Is this a safety guarantee?

This guidance is based on local street-scene analysis and general visibility principles. It is not a prediction of crash risk or a guarantee of safety.

Why local results differ

  • Brick, vegetation, glass, painted surfaces, asphalt, sky, and shade can change which clothing colors separate from the background.
  • Daytime pages weigh color contrast against the local backdrop; low-light pages are more conservative and emphasize brightness, reflectivity, and lights.
  • Routes with tunnels, tree cover, rain, dusk, or heavy traffic can differ from the average local image sample.

What to do

  • Add reflective details at ankles, wrists, or other moving points so drivers catch motion early.
  • Keep at least one high-contrast element on your torso.
  • If you are biking, use a front white light and rear red light in addition to reflective details.

If you are choosing from regular clothing, start with white and add reflective details at moving points. It lands at about 99% of the average high-vis score here.

If you are packing one option for Marina / Presidio low light conditions, make it white if that is what you already own. If you have high-vis gear, bright white still performs best overall.
