California Class C Drivers Practice Test

The primary purpose of a speed bump is to slow down traffic. Speed bumps are typically installed in areas where it is crucial to reduce vehicle speed to enhance safety, particularly in residential neighborhoods, near schools, and in parking lots. They serve as a physical deterrent to speeding by creating a momentary obstacle that drivers must navigate carefully, thereby encouraging them to reduce their speed. This design is effective in minimizing the risk of accidents and improving pedestrian safety. While speed bumps can indirectly indicate slower traffic zones and improve safety for pedestrians, their main function is to compel vehicles to slow down. Other options may relate to different aspects of road design or safety but do not directly align with the primary intent of a speed bump.
