As the Service Authority for Freeway Emergencies (SAFE) for Merced County, MCAG manages a network of 88 call boxes on Interstate 5 and State Routes 99 and 152. The call boxes provide motorists in need with a 24 hour direct link to the California Highway Patrol. This program is a joint project of MCAG, Caltrans, and the California Highway Patrol.
MCAG is currently proposing the removal of all call boxes in Merced County. With the prevalence of cell phones, call boxes are increasingly underutilized which provides the opportunity to consider alternative uses for the funding that would provide a greater benefit to the region.
