Why is it important for the driver to estimate a length of 100 feet?

Estimating a length of 100 feet is crucial for school bus drivers primarily to ensure safety and compliance with traffic laws. When approaching a stop or preparing to turn, using the 100 to 300 feet guideline allows the driver to provide sufficient notice to other road users. This early signaling helps prevent accidents by ensuring that vehicles behind the bus have adequate time to react. Additionally, pedestrians, particularly children, who might be around the area will have the opportunity to anticipate the actions of the bus.

Both signal lights and turn signals serve similar purposes in alerting other drivers and pedestrians of the bus driver's intentions. By applying these signals at least 100 feet away from a stop or turn, the driver helps promote a safer environment for students getting on or off the bus, as well as for other vehicles on the road. This practice is rooted in defensive driving techniques that emphasize proactive communication with others on the road to mitigate risks and enhance safety.
