Final answer:
Before turning, drivers should check signal lights, ensure pedestrian safety by watching for people crossing, and observe other vehicles to confirm it is safe to proceed.
Step-by-step explanation:
Before making a turn while driving, it is crucial to check three key things to ensure road safety: signal lights, pedestrians, and other vehicles. Using signal lights is essential to communicate your intentions to other road users. Secondly, pedestrian safety cannot be overlooked as they have the right of way at crosswalks and intersections. It is important to watch for students and others who may need to cross, and a traffic signal can help regulate pedestrian movement to prevent accidents. Lastly, checking for other vehicles includes observing their speed and ensuring it is safe to make the turn without causing disruptions in the flow of traffic. Accidents at intersections can often be attributed to drivers not paying attention to these three critical factors.
