In what way do traffic laws save lives?

Traffic laws save lives primarily through the enforcement of consistent driving behavior. These laws are established to create a predictable and safe driving environment for all road users. When drivers adhere to established regulations such as speed limits, yielding at intersections, and using turn signals, it leads to reduced confusion and fewer accidents. Consistent driving behavior helps prevent risky maneuvers that can lead to collisions, thereby enhancing overall road safety for both drivers and pedestrians.

The other aspects mentioned in the other choices do not contribute to safety in the same way. Increasing the number of cars on the road can lead to congestion and a higher likelihood of accidents rather than safety. Disdainful attitudes toward traffic laws can result in dangerous driving practices, undermining the very purpose these laws serve. While regulating vehicle types may impact road safety, it is the consistent adherence to traffic rules that directly influences driver behavior and safety outcomes.
