Key Findings

1. A national approach to funding traffic crash intervention is less expensive than a state-specific approach, but it might not be as effective.
2. The new, free-to-use tool, Motor Vehicle Prioritizing Interventions and Cost Calculator for States, can help decisionmakers measure the cost-effectiveness of traffic crash–intervention policies and programs in their states.

In the United States, each state is responsible for implementing policies to reduce vehicle crashes.^[1] Policies can vary between states but often include measures to deter speeding, prevent driving while intoxicated (DWI), and increase the use of seat belts and motorcycle helmets. Supporting these policies is expensive; states pay millions of dollars each year for police time, equipment, and more. Thus, state policymakers must prioritize and choose the interventions that will provide the greatest reduction in injuries and deaths for their implementation dollars.
