Final answer:
You should always obey the instructions of a flagger at a road construction site as they are responsible for ensuring the safety of drivers and workers. Their directions take priority over normal traffic signals and signs.
Step-by-step explanation:
When encountering a flagger at a road construction site, you should indeed obey his or her instructions. Flagger instructions are critical for maintaining safety for both drivers and workers on the road. They have the authority to stop, slow, or guide traffic safely through the construction zone. Their directions take precedence over regular traffic signals and signs. Therefore, the correct answer is 1) Yes.
It is also important to be vigilant and to travel at the correct speed limit, especially in a construction zone where workers are present and the usual road layout may be altered. The color of your car does not impact the speed at which you are traveling, regardless of any misconceptions or myths.
