Adım Adım Çözüm

1
Identify the mandatory emergency equipment categories required on commercial vehicles.
Every commercial motor vehicle must carry three basic emergency items: a properly rated fire extinguisher, spare electrical fuses (if applicable), and warning devices for parked vehicles.
Federal Motor Carrier Safety Regulations (49 CFR § 393.95) specify the required emergency safety devices.
2
Determine the required quantity for red reflective triangles.
When using red reflective triangles as emergency warning devices, the driver must carry a minimum of three triangles.
Three triangles are necessary to properly mark the vehicle's position when stopped on the shoulder or roadway (one placed 10 feet behind, one 100 feet behind, and one 100 or 200 feet ahead/behind depending on road configuration).
