The Vehicular Noise Reduction Act of 2025 aims to mitigate excessive vehicular noise in the District of Columbia through a comprehensive approach that includes a two-year demonstration program utilizing photo noise violation monitoring devices. The bill mandates the implementation of a noise camera pilot program, along with operator training and calibration requirements for these devices. Additionally, it requires the Department of Transportation (DDOT) to study strategies for reducing vehicular and transit noise and establishes a vehicle repair subsidy program to help vehicle owners comply with noise limits. The legislation also emphasizes the health impacts of noise pollution, particularly on vulnerable communities, and seeks to enhance the quality of life for District residents.

The bill outlines a process for the Council's review of proposed rules, stating that if the Council does not act within a 45-day period, the rules will be deemed disapproved. It also specifies that the act will only take effect after its fiscal impact is included in an approved budget and financial plan, with the Chief Financial Officer responsible for certifying this inclusion. The act will be effective following approval from the Mayor or a Council override of a veto, a 30-day congressional review period, and publication in the District of Columbia Register.
