What color should the front and side lights be in a pre-trip inspection?

The front and side lights of a commercial vehicle should be amber in color during a pre-trip inspection. Amber lights serve as a warning and signaling feature, making the vehicle visible to other road users and indicating its presence, especially during low-light conditions or inclement weather. This color is standardized for vehicles to convey information about their status, such as being in transit or indicating a turn.

Using amber lights helps prevent confusion; for instance, red lights are typically reserved for stop signals or brake lights. Similarly, blue and green lights are used for emergency and specific authorization purposes, respectively. Ensuring your vehicle adheres to the color coding for lights is crucial for safety and compliance with roadway regulations.
