For recordkeeping purposes the DMV segregates vehicles into six classes:

• Class A: Non-commercial passenger vehicle
• Class B: Commercial vehicle, tractor, and passenger-carrying vehicle for hire having a capacity of at least 8 passengers
• Class C: Trailer
• Class D: Motorcycle
• Class E: Motorized Bicycle (moped)
• Class F: Historic Motor Vehicle

There are presently two levels of annual passenger vehicle registration fee: $72 for vehicles that weigh less than 3,500 lbs., $115 for heavier vehicles. These fees, which are doubled for motorists that request the optional two-year registration, went into effect on March 6, 2003. They represent a 30% increase over the previous fees. Weight-based registration fees for trailers range from $20 to $431 annually. For motorcycles and mopeds, the annual fee is $30 and $10, respectively.

D.C. plates of all types may not be transferred from one individual to another with the sole exception of personalized plates, which may be transferred only to a surviving spouse, from joint ownership of a vehicle to sole ownership, or from sole to joint ownership.

Non-residents may maintain and operate vehicles properly registered elsewhere within the District for a period not to exceed 30 continuous days. To keep a non-D.C.-registered vehicle in the District for more than 30 days, a D.C. registration must be purchased unless the motorist purchases a reciprocity sticker. This allows the vehicle to remain in D.C. for an additional 180 days. Only a single 180-day sticker may be purchased by a non-resident during a calendar year. Fees for these stickers are $25 if the vehicle is not kept in the District and $125 if it is.

It takes more than a pair of license plates to prove that a vehicle is properly registered in the District of Columbia. Examples of the three required devices, all attached to a 1998 Honda Civic, are shown here. Most evident, of course, is the set of plates, but two windshield stickers are also displayed. At the upper right is the registration sticker, which in this case shows an expiration date of Sept. 14, 2007. It is displayed in the lower left corner of the windshield, and the "Zone 3" notation indicates the portion of the city in which the vehicle is permitted to be parked. The purpose of the orange sticker, displayed in the lower right corner of the windshield, is indicated by SAFETY/EMISSIONS CERTIFICATE printed across the bottom. Note that both stickers include the matching registration (license plate) number and all or at least a portion of the vehicle identification number.

D.C. Vehicle Registration Statistics

To license plate collectors, one of the most intriguing aspects of Washington, D.C. plates is their scarcity as compared to plates from the states. This scarcity is a result of the relatively small number of plates made and issued, which, in turn, is a function of D.C.'s population and the number of vehicles owned by residents. As a city with public transportation and limited parking, many of the District's 572,000 residents cannot or choose not to own a vehicle.

Although there is undoubtedly a correlation between the number of reported registered vehicles within and the number of plates from a particular jurisdiction, an analysis to identify that relationship is beyond the scope of this resource. However, suffice it to say that the number of registrations reported in a single period (most commonly a single calendar year) is not the number of plates made and issued. D.C. plates of most types are issued in pairs, so there are actually two plates for every registered vehicle, but all reported registrations are not valid at any single point in time.

Therefore, although registration statistics are not a relaible indicator as to how many plates exist from a particular jurisdiction for a certain year, they do provide a good basis for determining the relative scarcity of plates of various jurisdictions, as well as for comparing the scarcity of various plate and registratrion types of one jurisdiction. It is for these purposes that the data below has been presented. Unless noted otherwise, its source is the U.S. Dept. of Transportation, Federal Highway Administration.

The number of D.C. vehicle registrations decreased by 12.3% between 1992 and 2003. Here are the 1992 statistics:

	Automobiles	Trucks	Motorcycles	Buses	Total
Wash., D.C.	237,619	16,018	1,398	2,769	257,804

Washington, D.C. has a much higher percentage of buses than other U.S. jurisdictions due to the concentration of sightseeing buses that cater to millions of tourists annually. In 2003, buses comprised 1.2% of all registered D.C. vehicles as compared to only 0.3% nationally. In 1992, 2,271 of the 2,769 buses registered in D.C. were privately-owned for commercial (non-school) uses, ranking it 16th in the nation for commercial bus registrations even though overall the District has, in recent years, consistently ranked number 51 in the list of states and D.C. ranked by number of registered vehicles.

Over the 50-year period ending in 2000, Washington D.C. lost 28.7% of it's 802,000 residents of 1950. Despite the long-term exodus from D.C., the number of vehicles has increased. Back in 1950, four of the 48 states had fewer registered vehicles than D.C. as indicated in this data from The World Almanac and Book of Facts for 1950:

Security Marks

A security mark is an identifying mark imprinted in the reflective sheeting used in the manufacture of most (and perhaps all) Washington, D.C. license plates since 1986. All D.C. security marks are round and appear in a repeating pattern down the center of the plate. The dark 1.25" diameter marks can be seen clearly only when the plate is viewed at a 30 degree angle, and are placed in the sheeting by its manufacturer for control purposes during the production process and as a security measure against counterfeiting.

The earliest D.C. security marks resemble the graphic reproduction (of a later mark) shown above, but include a two-digit year designation in place of the four-character code. The earlierst observed mark is dated "86", and dated "87," "88," "89," and "90" marks were also used before the year designation was replaced by a four-character code. On this second type of mark, the first three characters are letters and the last is a number (1 through 5). The first letter is always "B."

The security mark currently being used has no letters or number, but rather is a simplified graphic image of the eagle seal that appears on the right side of the reverse of a U.S. $1 bill. This style of mark has been observed only on completely flat plates of the style presently being issued.

Security marks were introduced on the 1984 (Capital City) base. The highest observed plate without a mark is 091-988 and the lowest plate with an "86" mark is 175-121. Observed security mark data is provided in the table below, although more data is clearly needed to narrow the cutoff points.
