Two of the three Es of driving are enforcement, education, and what?

The correct answer is engineering. The "three Es" of driving—enforcement, education, and engineering—represent key elements in promoting safe driving practices and improving road safety.

Engineering refers to the design and maintenance of roadways, traffic control devices, and vehicles. This aspect includes creating safe road layouts, ensuring that signs and signals are clear and effective, and that vehicles are built to meet safety standards. Through thoughtful engineering, the incidence of accidents can be minimized, ultimately leading to a safer driving environment for all users.

The other components, enforcement and education, complement engineering. While enforcement focuses on ensuring compliance with traffic laws and regulations, education aims to increase awareness and understanding of safe driving practices among the public. Together, these three elements work synergistically to enhance road safety, making engineering a critical component in this framework.
