Final answer:
A steady lighted red arrow pointing left at an intersection requires that vehicles turning left must stop and wait for a green arrow signal for safety and speed control.
Step-by-step explanation:
At an intersection of two two-way streets, a steady lighted red arrow pointing left means that vehicles turning left must stop and wait for a green arrow signal. This traffic control device is designed to ensure pedestrian safety and vehicle speed regulation, as pedestrians crossing the intersection are given time to do so safely, and vehicles are prevented from speeding through. Having a red arrow signal reduces the likelihood of accidents, which justifies the installation of such traffic signals.
