Well-rested drivers make safe decisions through: planning and defensive driving delayed reactions and loss of concentration alert observations and quick reactions naps and vitamins

## Step 1<br />The problem is asking us to identify the correct option that represents the characteristics of well-rested drivers. Well-rested drivers are those who have had adequate sleep and are in a good state of mind and body. They are alert, focused, and able to react quickly to any situation on the road.<br /><br />## Step 2<br />Let's analyze each option:<br />- Option A: "planning and defensive driving". While these are good practices for driving, they are not directly related to the state of rest or alertness of the driver.<br />- Option B: "delayed reactions and loss of concentration". These are characteristics of tired or distracted drivers, not well-rested ones.<br />- Option C: "alert observations and quick reactions". These are characteristics of well-rested drivers. They are alert and able to react quickly to any situation on the road.<br />- Option D: "naps and vitamins". While naps can help with rest, they are not a direct characteristic of well-rested drivers. Vitamins can help with overall health, but they are not a direct characteristic of well-rested drivers.<br /><br />## Step 3<br />Based on the analysis, the correct answer is option C: "alert observations and quick reactions".
