What happens to the warning lamps on newer vehicles when the ignition is first turned on?

When the ignition of a newer vehicle is turned on, the warning lamps illuminate as a part of a self-check system to ensure that all lights are functioning correctly. This initial illumination allows the driver to verify that each warning light is operational and to identify any potential issues with the vehicle’s systems. After a moment, these lights will turn off if everything is functioning properly, indicating that there are no malfunctions to report. This process is crucial for promoting vehicle safety, as it ensures that drivers are aware of any problems before they start driving. The other choices do not accurately reflect the vehicle's self-diagnostic features at startup.
