Fleet management allows companies to minimize risks associated with vehicle investment and improve efficiency. It includes purchasing, leasing, maintenance, telematics, fuel management, and health and safety. Preventative maintenance is important to avoid breakdowns and involves regularly checking fluid levels, filters, belts, hoses, and tires. Telematics allows for vehicle tracking, diagnostics, and monitoring fuel usage and driver behavior. Fleet software can help with maintenance records, replacement planning, and warranty tracking. The future of fleets may involve autonomous vehicles with sensors to navigate without human input.
