Arkansas Boating Practice Exam

What do red and green lights on a vessel indicate?

1. Port and starboard sides, respectively

2. Stern and bow, respectively

3. Emergency status

4. Mechanical failure

The correct answer is: Port and starboard sides, respectively

Red and green lights on a vessel do not indicate both stern and bow sides. This is incorrect because the red light is only used to indicate the port (left) side of the vessel, and the green light is only used to indicate the starboard (right) side of the vessel. Additionally, the option stating that these lights indicate emergency status is also incorrect as emergency lights are typically not red and green. The option mentioning mechanical failure is also not correct as these lights are not used to indicate any problems with the vessel. Therefore, the only correct answer is A, where red and green lights are used to indicate port and starboard sides, respectively.
