What are PDD's?
Personal Delivery Devices (PDDs), also known as delivery robots, are ground delivery robots that are remotely operated, self-driving, or both. Under Pennsylvania law, PDDs:
- Are defined as pedestrians,
- Can weigh up to 550 pounds empty, and
- Can operate at speeds up to 12 miles per hour on sidewalks.
- Are permitted to operate in any pedestrian area (ie sidewalk) or on a roadway with a posted speed limit of 25mph or less
Pennsylvania law prohibits local authorities from regulating the operation of PDDs. This means PennDOT has the sole authority to authorize a company to operate PDDs and regulate the time, place, and manner in which the PDDs operate.
PDDs may operate in two phases. In Phase 1 deployments, a PDD operator must be within 30’ of the PDD. In Phase 2 deployments, the PDD may be monitored remotely.
