What precaution should be taken when loading students onto a bus?

When loading students onto a bus, ensuring that traffic has stopped is a critical precaution for several reasons. First and foremost, the safety of the students is the top priority. When traffic is stopped, it creates a safe zone around the bus, preventing vehicles from approaching and reducing the risk of accidents.

This practice allows students to load the bus without the distraction or danger posed by oncoming traffic, which can be unpredictable and fast-moving. Additionally, this precaution helps to instruct other drivers about the situation, alerting them to the presence of children and the need to exercise caution.

Other options, such as having students sprint to the bus or allowing them to board while the bus is in motion, would introduce unnecessary risks and hazards. Entering in a single file, while generally a good practice for organization, does not address the significant safety concern related to active traffic. Thus, ensuring that traffic has halted is the primary measure that must be taken to promote a safe loading environment for students.
