Interstate 5 provides a smooth, well-maintained highway for the majority of the trip. Expect consistent road quality with periodic construction zones in urban areas. The route is toll-free, with no notable tolls.

Fuel costs vary significantly: California averages $4.50/gallon, Oregon $3.80, and Washington $4.00. Plan for about 25 mpg, translating to roughly $100 in fuel for the trip. Gas stations are plentiful along I-5, with clusters every 30-50 miles in rural stretches.

• Major rest areas: Shasta Valley (mile 23), Rogue River (mile 99), and Lewis River (mile 21).
• Oregon has no self-serve gas; attendants pump for you.
• Speed limits: 65 mph in California, 65-70 mph in Oregon, 60-70 mph in Washington.

Weather varies drastically: snowy passes in California and Oregon during winter, and warm, dry summers. Always check forecasts and carry chains if traveling between November and March. The route includes several steep grades, notably the Siskiyou Summit (elevation 4,310 ft) near the Oregon border.

For families, the drive offers numerous kid-friendly stops: the Oregon Zoo in Portland, the Children's Museum of Tacoma, and numerous parks with playgrounds. Many rest areas have picnic tables and pet areas. Leashed pets are allowed at most rest stops, but keep them in the car at busy periods.

To manage fatigue, plan a break every 2-3 hours. The route has safe, well-lit rest areas, but avoid overnight parking unless designated. Consider using apps like Wayro's how to find the best stops and hidden gems between cities to discover lesser-known spots.
