Introduction
Officers play an important role in the enforcement of parking regulations in the District of Columbia. The
city is busy with lots of vehicles and officers need to be able to identify the characteristics of vehicles.
Officers also need to know how to complete a Notice of Infraction (NOI) when they see parking violations.
This lesson identifies the source for the laws that support parking infractions and some of the most
common infractions that are encountered on the street. It will also look at the exceptions for parking
regulations found in the DC Code and DCMR.
12.1.1 Describe characteristics used to identify an individual automobile
Vehicle Tag
Residents of the District of Columbia are required by law to display DC vehicle tags. Vehicles are required
to display two current tags, one on the front and the other on the rear of the vehicle. Exceptions are
motorcycles, mopeds and trailers for which one tag is issued, to be displayed on the rear of the vehicle.
The tags are to be securely fastened in a horizontal position to the vehicle for which they are issued.
District law requires that the tags be visible and may not be obstructed or covered with any substance
(e.g., glass, plastic or spray). Vehicles registered outside of DC are required to display tags required by
their home state.
Vehicle Identification Number
The vehicle identification number is commonly abbreviated as VIN. A VIN is a unique serial number, used
by the automotive industry to identify individual motor vehicles, motorcycles, scooters, and mopeds. The
VIN is unique to each vehicle and can be used to identify the owner. The VIN is located on the vehicle in
one of several locations. Three of the most common locations are the driver’s side lower windshield, the
driver’s side door frame, and on a placard or sticker in the engine compartment.
Inspection
DC residents are required to have their vehicles inspected prior to registration with the DMV. Passenger
vehicles receive an emission inspection that is valid for two (2) years; commercial vehicles receive an
emission and safety inspection that is valid for one (1) year; and vehicles for-hire receive an emission,
safety and District of Columbia Department of For-Hire Vehicles (DFHV) inspection that is valid for one (1)
year. The inspection sticker for DC registered vehicles is located on the lower passenger side of the
vehicle’s front windshield.
Vehicle Make
The make refers to the manufacturer of the vehicle (e.g., Ford, Chevrolet, Dodge, and BMW).
Vehicle Model
The model is manufacturer specific and is the proprietary name or number for a particular vehicle (e.g.,
F150, Explorer, Wrangler, Colorado, or Edge).
Vehicle Body Style
In Washington DC there are twenty-five (25) official body styles and each has a standard abbreviation.
