How far could the blind spot extend behind a school bus?

The blind spot behind a school bus is significant due to the size and height of the vehicle, which can obstruct a driver's view of smaller vehicles and pedestrians. It is established that the blind spot can extend roughly 400 feet behind the bus. This information is crucial for bus drivers, as it emphasizes the necessity of being vigilant when backing up or changing lanes. Knowledge of the blind spots helps in reducing the risk of collisions and ensuring the safety of students boarding or alighting from the bus, as well as other road users. Understanding this distance can aid drivers in making informed decisions while operating a school bus and maintaining awareness of their surroundings.
