A single interchange connects Port Orange to I-95: Exit 256 at Dunlawton Avenue, SR 421. The city also lends its mailing address to the Tomoka Landfill, Volusia County’s 3,400-acre disposal site on Tomoka Farms Road, which takes garbage, construction and demolition debris, yard waste and every kind of tire. Between the interstate, the landfill traffic and Nova Road starting at US 1, Port Orange sees a lot of heavy trucks. None of RDI Power’s facilities are in Port Orange; the only shop is in Brooksville. Our technicians come out from Brooksville with diagnostic tools and on-site repair capability to yards, job sites and roadsides across the city.
Exit 256 and Dunlawton Avenue in Port Orange
FDOT’s 2025 counts show about 13,275 trucks a day on I-95 through Port Orange and about 3,674 on SR 421, where trucks make up 16.7% of traffic. When a truck stops near the interchange, the first detail we need is which road it is on: the I-95 mainline, a ramp, or Dunlawton Avenue east or west of the interstate. On I-95, add the direction and a mile marker. On Dunlawton, the nearest cross street or business will do.
If the truck still moves, a side street or lot off Dunlawton gives the technician a far safer workplace than the curb lane. On the interstate, get as far onto the shoulder as it will go and stand well away from traffic. Give us the year, make and engine too, and what the dash showed before it quit; a photo of the warning lights taken before you shut the engine off can save real diagnostic time.
Trucks bound for the Tomoka Landfill on Tomoka Farms Road
The landfill is projected to stay open until about 2052, so the trucks that haul garbage, debris, yard waste and tires to it are not going anywhere. A breakdown on the way in or inside the site is a job-site call. Tell us who to check in with, where in the site the truck sits and whether it is loaded, because a full body changes what can safely be done and where. Soft or uneven ground limits what the technician can do safely; if the truck can still move to firm, level ground, move it.
Nova Road from its south end in Port Orange
Nova Road, SR 5A, begins at US 1 in Port Orange and runs 15.6 miles north through South Daytona, Daytona Beach and Holly Hill to Ormond Beach. Near Port Orange it carries about 1,647 trucks a day, and US 1 about 2,015. Florida East Coast Railway freight trains also pass through the city without stopping. A truck that stalls at a crossing is a different kind of emergency: get everyone out and well clear first, then call the number posted on the blue sign at the crossing before you call anyone else.
Port Orange fixes the technician can finish on site
The technician diagnoses before replacing anything, using Ford IDS on Power Stroke trucks, WiTECH on Ram and heavy-duty software on tractors and vocational trucks. Common on-site work includes:
- Starting and charging faults: batteries, cables, grounds, starters and alternators
- Air brake problems: leaking lines and fittings, brake chambers and slack adjusters
- Fuel delivery: plugged filters, water in the separator, air in the system
- Electrical: failed sensors and damaged harnesses behind derates or shutdowns
- Cooling: belts, hoses and leaks the technician can reach
- Aftertreatment: DEF faults, and parked regenerations where the system allows one
A safe workplace makes all of that possible. The best spot is paved or hard-packed and level, with room to walk around the truck and park the service truck beside it. Have the keys ready, open any gates, and keep someone available who knows the truck’s recent history. The finished job is recorded on a digital inspection with photos and the technician’s notes.
Port Orange work that goes to Brooksville
Some jobs need the shop: internal engine work, transmission rebuilds and anything that requires a lift or heavy tooling. When the diagnosis points that way, we lay out the options and plan with you how and when the truck gets to Brooksville, so the downtime is something you can schedule around. The on-site diagnosis goes along, and the shop starts where the technician left off. Labor carries a 3-year / 36,000-mile warranty, or the 2-year / 24,000-mile fleet warranty on RDI Fleet accounts.
Describing a Port Orange breakdown over the phone
Fleet customers have 24/7 roadside assistance. Anyone else can call (352) 433-3800 between 7:00 AM and 4:00 PM, Monday to Friday. Since technicians come from Brooksville, you will hear a realistic estimate of when one can reach Port Orange, not a promise designed to end the call.
Fleets that want fewer of these calls can read Port Orange fleet maintenance. Trucks stopped farther up Nova Road are covered on our South Daytona mobile diesel repair page, and the whole program is explained under mobile diesel repair.
