What is indicated by a "do not pass" sign?

The "do not pass" sign indicates that drivers must not pass another vehicle where these signs are posted. This type of signage is usually placed in areas where passing is dangerous, such as on hills, curves, or intersections where visibility is limited. The purpose of this sign is to enhance safety by preventing vehicles from overtaking each other in situations where it could lead to collisions or accidents.

When a "do not pass" sign is present, it is critical for drivers to adhere to this directive to maintain safe driving conditions not only for themselves but also for other road users. Understanding the implications of such a sign helps in promoting adherence to traffic regulations, ultimately lowering the risk of crashes in those specific areas.
