Texas State Inspection Practice

What color must the turn signal lights be in the rear?

1. Amber or Red

2. White

3. Red

4. Green

The correct answer is: Amber or Red

The turn signal lights in the rear of a vehicle must be amber or red as a requirement set by safety regulations. Using amber is standard practice because it is clearly visible and universally recognized as a signaling color, helping to indicate a driver's intention to turn or change lanes. Red is also acceptable for turn signals, particularly in certain vehicle designs, ensuring they are easily identifiable to other drivers. The other colors listed do not comply with safety regulations for rear turn signals. White is commonly used for reverse lights, while green is not typically used in vehicle lighting for turn signals and could create confusion for other drivers. This regulation is designed to enhance visibility and ensure clear communication between drivers, contributing to road safety.
