What is the primary purpose of traffic laws?

Answer: B — To ensure safety and efficiency on the road

The primary purpose of traffic laws is to ensure safety and efficiency on the road. Traffic laws are designed to create a structured environment for all road users, including drivers, pedestrians, and cyclists, which helps minimize accidents and injuries. By setting clear rules—such as traffic signals, speed limits, and right-of-way regulations—these laws promote safe driving behavior and help facilitate the orderly flow of traffic. In addition, traffic laws contribute to efficient use of roadways, helping to reduce congestion and making travel more predictable for everyone. While regulating speed limits is one aspect of traffic laws, it is just one component of the broader aim of promoting safety and efficiency overall. Other options, such as collecting revenue through fines or restricting the number of vehicles, may be secondary effects or goals of some traffic measures but do not encapsulate the primary intention of the laws.
