CDL Test/Practice Pad Dimensions

We’ll help you determine the total length and cone placement of a CDL Practice pad. Your pad should have room for all 4 backing maneuvers. You'll start with 3 lines painted on a hard surface. Each line is 100'long. The distance between each line is 12’. You’ll place cones on each line every 10’. Check out our CDL Backing Lessons to help you gain perspective before you start to use your CDL Practice Pad.

A CDL Test Practice Pad must fit four maneuvers:

Space Saving Configuration

The first three maneuvers are neatly contained in a 100’ long x 24’ wide box. You need some extra space for the truck to pull through. See the table below for the total area needed.
