Safety is paramount: wildlife (deer, elk) are common at dawn and dusk, especially on US-16. Keep a safe distance, stay alert, and use high beams when possible. Road quality is good, but watch for potholes in spring and sand drifts in winter.

For fatigue management, plan overnight stops at Rock Springs and Lusk. These towns offer affordable motels and quiet environments. Use the rest areas, which are clean and often have vending machines. Take a 15-minute break every 2 hours, stretch, and switch drivers if possible.
