Is the lighting test in Subject 3 random or fixed?

[LePreston]

Subject 3 lighting test is randomly combined. For the simulated lighting test, it is clear that corresponding lighting operations must be performed according to the voice prompts. If one light is not operated correctly or the wrong operation is made, the test will be failed. Moreover, several questions are randomly selected, but the simulated lighting test mainly consists of a few operations, including low beam, high beam, alternating high and low beams, and turning on the hazard warning flashers. The specific content of the Subject 3 simulated lighting test is as follows: The content of the simulated lighting test mainly targets some complex road conditions or nighttime driving scenarios. The nighttime driving lighting simulation test will randomly select three items from the project for examination. Candidates only need to use the corresponding lights based on the principle of not interfering with others and ensuring safety. Notes: During the test, there will be voice prompts for light usage, and the operation must be completed within 5 seconds after the voice prompt ends. Do not be slow, but also do not act before the prompt is finished.
