Step 3: Navigate the Primary Route via Highway 78

Troubleshooting Common Drive Issues
If Roads Are Closed Due to Weather
Solution: Check CalTrans real-time navigation updates. Winter storms occasionally close Banner Grade (S-22) due to ice. Highway 78 remains open year-round except during extreme flash flooding (rare, typically August-September monsoon season).
If You Run Low on Fuel
Solution: Ramona offers the last major fuel stops before the 40-mile desert stretch. Emergency roadside assistance has limited availability in backcountry roads. Carry extra fuel if vehicle gets under 15 MPG.
If Cell Coverage Drops
Solution: Cell phone service on road to Borrego Springs is intermittent after Ramona. Download offline maps before departure. Verizon and AT&T provide best coverage; T-Mobile and Sprint have significant gaps.
If Vehicle Overheats in Summer
Solution: Summer heat in Borrego Springs regularly exceeds 110°F (June-September). Turn off air conditioning during steep Banner Grade ascents. Allow engine to cool at Scissors Crossing rest area if temperature gauge rises.
