Fleet managers are increasingly willing to invest in technologies that can lower operating costs. Regulation compliance, total cost of ownership, and driver retention are top concerns. Advanced safety technologies like collision mitigation systems and stability control are expected to see increased adoption. Telematics services like prognostics are growing in popularity due to their potential for cost savings. Natural gas and smaller diesel engines are gaining interest from some fleets. Overall, fleet managers prefer technologies that enhance productivity, safety and regulatory compliance while controlling expenses.
