Which color is used to increase bike lane visibility?

• A. Green
• B. Blue
• C. Yellow
• D. Red

Answer: (A)

Using color on pavement is a way to communicate space use and focus attention where vulnerable road users are present. Green pavement is used to boost bike lane visibility because it stands out clearly against the typical gray of asphalt and against white lane markings. This distinct cue helps drivers notice the bike lane, especially at tricky spots like intersections, merges, or driveways, and reinforces that the space is meant for bicyclists rather than motor vehicles. The result is a calmer, safer interaction between drivers and people biking, since encroachment into the bike lane becomes more visually obvious and less likely.

Other colors serve different signals in some places, but they don’t carry the same widely adopted association with bike facilities. Blue is often linked to accessibility markings in many jurisdictions, yellow signals caution or general hazards, and red can indicate transit-related areas or other restricted zones. None of these convey bike-lane priority as consistently as green does.
