Commercial Driver's License

Answer: A - If transporting a load that extends 48 inches or more from the rear of the trailer, drivers must ensure that a solid red or fluorescent orange flag of at least 12 inches square is attached to the extreme end of the load. This flag helps other drivers to see the end of the load and can prevent very serious accidents from happening. The flag size and color requirements may vary from state to state, so drivers should find out what the requirements are for each state they plan to travel through.
