What does a sign meaning vehicles may pass either side indicate?

The sign indicating that vehicles may pass either side communicates that drivers have the option to overtake vehicles from either the left or the right. This is particularly important in situations where the road conditions allow for safe passing on both sides, providing flexibility to drivers when they need to maneuver around slower vehicles. It enhances traffic flow by permitting overtaking in both directions, depending on the specific situation and safety.

In contrast, other options imply more restrictive overtaking conditions, such as limiting passing to only one side or prohibiting it altogether, which doesn't align with the meaning of the sign. Understanding this sign is crucial for safe driving practices and awareness of road rules in the Cayman Islands.
