What should the condition of the taillights and brake lights be, according to inspection standards?

The condition of the taillights and brake lights is critical for safety during vehicle operation, making it essential for these lights to be in proper condition. The correct answer states that all lights must be of the proper color and operational. This means that both taillights and brake lights should function correctly—illuminating when needed and displaying the correct colors (red for taillights and typically red for brake lights) to convey signals to other drivers.

Having operational lights is crucial for visibility and safety on the road, as they signal stops and intentions to other drivers, minimizing the risk of accidents. Proper color ensures that there is no confusion about the vehicle's actions, enhancing communication among road users.

In contrast, options suggesting that the lights be cracked, broken, or missing would pose significant safety hazards, compromising visibility and signaling efficacy, while indicating a lack of adherence to inspection standards.
