What has to be in the Driver Investigation History file?
The file must contain all records related to the investigation into the safety performance history of new or prospective drivers. The file must be maintained in a secure location with controlled access. At a minimum, the file must include the following: a copy of the driver’s written authorization for the employer to seek information about the driver’s drug/alcohol history; a copy of the response(s) received from each previous employer, in writing, including the previous employer’s name and address, the date of contact, and the information received about the driver; and documentation of failures to contact a previous employer, or the employer’s failure to provide the required information.
