Plug-in Electric Vehicle (PEV) Parking Space Regulation
An individual may not park a motor vehicle within any on- or off-street parking space specifically designated by a local authority for parking and charging PEVs unless the vehicle is a PEV fueled by electricity. Eligible PEVs must be in the process of charging to park in the space. A person found responsible for a violation is subject to traffic violation penalties.
PEV parking spaces count as at least one space toward minimum parking requirements.
