D.C. Windshield Rules: No Non-Transparent Material, No Named Dash Cam Exemption

Two District rules govern where a camera can go, and neither is drafted around cameras. The first is 18 DCMR § 731.1, in the motor vehicle equipment chapter. It prohibits driving any motor vehicle with any sign, poster, or other non-transparent material upon the front windshield, sidewings, or side or rear windows, and its exception clause is a closed list of one item: a sticker authorized by the Mayor, the Public Service Commission, the Joint Board, or the Director of the Department of Motor Vehicles. Nothing in Chapter 7 adds a device, camera, transponder or navigation-display allowance to that list, so a windshield-mounted camera body has no express permission the way it does in states that legislate a named exemption and a permitted mounting square.

The second is 18 DCMR § 2213.1, in the moving-violations chapter. It is a functional test rather than a location ban: no person shall drive a vehicle with any object in any position that obstructs a significant portion of the view of the driver to the front or sides of the vehicle, or interferes with the driver's control over the driving mechanism. Section 2213.4 adds the general duty that an operator shall give full time and attention to the operation of the vehicle, which is what a screen playing back footage while driving would engage.

Read together, the two rules point at the same practical answer. A camera fixed to the dashboard, or tucked high behind the rear-view mirror so it covers no significant part of the forward view, engages § 2213.1 only if it actually obstructs a significant portion of the view; a unit stuck out in the middle of the windshield engages both § 2213.1 and the flat prohibition in § 731.1 on non-transparent material upon the windshield. The District has drawn no measured allowance, no square-inch limit and no corner exception, which is what distinguishes it from jurisdictions that let a device occupy a stated area of the glass.

Section 731 also carries the surrounding windshield duties that an inspection or a stop can pick up: § 731.2 requires a mechanically operated cleaning device controlled by the driver, § 731.3 requires wipers capable of clearing the right and left hand sides of the windshield on any vehicle built after January 1, 1938, § 731.4 requires each wiper to be kept in good working order, and § 731.5 bars operating a vehicle whose windshield is cracked, scarred, clouded or otherwise defective so as to obstruct vision. Section 731.6 requires a mirror giving a view of at least two hundred feet to the rear under all conditions of loading, which matters when a camera or its cabling is fitted near the mirror head.

One conflict between two in-force District instruments is worth knowing about. The current text of § 2213 marks subsection 2213.7 as [REPEALED], and the repeal came through the Neighborhood Engagement Achieves Results Amendment Act of 2016 and the Public Safety Technical Amendments Amendment Act of 2016. Yet the moving-infraction fine schedule at 18 DCMR § 2600, adopted effective August 7, 2026, still prints a $15 fine for "Sticker Regulation, Sign or other unauthorized item attached to the mirror, window, or window frame [§ 2213.7]". The priced subsection no longer exists, so the live exposure for a windshield-mounted device is the $75 vision and windshield entries rather than that $15 line.

There is no District recording-consent obstacle to running a dash camera that captures the road, but audio is a separate question governed by the District's wiretap law rather than by any provision of Title 18.

18 DCMR § 2600, effective August 7, 2026, prices "Vision, Front or side; obstructed" under § 2213 at $75 and "Objects hanging so as to obstruct" under § 2213 at $75. The same schedule prices "Windshield, Defective or obstructed" under § 731 at $75, failure to have windshield wipers at $75, wipers not in operating condition at $25, and no rear-view mirror under § 731.6 at $75. It also still lists a $15 fine under the repealed § 2213.7 for an unauthorized item attached to the mirror, window or window frame. Citations are issued by the Metropolitan Police Department and adjudicated by the Department of Motor Vehicles; a Chapter 7 breach can additionally be prosecuted under D.C. Code § 50-2201.03(f), which carries up to 90 days and a fine capped at $500 by § 22-3571.01(b)(3). A vehicle can also be failed at its periodic inspection under 18 DCMR § 601.
