What must be verified about the turn signals during a pre-trip inspection?

During a pre-trip inspection, it is essential to verify that all turn signals are operational and visible. This is crucial for safety on the road, as functioning turn signals are vital for communicating a vehicle's intended direction to other drivers. If a turn signal is not operational, it can lead to miscommunication, increasing the risk of accidents. Additionally, the visibility of the turn signals ensures that other road users can clearly see the indicators, which is especially important in various weather conditions or at night.

While other factors like color, symmetry, and cleanliness are relevant for overall vehicle safety and maintenance, the primary concern during the pre-trip inspection focuses on the operational status of the turn signals and their visibility. This helps ensure that the vehicle adheres to safety regulations and operates effectively in traffic conditions.
