What type of signal should you obey when driving?

When driving, it is essential to obey traffic lights and signs because they are established to regulate the flow of traffic, ensure safety, and provide important information to drivers. Traffic signals control the stop-and-go movement at intersections, while road signs convey critical information regarding speed limits, warnings about hazards, and guidance for navigation. Following these rules is vital for maintaining order on the road and preventing accidents.

Options that suggest focusing solely on one type of regulatory signal, such as just traffic police signals or only speed limit signs, do not encompass the full range of regulations that drivers must adhere to while on the road. Highway signs also play a role, but they may not provide the immediate, dynamic control that traffic lights do at busy intersections. Thus, compliance with all traffic lights and signs is crucial for safe driving practices.
