What color are the front turn signals on a bus or trailer that is greater than 80 inches in width?

The front turn signals on a bus or trailer that is greater than 80 inches in width are amber. This color is standardized to ensure visibility and uniformity across all vehicles. Amber signals are designed to capture the attention of other drivers, indicating that the vehicle is turning or changing lanes.

This choice is consistent with traffic regulations and vehicle safety laws, which specify that turn signals must be a specific color to avoid confusion on the road. The use of amber helps differentiate turn signals from brake lights, which are typically red, and headlights, which are white. This distinction plays a crucial role in ensuring that other drivers can easily interpret the signals and react accordingly, thus enhancing overall road safety.

The other colors listed—red, white, and green—are not typically used for turn signals in this context, as red is mainly reserved for brake lights, white for headlights, and green is more commonly associated with other types of signals or indicators.
