Nyasha Smith, Secretary
Council of the District of Columbia
1350 Pennsylvania Avenue N.W.
Washington, DC 20004
Dear Secretary Smith,
Today, I, along with Councilmember Brianne K. Nadeau, am introducing the Vehicular Noise
Reduction Act of 2025. Please find enclosed a signed copy of the legislation.
The purpose of the Vehicular Noise Reduction Act is to reduce vehicular noise in the District by
(1) implementing a noise camera pilot program; (2) creating a vehicle repair subsidy program to
offset costs of vehicle repairs; and (3) commissioning a DDOT and DOEE study on strategies to
reduce vehicular and transit noise in the District.
Excessive vehicle noise, including noise caused by defective or altered muffler and exhaust systems and roadway noise from tires on pavement, is disruptive in myriad ways to District residents’ lives, including interrupting sleep;
creating noise barriers to communication in business,
educational, and social settings;
and creating continuous, high levels of noise, commonly referred
to as “noise pollution,” that can lead to various health and developmental issues.
Noise pollution, both during the day and at night, has serious effects on District residents’ physical
and mental health. Noise pollution is correlated to increased anxiety, depression, heart disease,
cognitive impairments, and strokes. Continuous exposure to high noise levels can also bring about
the “flight or fight” response within the body, triggering stress hormones that contribute to elevated
blood pressure, accelerated heart rates, and disrupted digestive systems. Sleep interruption from
loud and continuous noises can inhibit child development, learning, mood regulation, and optimal
healing from injuries, even when a person is never actually awoken by the noise.
Noise pollution from vehicles is also an equity issue in our city, as communities of color,
immigrants, and people with low incomes are more likely to live near roadways with elevated and
constant vehicular noise and are thus at greater risk of experiencing these negative health impacts.
This legislation, through its three-pronged approach, will aid in reducing vehicle noise in the
District and provide an opportunity to understand further noise-reduction options that may be
available to lower vehicular noise and improve equity, quality of life, and health for District
residents, workers, and visitors.
I previously introduced an identical version of this legislation in Council Period 25, B25- 0040.
Should you have any questions about this legislation, please contact my Legislative Director , Linn
Groft, at lgroft@dccouncil.gov.
Thank you,
Brooke Pinto

driver, the passengers, or the contents of the motor vehicle. 121
(b) Notwithstanding subsection (a) of this section, no notice of violation issued pursuant 122
to this section shall be dismissed solely because a photograph, microphotograph, videotape, or 123
other recorded image allows for the identification of the driver, the passengers, or the contents of 124
motor vehicles where the department shows that it made reasonable efforts to comply with the 125
provisions of this paragraph in case. 126
(c) Any photograph, microphotograph, videotape or other recorded image from a photo 127

Sec. 11. Vehicle and transportation noise-reducing strategies study and report. 175 8
In Fiscal Year 2026, DDOT, in consultation with DOEE, shall conduct a study on vehicle 176
and other transportation- related noise and identify and evaluate short-term and long- term 177
strategies for reducing vehicle and other transportation- related noise, including noise-reducing 178
roadway material. DDOT shall provide a report to the Council within one year of enactment of 179
this Act to include recommendations on the feasibility, efficacy, and environmental impact of the 180
identified noise-reducing strategies as well as a cost-benefit analysis of identified strategies. 181
Sec. 12. Vehicle repair subsidy program established. 182
The Department of Motor Vehicles (“DMV”) shall create a non-means tested program to 183
subsidize, in full or in part, the cost of repairing a vehicle to bring it within the motor vehicle 184
