How many seconds before departing a school must the engine of the bus be started?

• A. 10 seconds
• B. 20 seconds
• C. 30 seconds
• D. 60 seconds

Answer: (C)

Starting the engine of the bus at least 30 seconds before departing from a school is essential for ensuring the safety and readiness of the vehicle. This timeframe allows the engine to warm up, which is important for proper operation, especially in colder weather. A warmed-up engine operates more efficiently, delivering better performance and enhancing safety.

Additionally, starting the engine early allows the driver to conduct a pre-departure check, ensuring that everything is functioning correctly before the bus enters traffic. This practice also provides time for any issues to be addressed and confirms that safety features like lights and signals are operational. By allowing this time, the driver can ensure a smooth and safe departure, which is crucial for the safety of the students being transported.
