The "No overtaking" traffic sign indicates that vehicles are prohibited from passing each other on that portion of the roadway. This sign is implemented to enhance safety, particularly in areas where passing might be dangerous due to traffic conditions, road geometry, or visibility concerns. By prohibiting overtaking, the sign helps to reduce the risk of accidents that can occur when vehicles attempt to pass in areas where it is not safe to do so. The design of such signs aims to clearly inform drivers of restrictions that are in place for their protection and the safety of all road users.

The other options do not accurately reflect the implications of a "No overtaking" traffic sign. For instance, stating that only buses can overtake or that passing is allowed during specific times doesn't align with the unambiguous nature of the sign's prohibition. Similarly, suggesting that vehicles must enter a designated area does not connect to the concept of overtaking, which directly relates to the act of one vehicle passing another.
