Step-by-step explanation:
If the trailer or motor vehicle is transporting logs, long pulpwood, poles, or post that extends more than four feet beyond the rear of the load, you must be cautious and take certain measures to ensure safety on the road. As per road regulations, you should have a red flag, red lights, or red reflectors attached to the end of the extending load.
