The car pass rate.

The pass rate is a key indicator of maintenance efficiency. A high rate means the car is well maintained and reduces the risk of technical problems.

Factors affecting the pass rate

  • Car age: Old cars have a lower pass rate.
  • Maintenance: Well-maintained = high rate.
  • Car type: Heavy trucks have more problems than small ones.
  • Road conditions: The roads are poor, deterioration is low.
  • Driving behavior: Driving too hard can cause a quick breakdown.

The cost of failing to check.

The total cost of falling checks consists of:

  1. Fixed the problem found in the check.
  2. Retest
  3. Downtime damage.
  4. There may be a fine in case of serious deterioration.

Regular maintenance and a targeted pass rate of 90% or higher will reduce costs and increase efficiency in the management of company vehicles.
