What signal should you check for during a pre-trip inspection?

During a pre-trip inspection, it is essential to check for all indicator lights, particularly the left and right indicator lights. These signals are crucial for safe driving, as they communicate the vehicle's intended direction to other drivers, which helps in preventing accidents during lane changes or turns. Ensuring that both left and right indicator lights are functioning properly verifies that the vehicle is roadworthy and compliant with safety regulations.

Focusing solely on one type of light or signal, such as only the high beam indicator, hazard lights, or fog lights, does not provide a comprehensive understanding of the vehicle's signaling system. Each type of signal plays a distinct role in safe vehicle operation, and a thorough pre-trip inspection necessitates checking all relevant lights and indicators.
