Per a broken file flag submitted by a forum member:

This file has been reported as broken because: I am trying to download the data dictionary for file "100CarEventVideoReducedData_v1_4". Here i only fine the dictionary for v1.3. There are 69 variables in v1.4 data, and only 57 in the v1.3 description.

There are 69 variables in the v1.4 data file as the driver impairment variable was converted from a composite variable to a series of binary (yes/no) variables. The sequence of binary variables in the data file follow the driver impairment sequence listed in the data dictionary (p.45-46), with the 'none apparent' condition indicated when all of the binary driver impairment variables are set to 'no'.
