Fleet Repair and Maintenance

Preventative Maintenance

We are industry leaders when it comes to maintaining our buses to ensure passenger safety. Our safety begins with safe vehicles.

Our school district partners benefit from our recognized preventive maintenance program. Our preventive maintenance schedule goes above and beyond government requirements. Every school day, our drivers do a multi-point inspection before and after each route to check for maintenance issues that need immediate attention. The Ministry of Transportation requires a minimum of a Level 1 Inspection and a Level 2 inspection on an annual basis. Attridge far exceeds this standard with 3 Level 1 inspections and 2 Level 2 inspections annually. All inspections include examining everything from cosmetic issues to checking tires, brakes, engine performance and suspension.

Maintenance Software


The preventative maintenance program is guided by schedules and inventory maintained using our fleet management software. Our flexible fleet software connects; accounts, preventative maintenance, fleet cost, inspections and tire control with interfaces that allow parts management and ordering. The software permits the user to produce daily, weekly and monthly reports that schedule regular service from oil changes through safety inspections. The Preventative Maintenance Coordinator can then schedule, with the assistance of the Shop Foreman, mechanics and buses through one of our five repair facilities in order to ensure the highest level of repair and maintenance.

Vehicle Maintenance


Vehicle maintenance in combination with an excellent driver results in a safe, reliable and successful school bus service.

Vehicles are maintained in accordance with manufacturer recommendations and requirements. Our preventive maintenance program meets and exceeds state and federal inspection requirements. In addition, we follow our company’s own preventive maintenance program, which includes:

  • No bus leaves the lot to pick up students without the driver having first completed a multi-point, pre-trip inspection that documents any safety or maintenance issue—no matter how small—and clears the bus for travel. Critical issues are reported to our service center and a team of highly trained mechanics is dispatched to make repairs.
  • Many of our buses are equipped with technology that constantly monitors the vehicle’s operating condition, sending real-time data back to our dispatchers, who ensure that no critical issues put the safe operating condition of the bus at risk.
  • Our drivers have the freedom to escalate any maintenance issue to a critical level—providing a check-and-balance to ensure that no bus is on the road with an issue, which could lead to a breakdown and inconvenience student passengers.

Each of our buses is scheduled for a regular preventive maintenance inspection according to hours of operation, kilometers traveled, or days operated, depending on the type of operation and service being provided.

Fleet Inspection Program


  • Periodic Motor Vehicle Inspection (Level 1) every 180 days – This is a full annual safety including all components as detailed in Regulation 611 of the Highway Traffic Act. The MTO is proposing changes to the commercial motor vehicle inspection criteria to adopt the National Safety Code for trucks and buses. Attridge Transportation inspections will meet this proposed standard.
  • Visual safety inspection every 120 days – The Ministry of Transportation requires a minimum of a Level 1 Inspection and a Level 2 inspection on an annual basis. Attridge Transportation far exceeds this standard with 3 Level 1 inspections and 2 Level 2 inspections annually.
  • Schedule 4 Maintenance every 30 days or 12,000km – It consists of a detailed under-vehicle inspection and a copy must be kept in the vehicle. This inspection covers the brakes, frame, suspension and under-vehicle components which cannot be viewed from when the bus is on the ground.
  • Daily Pre/Post Trip Inspections on all Vehicles – The purpose of the daily vehicle inspection is to ensure that problems and defects have been identified before the vehicle is operated on the highway. Inspections prevent the operation of a vehicle with problems that are likely to cause or contribute to the severity of an accident.
