When determining a second intersection, what measurement is taken?

The correct approach to determining a second intersection involves measuring from the center of the base intersection to the collision location. This method provides an accurate reference point, establishing a clear spatial relationship between the intersection and the incident site, which is crucial for accident analysis and documentation.

Using the center of the base intersection as a starting point allows investigators to create precise diagrams and reports, facilitating better understanding and communication of the collision context. This measurement identifies the location of the incident concerning a known landmark, which is essential in assessing roadway conditions, visibility, and other factors related to traffic incidents.

Other methods, such as measuring from highway signs, service stations, or along unsurfaced paths, do not offer the same level of accuracy and could lead to misinterpretation of the incident’s location in relation to the formal road network. This precision is vital for legal, insurance, and safety evaluations, making the center of the base intersection a standard practice in determining points of interest regarding collision investigations.
