Final answer:
A motorist should use the left turn signal, yield to oncoming traffic and pedestrians, and wait for a safe gap before turning at an intersection. Additionally, traffic signals at intersections enhance overall safety for both motorists and pedestrians.
Step-by-step explanation:
When making a left turn at an intersection, a motorist should do the following: Use the left turn signal and move into the left lane, yield to oncoming traffic and pedestrians, and wait for a safe gap in traffic before turning. This comprehensive approach ensures the motorist complies with traffic laws, prioritizes safety, and minimizes the potential hazards associated with intersections. Notably, the establishment of a traffic signal at problematic intersections can significantly improve safety by regulating vehicle speeds, providing safer crossing for pedestrians, and reducing the occurrence of accidents, which in some tragic cases may result in a loss of life.
