What must you remember in regular traffic?

Your answer is correct because, in regular traffic, it is important that the destination and route signs display accurate information so passengers and other road users know where the bus is heading. Additionally, the bus line number must be visible on the rear of the bus to clearly identify the service for following vehicles and passengers. The third option is incorrect because destination and route signs are generally allowed to be lit during driving, not only when stopping. Understanding these rules helps ensure clear communication and safety in public transportation.
