The end terminals and crash cushions shown in the table below have been classified into five groups: Types A, B, C, D and E. This classification is used by MoDOT for specification purposes and does not reflect any national standard. Descriptions of the categories may be found in MoDOT’s Engineering Policy Guide (EPG). Sand Barrels are listed as a separate category, as are workzone devices, cable barriers, and miscellaneous hardware.
