What is the minimum width of a bike lane for a road with curb and gutter?

• A. 4 ft.
• B. 5 ft.
• C. 6 ft.
• D. 7 ft.

Answer: (B)

The minimum width of a bike lane for a road with curb and gutter is typically set at 5 feet. This width provides adequate space for cyclists to safely navigate alongside vehicle traffic while also accommodating the need for comfort and safety in the presence of the curb. A 5-foot width ensures that there is enough room not only for the bike itself but also for the biker's safety when close to the curb, reducing the risk of collisions with vehicles and other obstacles. Wider bike lanes, such as those of 6 feet or more, are generally encouraged where space allows, as they can provide added comfort and safety, particularly in areas with higher traffic volumes or speeds. However, the established minimum standard of 5 feet is designed to strike a balance between safety, usability, and the physical constraints of urban roadways, making it the most accepted standard in many design guidelines, including those from the American Association of State Highway and Transportation Officials (AASHTO).
