CDL General Knowledge TestTransporting Cargo SafelyMedium
When transporting a load that extends more than 4 feet beyond the rear of the vehicle during daylight hours, what is the minimum marking requirement?
- AA red flag at least 12 inches square.
- BTwo red flags at least 18 inches square.
- CReflective tape along the entire overhang.
- DA red light visible from 500 feet.
Show answer & explanationAnswer & explanation
Correct answer: A. A red flag at least 12 inches square.
Federal regulations (specifically FMCSA 393.11) state that loads extending 4 feet or more beyond the rear of the vehicle must have a red flag, at least 12 inches square, on the extreme end of the load during daylight hours. At night or during times of poor visibility, red lights are required.
Why the other options are wrong
- B. While more flags might be used, 18 inches square is not the minimum specified, and two are not explicitly required for the minimum marking.
- C. Reflective tape is a good safety measure but not the primary or minimum marking requirement for daylight overhangs.
- D. Red lights are required for night-time or poor visibility, not daylight.
Overhang Markings (Daylight)
Visual indicators required for loads extending beyond the vehicle's rear during daylight hours to alert other drivers.
- Required for overhangs 4 feet or more.
- Must be a red flag, at least 12 inches square.
- Placed at the extreme end of the load.
Memory trick: Daylight needs a flag, night needs a light.
