Final answer:
To make a left turn from a one-way street, position your vehicle close to the left-hand side of the roadway to follow traffic rules and ensure safety. Traffic signals are essential for controlling vehicle speed and supporting pedestrian safety at intersections.
Step-by-step explanation:
Before making a left turn from a one-way street, you should position your vehicle close to the left-hand side of the roadway. Being on the left side allows other drivers to anticipate your actions and ensures you are following road rules which are important for traffic flow and safety. When turning, it is always crucial to signal your intention well ahead of the turn to notify other road users of your planned maneuver.
Regarding road safety, traffic signals play a significant role. They can effectively slow down speeding vehicles, as drivers must stop or yield when approaching the signal. Signals also enhance pedestrian safety by providing designated crossing times and reducing the need for pedestrians to dodge traffic, which is particularly important in areas with high foot traffic such as school campuses.
