Its purpose is to inform drivers of an upcoming traffic signal, allowing them to prepare to stop or adjust their speed as necessary. Below is a detailed explanation:
1. Purpose of the Sign:
- This warning sign alerts drivers that they are approaching an intersection or area controlled by traffic lights.
- It provides sufficient advance notice to allow drivers to prepare for changes in the signal.
2. Importance of Awareness:

- Being prepared can prevent accidents and ensure smooth traffic flow.
3. Relation to Speed:
- The sign does not indicate that speeding is not allowed (as speeding is always prohibited).
- It also does not require you to stop immediately; you only need to stop if the light is red when you reach the intersection.
4. Safety Tips:
- Slow down slightly and scan the road ahead.
- Be prepared to stop if the light changes to yellow or red as you approach.
- Watch for pedestrians, cyclists, or other vehicles that might also be responding to the signal.

- Misinterpreting this sign as a stop sign may cause unnecessary halts and confusion.
- Ignoring it could result in running a red light if the driver is not prepared for a signal change.
In summary, this sign is about being prepared for an upcoming traffic signal. Awareness and proper response ensure road safety and help reduce traffic disruptions.
