What does the code 10-25 signify?

The code 10-25 signifies "dirty vehicle or facility." In the context of transit operations, maintaining cleanliness and proper sanitation in vehicles and facilities is vital for ensuring passenger safety and comfort. When operators use the code 10-25, they are communicating a need for attention to a specific vehicle or facility that may not meet cleanliness standards, indicating that maintenance or cleaning is required. This helps ensure that issues are addressed promptly and helps maintain the quality of service provided to riders.

Other codes serve different functions; for example, "message received and understood" communicates acknowledgment and understanding of a previous communication, while "gap filler" typically refers to service adjustments to address passenger needs, and "in service" indicates that a bus or train is currently operating on its designated route.
