“We have discovered some fascinating statistics that will continue to help businesses up and down the country, by showcasing the slowest motorways nationwide.”

Each tracking device records the geo-location of the vehicle and the speed of the vehicle.

McClellan continued: “RAM Tracking allows fleet managers to make decisions backed by powerful data to save them vital money on fuel consumption as well as boost productivity.”
