Example Use:
In the Brettonville community, children often waited for their school bus right around a bend in the road, making it difficult for oncoming drivers to anticipate and slow down in time. The town decided to place a 'School Bus Stop Ahead' sign several hundred feet before the bend. After the sign was installed, drivers received advance warning and were able to reduce their speed and approach the area with caution. Consequently, the chances of accidents occurring near the bus stop were significantly reduced. The sign played a pivotal role in alerting unfamiliar or inattentive drivers to the presence of children, ensuring a safer environment for the kids as they waited for their ride to school.
