These items are small, visual indicators mandated by the New York City Taxi and Limousine Commission (TLC). They are affixed to seat belts in for-hire vehicles licensed by the TLC. Their primary function is to remind passengers to fasten their seat belts before commencing their journey. An example would be a brightly colored adhesive label prominently placed on both ends of the rear passenger seat belts in a taxi.
The presence of these visual cues reinforces passenger safety, encouraging compliance with traffic laws and reducing the risk of injury in the event of an accident. Their implementation reflects a broader commitment to safety within the for-hire vehicle industry. Historically, they represent one measure among many instituted by the TLC to enhance passenger protection and driver accountability.
