Building a Movement for Street Safety: Lessons from Dan Langenkamp and the Ride for Your Life

When Foreign Service Officer Sarah Debink Langenkamp returned to the U.S. after managing a $600 million program in Ukraine, she chose to ride her bike as often as she could—to enjoy the outdoors and live lightly on the planet. But riding home from her children’s school in Bethesda, Maryland, she was struck and killed by a turning truck.

In the wake of her loss, her husband, Dan Langenkamp, was forced to confront a devastating reality: the national epidemic of traffic violence. The year Sarah died was the deadliest year for pedestrians in forty years and the deadliest on record for cyclists. But rather than letting grief remain silent, Dan turned tragedy into an engine for national legislative change, giving rise to the Ride for Your Life movement.

At WalkMassachusetts, we know that transforming our roadways requires more than just mourning losses—it demands organizing communities and pushing directly for systemic policy fixes. Dan’s journey from a single memorial ride in D.C. to massive multi-city events in Boulder, Madison, and Boston offers a powerful blueprint for effective road safety advocacy:

• Center the Human Experience: Every event centers on a real person—like Sarah, Magnus White, or Louisa Gag—putting a personal face on statistics that decision-makers too often treat as abstract numbers.

• Pair Remembrance with Direct Policy Asks: Memorials must drive actionable legislative changes. Dan’s efforts helped pass state-level safety bills and introduced federal acts like the Sarah Debink Langenkamp Active Transportation Safety Act and the Magnus White Cyclist Safety Act.

• Unite Pedestrians and Cyclists: True safety advocacy spans all vulnerable road users. By intentionally pairing bike rides with accessible, one-mile “Walks for Your Life,” these events invite families, walkers, transit riders, and cyclists of every age and ability to stand together.
  
• Build Broad Coalitions: Winning real policy requires coordination between local bicycle and pedestrian advocacy organizations, victim advocacy groups like Families for Safe Streets, municipal leaders, and industry partners.

Whether we are addressing truck safety regulations, closing gaps in pedestrian infrastructure, or tackling vehicle speeds, systemic change happens when leaders see a unified constituency demanding better. As Dan reminds us, our roadways aren’t built for throughput speed alone—our streets exist for everyone.

Join WalkMassachusetts and the Ride for Your Life at our upcoming local events to help us push for safer, more accessible streets across the Commonwealth.
