What is the minimum width of a curb cutout?

The minimum width of a curb cutout being 900 mm is based on accessibility standards designed to accommodate individuals with mobility challenges. This specific width ensures that wheelchairs can maneuver easily in and out of the cutout, facilitating safe passage for users. Additionally, a 900 mm width allows for the necessary space not only for the wheelchair itself but also for a user who may be accompanied by an assistant.

In practice, the width is established from guidelines that aim to provide an equitable environment for all individuals, promoting inclusivity in urban design. Curb cutouts designed to this specification ensure compliance with regulations like the Americans with Disabilities Act (ADA) in the United States, which sets parameters to enhance accessibility in public spaces.

Other widths presented in the options may not universally meet the same standard of accessibility when considering various users and their mobility devices. This specificity helps guard against safety issues that could arise if narrower cutouts were used, emphasizing the importance of adhering to the established minimum width.
