Final answer:
The answer is generally true; drivers on a one-way street can typically turn left on red onto another one-way street, but local laws may differ. Traffic signals help manage speed and ensure pedestrian safety, with allowances for special circumstances.
Step-by-step explanation:
The answer to the student's question is true: After making a proper stop and yielding to all traffic and pedestrians within the intersection, it is generally permissible for drivers on a one-way street to turn left at a red light onto another one-way street that moves traffic to the left; however, this is subject to state and local traffic laws, which may vary.
The installation of a traffic signal at problematic intersections can greatly improve safety for both pedestrians and drivers. For instance, pedestrians, such as students navigating campus intersections, benefit from signals that regulate crossing times, while drivers are forced to slow down and adhere to speed limits, thus reducing the possibility of speeding accidents. Furthermore, in emergency cases, such as with a vehicle transporting an individual in labor to a hospital, different rules may apply that balance legal adherence with urgent need. Ultimately, traffic signals are installed as an effective measure for controlling speed, ensuring pedestrian safety, and managing the flow of traffic efficiently.
