Indiana Bureau of Motor Vehicles Permit Practice Test

Which of the following statements about eight-sided traffic signs is true?

1. They are used exclusively for yield signs

2. They are always electronic and change based on traffic conditions

3. They instruct drivers to either stop or yield at intersections

4. They are primarily used to indicate lane changes

The correct answer is: They instruct drivers to either stop or yield at intersections

The statement indicating that eight-sided traffic signs instruct drivers to either stop or yield at intersections is accurate because eight-sided signs are specifically designated as stop signs. These signs are universally recognized to mean that drivers must come to a complete stop at an intersection before proceeding, ensuring safety by allowing them to assess the traffic conditions. While there may be other traffic signs that indicate actions related to yielding or stop conditions, the distinct shape of the eight-sided sign is a clear and standardized signal for stopping. The use of this shape helps to create consistency across different regions, aiding drivers in recognizing their meaning quickly. In contrast, the other statements do not accurately reflect the function or characteristics of eight-sided signs. They are not used exclusively for yield signs (which are triangular), are not always electronic, and they do not indicate lane changes, which would belong to other types of signage.
