Summary

The District of Columbia Department of Transportation (DDOT) received a $1,485,270.04 formula grant award from the National Highway Traffic Safety Administration (NHTSA) under the National Priority Safety Programs (CFDA 20.616), Section 405(D) Impaired Driving Countermeasures Grant program, effective October 1, 2025, through September 30, 2029. This award supports DDOT's implementation of evidence-based impaired driving countermeasures programs designed to reduce motor vehicle crashes, injuries, and fatalities in Washington, D.C. The funding enables DDOT to develop and enforce programs addressing impaired driving, including adoption and enforcement of mandatory alcohol-ignition interlock laws and 24/7 sobriety programs that align with the District's triennial highway safety plan and approved annual grant applications.

As a state and territorial highway safety office, DDOT will utilize these funds to execute specific countermeasure strategies and projects identified in its problem identification and performance measures framework. The grant requires DDOT to document planned projects through approved annual grant applications, maintain compliance with applicable regulations under 23 Code of Federal Regulations Part 1300.23, and track performance outcomes related to the reduction of impaired driving-related crashes and fatalities. Reimbursement of the federal share occurs through voucher claims submitted for actual costs incurred, with all funding transfers conducted through electronic methods.
