## Frequently asked questions

### What is fleet management?

Fleet management is the set of processes, policies, and tools controlling each vehicle lifecycle: acquisition, operation, compliance, and disposal.

### How to reduce fleet costs?

The three most effective levers: (1) fuel control with fleet card (-15-25% fuel spend), (2) preventive maintenance (-30-40% corrective cost), (3) fleet renewal at optimal depreciation point.

### Is fleet management mandatory in Brazil?

There is no specific legal obligation for private fleets, but the Receita Federal requires proper documentation for fleet expense deduction in Lucro Real.

### What is the cost per km for a service fleet?

Service fleets with sedans or light utility vehicles typically have a CPK of R$ 1.00-1.40/km, including fuel, maintenance, depreciation, and fixed costs.

### When is it worth outsourcing fleet management?

Outsourcing is worth considering when the fleet has grown beyond internal management capacity or when CPK is consistently above market benchmark without identifiable cause.
