What the data shows
Caltrans District 11’s Q1 2026 Operations Report logs incidents that block traffic lanes or require CHP response on state freeways. Stranded-EV incidents — where the driver ran out of charge or a 12V fault disabled the vehicle — hit 847 for the quarter, a 34% year-over-year jump from Q1 2024.
Three takeaways:
- I-5 north of Carlsbad is the #1 corridor. Between Carlsbad and the I-15 junction, DC fast charger density is thinner than SD metro — drivers traveling to OC / LA with low state-of-charge hit empty here more often than anywhere else in the region.
- I-8 east of El Cajon is #2. Alpine, Pine Valley, and the approach to the Cuyamaca mountains are effectively a DC fast charger desert beyond Alpine. Drivers underestimate the climb into backcountry + headwind.
- Model Y + Mach-E are overrepresented. Per Caltrans’ incident codes, Model Y accounts for 28% of EV incidents (matches SD County’s ~30% Tesla market share), but Mach-E accounts for 15% despite being under 5% of EV registrations — likely reflecting higher-mileage road-trip use and less-accurate range estimation.
Why this matters if you drive a non-Tesla EV in SD
Two practical implications:
- Plan your state-of-charge before leaving metro. A Mach-E or ID.4 heading to OC via I-5 should leave SD with 60%+ SOC, not 40%. Highway speeds + coastal headwind + HVAC load cut real-world range by 20-30% vs EPA estimates.
- Know your rescue options. If you do get stranded, Charge Pro dispatches across all of SD County including I-5 + I-8. AAA’s EV rescue service is available but has longer response times and non-native dispatch (flatbed tow to nearest charger) rather than on-scene rescue charge.
How Charge Pro’s coverage matches the data
Our fleet coverage is tuned to where the incidents actually happen. Median response times by corridor:
- I-5 metro to I-15 junction: 25-35 minutes
- I-8 El Cajon to Alpine: 35-45 minutes
- I-15 to Escondido: 30-40 minutes
- Backcountry (Julian, Borrego): 60-90 minutes (dedicated route, not same-day guaranteed)
Next steps
Save our dispatch number now — (858) 808-6055 — so it’s ready if you need it. Our emergency EV roadside page covers the full coverage area. Faster than flatbed tow, cheaper than running out on the Grapevine.
