What is the CTA's policy regarding food and drinks on buses?

The CTA’s policy regarding food and drinks on buses aims to maintain cleanliness and ensure comfort for all passengers. The correct choice emphasizes that food and drinks are generally not allowed unless they are in spill-proof containers. This policy is in place to prevent spills and messes that can disrupt the bus environment, potentially create hazards, and cause extra work for maintenance. Allowing only spill-proof containers helps to mitigate the risks associated with consuming food and drinks while traveling on the bus, ensuring a more pleasant experience for all riders.

The context behind this policy reflects a balance between accommodating passengers’ needs and protecting the integrity of the transit system. Other options suggest either a more lenient approach to food and drinks, which could result in undue mess and discomfort, or imply that all snacks are unrestricted, which does not align with the CTA’s guidelines promoting cleanliness and safety.
