations (49 CFR § 393.95) specify that all commercial motor vehicles must carry three mandatory pieces of emergency equipment: a properly rated fire extinguisher (5 B:C for general freight, 10 B:C for placarded hazardous materials), three bidirectional red reflective warning triangles, and spare electrical fuses for each required type and rating if the vehicle does not use circuit breakers.
