What is the shape of a "keep right" sign, and how should the driver react when he sees one?

The shape of a "keep right" sign is a vertical white rectangle, which is a standard design used to convey regulatory information. When a driver sees a "keep right" sign, it indicates that they must stay to the right side of a specified point, such as a median or a diversion, to ensure safe traffic flow. This is particularly essential in areas where the road may have obstructions, constructions, or specific traffic patterns, helping to guide drivers to navigate safely.

Understanding the shape of the sign is critical because it is an official regulatory sign that instructs drivers on the appropriate behavior on the road. Recognizing and following the directive helps maintain order and safety on the streets.
