The Highway Safety Improvement Program (HSIP) works to achieve a significant reduction in traffic fatalities and serious injuries on public roads through the implementation and guidance of the SHSP.
The HSIP Manual is aligned with the Arizona SHSP and will be updated periodically when SHSP updates takes place.
