What does an Approach Sign look like?

1. A Yellow Squared sign with an A in the middle of it

2. A white rectangle with a large A in the middle of it

3. A rectangle on top split in half yellow half red

4. A red diamond with STOP in the middle of it

The correct answer is: A Yellow Squared sign with an A in the middle of it

An Approach Sign is a yellow squared sign with a letter A prominently displayed in the middle. This sign serves as a warning to train operators, indicating that they are approaching a signal that requires attention. The yellow color signifies caution, alerting conductors to prepare to slow down or be ready for upcoming signals or conditions. The distinct shape and color combination of the sign are standardized to ensure clear visibility and immediate recognition by train operators. The other sign options do not correctly represent the Approach Sign. For instance, while a white rectangle might suggest a different type of informational sign, it does not convey the specific warning associated with approaching a signal. The description of a rectangle split in half yellow and red does not match the characteristics of an Approach Sign either; it may represent a different signal type found in rail systems. Finally, a red diamond with STOP is indicative of a stop signal rather than an approach signal, which has a different meaning within the signaling system. Each of these alternatives serves distinct purposes, emphasizing the importance of recognizing specific signage when operating trains.
