Final answer:
Yes, the statement is true. Obeying school crossing guards is essential for maintaining pedestrian safety and ensuring an orderly traffic flow.
Step-by-step explanation:
The statement 'You must obey instructions from school crossing guards?' is true. School crossing guards play a critical role in pedestrian safety, especially for students who are crossing streets on their way to and from school. It's important to obey their instructions for your safety and to ensure traffic flows smoothly without any accidents. For instance, when a traffic signal is implemented at a busy intersection, it allows students to cross at designated times rather than needing to navigate moving traffic, significantly lowering the risk of an accident.
