What color must the front turn signals be?

The front turn signals on a vehicle must be amber, as this color is universally recognized for signaling turning intentions to other drivers. The use of amber is significant because it provides clear visibility and distinction from other lights, particularly headlights and taillights, allowing for quick recognition of a driver's actions. While white may be used for front clearance or marker lights, it is not acceptable for turn signals. Thus, the requirement of amber ensures consistency across vehicles and enhances safety on the road by avoiding any confusion with other signal colors.
