CFME for light trucks is now available from a number of sources. Installing the CFME under the truck facilitates parking. Mounted on the tow-hitch however, the equipment can be easily serviced or temporarily removed from the truck many times throughout the winter months.
IceChek produces an under-truck model (right wheel track) as well as several tow-hitch models. While we refer to the rear-mounted models as "tow-hitch models", a second connection point is required in addition to the hitch receptacle. This second connection is achieved with custom-built brackets.
- Consistency or "reproduce-ability" in repeated test runs over the same stretch of highway. We suggest exporting a file of readings into a spreadsheet program and creating an X-Y line graph as a simple means of comparing data. The average reading between any two geographical points on the test run should be close (within a few percentage points) in repeated test runs.

- Well-defined graphs at the beginning and end of icy patches on the highway are also important.
- The delay between the time the testing vehicle passes over a point on the road and the time that the actual friction measurement for the point is displayed. The readings must correspond to the new friction level or approach the new friction level within a few seconds.
- To determine the general accuracy of any equipment, compare CFME measurements with data obtained on the same surface in braking tests using a decelerometer. If you do not have access to a decelerometer, you can measure stopping distance with a tape measure the old-fashioned way.
- Will the equipment be practical for hundreds of kilometers each day, all winter long?
