The research team procured a dataset from a third-party provider (TPP) that included all vision-related data obtained during Department of Transportation (DOT) medical examinations for nearly 200,000 CMV drivers from six carriers. This data was merged with crash records from the Motor Carrier Management Information System (MCMIS) provided by FMCSA. Note that the MCMIS dataset does not include information on driver fault or the cause of the crash.88
