Nuro’s driverless delivery vehicles just got another important approval. California’s DMV has given Nuro a permit to test completely self-driving couriers in specific parts of Santa Clara and San Mateo counties, including Silicon Valley mainstays like Mountain View, Palo Alto and Sunnyvale. The company plans to use this for free deliveries to “select” customers in the Mountain View area, with ultimate plans for a full-fledged delivery service that would operate state-wide.

The startup already had permission to test self-driving vehicles on California roads since 2017, but only with a backup driver in place. Truly driver-free deliveries have already taken place in other states, if typically as test programs.
