+  High Speeds = Higher Fuel Bills
According to the U.S. Department of Energy, fuel consumption increases almost 2% for each mile per hour above 50.
55 mph = 7% in increased fuel costs
60 mph = 14% in increased fuel costs
70 mph = 23% in increased fuel costs
80 mph = 34% in increased fuel costs

+  Long Idling = High Fuel Loss
According to the U.S. Department of Energy, running a vehicle at idle speed dramatically reduces engine life. One hour of idle time is equal to using one gallon of gas. Excessive idling can waste up to 800 gallons of fuel annually for the average truck.

+  No Oversight = Excess Overtime
Inefficient routes, unscheduled stops and unauthorized trips can lead to serious overtime costs. With a GPS Fleet Management system in place a manger can take the appropriate steps needed to deal with route inefficiencies and off-route activity that can lead to a longer work day and excessive overtime costs.

+  Effect on Maintenance Costs
Gears, bearings, clutches, suspension, and drive trains all wear much faster at higher speeds. Increasing speed from 50 MPH to 60 MPH increases maintenance cost by 38%. Increasing the speed to 70 MPH increases the cost by 80%.

+  Effect on Tires
Heat is the number one enemy of tires. Sustained high speeds raise tire temperatures above the critical level causing strength and wear properties to deteriorate rapidly. Tire wear will almost double at road speeds of 70 MPH or greater.

+  Effect on Accident Probabilities
Approximate stopping distances, including reaction time for the average person (2 axle trucks) are listed below:
@ 50 MPH 275 feet (.92 football fields)
@ 60 MPH 375 feet (1.25 football fields)
@ 70 MPH 500 feet (1.67 football fields)
