How many feet in advance should a school bus turn signal be engaged before making a turn?

Engaging the turn signal 300 feet in advance before making a turn is essential for providing adequate notice to other road users, particularly in the context of safely transporting students on a school bus. This distance allows drivers behind or approaching the bus to be aware of the bus's intention to turn, contributing to overall road safety. It ensures that other vehicles can react appropriately, reducing the likelihood of confusion or accidents.

This practice is also part of the regulations governing school bus operation, which emphasize the safety of children when boarding or disembarking from the bus. By signaling well in advance, bus drivers give both drivers and pedestrians enough time to adapt to the bus's movements, thus enhancing the safety of all parties involved.
