Case Study: Dee Bus Service achieves faster repairs, reduced maintenance costs and improved student safety with Zonar Systems

Safer students, healthier buses, thousands in yearly savings: This contract school bus fleet has it all

Dee Bus Service, Inc. is a family‑owned pupil transportation contractor serving 57 school districts across three counties in the Boston/Metrowest area with 238 school buses and 130 special‑needs vans spread over a 50‑square‑mile operating area. Because vehicles are parked at district lots rather than a central depot, DBSI struggled with limited fleet visibility, paper DVIRs that delayed repairs up to two weeks, recurring dead‑battery incidents, higher towing and repair costs, and burdensome physical record storage.

DBSI implemented Zonar’s smart fleet stack — Ground Traffic Control, V4 and LD TCUs, EVIR electronic inspections, Galaxy Tab Active3 tablets and RAM mounts — to enable real‑time location, remote diagnostics and instant, digital DVIRs. The result: inspections and repairs now occur within 24–48 hours, more than $7,000 a year saved on DVIR books, near‑zero towing fees, fewer major repairs and roadside transfers, improved battery and brake management, streamlined maintenance workflows and better student safety and asset resale value.
