This study involved four parts: (1) a literature review on the current research of the risks of older drivers and associated data; (2) an analysis of Motor Carrier Management Information System (MCMIS) data to retrieve crashes and Commercial Driver's License Information System (CDLIS) data to retrieve driver age; (3) a data collection and analysis of carrier crash records, driver age, critical reason assigned to the crash, and vehicle miles traveled; and (4) an assessment of the need for a performance-based test. |
