Factors That Affect Drive Time

• Route choice: Southern routes (I-10) have fewer mountain passes and less winter weather. Northern routes (I-90, I-80) are more scenic but slower.
• Speed limits: Range from 55 mph (urban) to 85 mph (parts of Texas). Average highway speed is 65–75 mph.
• Traffic: Major cities add 30–90 minutes each. Worst: LA, Chicago, Dallas, Atlanta.
• Weather: Winter storms can close mountain passes and add hours of delay. Check conditions for I-80 (Rockies) and I-70 (Colorado).
• Rest stops: Plan 15–20 min stops every 2–3 hours for safety.
• Gas stops: In remote western stretches, gas stations can be 50–100 miles apart.

Tips for a Cross-Country Drive

• Get a full vehicle inspection before departing (tires, oil, brakes).
• Download offline maps – cell service is spotty across Nevada, Utah, and Wyoming.
• Carry a physical atlas as backup.
• Split driving duties if possible.
• Drive during daylight for safety and scenery.
• Book hotels in advance during peak season (June–August).
