Infrastructure Safety & Road Quality

Both states require seat belts and child car seats. Speed limits: 65-70 mph on I-5, 55 mph on OR-6. Oregon has no self-service gas—attendants pump for you, which can delay refueling. Keep an emergency kit with water, blankets, and a flashlight.

• Emergency numbers: 911; Oregon State Police (800-452-7888).
• Roadside assistance: AAA covers both states.
• Cell service: Gaps on OR-6 (Verizon has best coverage).

Fatigue Management & Rest Zones

Long stretches on I-5 can cause highway hypnosis. Take breaks every 100 miles. Use the “20-20-20 rule”: every 20 minutes, look 20 feet ahead for 20 seconds. Caffeine helps but avoid heavy meals. The safest rest areas are the “Safety Rest Areas” with 24/7 patrols—these exist at mile markers 430, 560, and 720 on I-5. On OR-6, the Tillamook State Forest has designated pullouts with restrooms.

• Strategic rest stops: Corning (MM 630) has a massive travel plaza with Starbucks.
