established by the New York State Department of Environmental Conservation in 6
NYCRR Part 217.
(e) General provisions.
(1) Vehicles registered in this State. All
non-exempt motor vehicles registered in this State are subject to either an OBD
II or low-enhanced emissions inspection. All non-exempt vehicles must pass the
appropriate emissions inspection and the appropriate safety inspection before
any inspection certificate may be issued. All non-exempt motor vehicles with a
make of "custom" or "homemade" are subject to a low-enhanced emissions
inspection and must only pass the requirements of subdivision (i), item 8b of
this section.
(2) Vehicles
registered in another state. If a non-exempt motor vehicle with a registration
from another state, or with a New York State registration with an out-of-state
address, is presented for inspection at an official inspection station, the
inspection station must perform the inspection procedure appropriate for the
vehicle as if it were registered in the county where the inspection is to be
performed, and shall issue the appropriate safety or safety/emissions
inspection certificate if it passes the inspection.
(f) Effect of failure of emissions inspection.
(1) OBD II inspection.
(i) Subject vehicles must pass the OBD II
emissions inspection (which includes subdivision [i], items 1-10 of this
section, except that diesel-powered vehicles that are subject to the OBD II
emissions inspection shall not be inspected for items 1 through 8b in
subdivision [i] of this section), and safety inspection in order for an
inspection certificate to be issued. If the vehicle fails any portion of the
inspection, the inspection station must give the motorist a CVIS-generated
inspection receipt indicating the reason for failure. An inspection station
cannot issue a certificate of inspection until appropriate repairs are made and
the vehicle passes all applicable portions of the inspection, or, until the
vehicle meets the conditions in section
79.5(a) of this
Part and qualifies for an emissions waiver.
(2) [Reserved]
(3) Low enhanced inspection.
(i) An inspection station shall only issue an
inspection certificate if the subject vehicle passes the low enhanced emissions
inspection (subdivision [i], items 1-8 of this section) as well as the safety
inspection. If the vehicle fails any portion of the inspection, the station
must give the motorist a CVIS-generated inspection receipt indicating the
reason for failure. A certificate of inspection cannot be issued until
appropriate repairs are made and the vehicle passes all applicable portions of
the inspection. Vehicles subject to the low enhanced inspection cannot qualify
for an emissions waiver.
(g) OBD II and low enhanced emissions inspection reinspection and fees.
(1)
If a vehicle fails the safety portion and/or the emissions portion of the
safety/emissions inspection, and is not removed from the station by the
customer for repair, the station may not charge for reinspection of the
vehicle. A test drive by station personnel for the purposes of diagnosis or
verification of repair does not constitute removal from the station.
(2) If a vehicle fails both the safety
portion and emissions portion of the safety/emissions inspection, is removed
from the station by the customer for repair, and if the vehicle is presented
for reinspection, that inspection station or any other emissions inspection
station must conduct a full inspection of both the safety portion and emissions
portion during the reinspection of the vehicle, and may charge a fee up to but
not more than the applicable fee for the failed portions as set forth in
section 79.7(c) of this
Part.
(3) If a vehicle fails the
safety portion or the emissions portion of the safety/emissions inspection, and
is removed from the station by the customer for repair and if the vehicle is
presented for reinspection within 30 days of the rejection, that inspection
station or any other emissions inspection station must conduct a full
inspection of only the failed safety or emissions portion during the
reinspection of the vehicle, and may charge a fee up to but not more than the
applicable fee for the failed portion as set forth in section
79.7(c) of this
Part.
(4) If a vehicle fails the
safety portion or emissions portion of the safety/emissions inspection, and is
removed from the station by the customer for repair and if the vehicle is
presented for reinspection more than 30 days after rejection, that inspection
station or any other emissions inspection station must conduct a full
inspection of both the safety portion and emissions portion during the
reinspection of the vehicle, and may charge a fee up to but not more than the
applicable fee for the safety portion and emissions portions as set forth in
section 79.7(c) of this
Part.
