What is the minimum requirement for a passing space in an accessible route for wheelchairs?

The minimum requirement for a passing space in an accessible route for wheelchairs is generally specified to be 200 feet. This is based on accessibility standards that ensure people using wheelchairs have enough space to maneuver safely, including the ability to pass one another. The requirement reflects the need for a clear and unobstructed pathway that accommodates not just the width of the wheelchair but also provides additional space for turning or navigating around obstacles. Adhering to these guidelines promotes safety and accessibility for all individuals, particularly those with mobility challenges. The other options do not meet the established standards for compliance, making 200 feet the correct choice.
