Final answer:
The answer to the Smith Driving System key is to make sure others see you, which is not one of the options provided. This principle supports visibility while driving, contributing to overall safety. Enforcement of traffic laws, like speed limits and seat belt requirements, is important for maintaining safe driving conditions.
Step-by-step explanation:
One of the five keys to the Smith Driving System is: Make sure others see you. This principle is crucial for safe driving and ensuring that you are visible to other drivers to avoid accidents. None of the provided options (follow the speed limit, drive defensively, wear seat belts, obey traffic signs) directly relate to this key of being seen by others. Making sure others see you involves using turn signals, headlights, and positioning on the road in such a way that other drivers are aware of your presence.
Driving behavior is greatly influenced by awareness and enforcement of rules. For example, the presence of a traffic signal typically causes drivers to slow down as they approach an intersection, rather than speeding through with no regard for the posted speed limit. Furthermore, government regulations, like mandatory seat belt laws, are in place to protect the citizens by reducing the number of severe injuries in accidents and the subsequent care costs that society must bear.
Ultimately, driving safely encompasses a range of behaviors including adhering to road rules, being aware of other road users, and taking proactive steps to ensure one's visibility to others, thereby reducing the risk of accidents.
