Canadian Boating Exam Practice Quiz

It is important for a flashing light to provide visible coverage in all directions. Option A, 90 degrees, would not provide enough range for visibility, as it only covers a quarter of a full circle. Option B, 360 degrees, would be excessive as a flashing light does not need to cover directly above or below it. Option D, 225 degrees, is also not the minimum as it would leave a blind spot. Therefore, option C, 180 degrees, is the most suitable and commonly used option for the effective and efficient coverage of a flashing light.
