Philadelphia Drivers License Practice Test

What should one expect when encountering a 'Traffic signals ahead' sign?

1. Longer travel time

2. Potential stop at a red light

3. The need for a lane change

4. No impact on driving behavior

The correct answer is: Potential stop at a red light

When encountering a 'Traffic signals ahead' sign, one should expect a potential stop at a red light. This sign serves as a warning that traffic signals are located further down the road, indicating that drivers may need to slow down and prepare for a traffic signal change. Understanding this warning is crucial for safe driving because it alerts you to upcoming intersections or locations where traffic patterns can change suddenly due to signals. This anticipation allows drivers to approach the signals with caution and adjust their speed accordingly, ensuring they are prepared to stop for red lights or proceed with caution if the light turns green. The other options do not appropriately address the significance of the sign; it does influence how one should approach the area by being aware of traffic controls.
