Effectiveness: 1 Star Cost: Varies
Use: High
Time: Medium

This countermeasure involves communications and outreach campaigns promoting the use of protective clothing and measures that increase rider conspicuity, such as clothing and auxiliary devices. Measures that may increase rider conspicuity include wearing brightly colored clothing, clothing that incorporates retroreflective materials, and/or white- or bright-colored helmets (for increased visibility during day or night). Additional solutions include the use of continuous headlights, auxiliary head and brake lights, and flashing headlights.

Effectiveness Concerns: This countermeasure is widely used, but it has not been extensively studied. There is some evidence that certain approaches may lead to limited positive outcomes; however, there are insufficient evaluation data to determine the extent of effectiveness.

Further information about the known research, potential effectiveness, costs, use, and time to implement is available in Appendix A5, Section 4.1.
