Question 1: When a motor carrier receives a request for driver information from another motor carrier about a former or current driver, is it required to supply the requested information?
Guidance: Generally no. See §382.405, however, for requests pertaining to drug and alcohol records.
Question 2: May motor carriers use third parties to ask State agencies for copies of the driving record of driver-applicants?
Guidance: Yes. Driver information services or companies acting as the motor carrier’s agent may be used to contact State agencies. However, the motor carrier is responsible for ensuring the information obtained is accurate.
