24/7 Emergency Roadside Assistance

Breakdowns don’t follow a schedule, and when a truck or RV goes down, every minute matters. California Mobile Fleet provides 24/7 emergency roadside assistance designed to get you moving again as quickly and safely as possible.

Our fully equipped mobile service trucks  respond directly to highways, job sites, fleet yards, and remote locations throughout Southern California. Whether you’re dealing with a mechanical failure, warning lights, drivability issues, or an unexpected breakdown, our technicians arrive prepared to diagnose the problem on-site and perform immediate repairs whenever possible.

When towing is required, we coordinate safe and efficient transport to minimize downtime and protect your equipment.

This mobile-first emergency service is ideal for semi-trucks, big rigs, fleet vehicles, and RVs, giving owner-operators, fleet managers, and travelers peace of mind knowing professional help is always within reach.

Our technicians work around your schedule, providing consistent, professional service wherever your vehicles are located, so downtime is kept to a minimum and productivity stays high.
