What is the recommended speed before shifting into number 2 gear?

Shifting into number 2 gear is typically recommended at around 10 mph because this speed allows for optimal engine performance and control of the bus while maintaining power as the vehicle transitions through the gears. At this speed, the engine is not under too much strain, and it allows for smoother handling and better fuel efficiency. It is crucial for bus drivers to understand the appropriate speed for gear changes, as doing so ensures safety and proper function of the vehicle. Speeds that are too low may not provide enough momentum for a smooth shift, while higher speeds can cause undue stress on the transmission and result in rough shifting.
