What does a sign with a motorcycle symbol indicate?

A sign with a motorcycle symbol indicates that drivers should be especially aware of motorcycles on the road. This warning helps to remind motorists that motorcycles may be present and that they often require more attention due to their smaller size and different handling characteristics compared to larger vehicles.

Motorcycles can be more difficult to see, especially in blind spots, and may also maneuver differently in traffic. Thus, this sign plays a critical role in enhancing safety for both motorcyclists and other road users by promoting vigilance and caution.

The other options do not capture the primary function of the sign. For instance, yielding to motorcycles is a crucial behavior, but the sign specifically aims to alert drivers to their presence rather than dictate yielding. Similarly, it does not indicate a specific lane for mopeds or an area designated for motorcycle-only parking; these would be indicated by different signs with specific symbols or wording.
