Contact Congress about H.R. 3649: Magnus White Cyclist Safety Act of 2025

This bill requires automatic emergency braking in new light vehicles to detect cyclists, motorcyclists, and pedestrians. The systems must work in daylight and low light and for people of all skin tones and clothing colors. Car makers would get about two years to comply after the rule is finalized.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

Magnus White Cyclist Safety Act of 2025 is a House bill in committee. The latest recorded action: Referred to the Subcommittee on Highways and Transit.

Latest action on H.R. 3649: Referred to the Subcommittee on Highways and Transit.

Who this affects: This bill mainly affects car manufacturers, who would need to upgrade their automatic braking technology to meet new federal standards. Over time, it also affects anyone who rides a bike, walks, or rides a motorcycle near roads, since the goal is to make vehicles better at detecting them and braking before a crash.

Why this matters: Thousands of cyclists, pedestrians, and motorcyclists are killed on U.S. roads every year, and current automatic braking systems are not required to detect them. This bill would create the first federal standard specifically aimed at making these systems work for people outside of cars, which could save lives as the technology becomes standard in new vehicles.

Key provisions in H.R. 3649

  • Orders the Department of Transportation to create a final safety rule for automatic emergency braking systems in certain new vehicles.
  • Covers passenger cars, multipurpose passenger vehicles, and light trucks weighing 10,000 pounds or less.
  • Requires automatic emergency braking to work in both daylight and low-light conditions.
  • Requires systems to meet the maximum activation speed that makes sense for each covered vehicle type.
  • Requires the systems to detect and respond to vulnerable road users, including cyclists and motorcyclists, across all skin, clothing, and protective gear colors.
