Bay Area Rapid Transit (BART) Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

When a door is open, which of the following exterior lights will be on?

Green

Yellow

Red

When a door is open on the BART train, the red exterior lights will activate. This safety feature serves to alert both passengers and crew that the train's door is not secured, indicating a potential safety hazard. The activation of red lights helps prevent accidents and ensures that individuals nearby are aware of the open door, maintaining overall safety on the platform and near the tracks.

The other colors, like green, yellow, and blue, have different meanings or functions within the BART system and do not signal the specific condition of an open door. Green lights typically indicate that a door is closed and secured, while yellow and blue lights serve other operational or informational purposes that do not relate to door status. Thus, the activation of red lights when a door is open is essential for conveying the necessary safety information to the public and staff.
