An employer can ask about a driver’s license if driving is an essential part of the job. Applications for these jobs may include a statement about the need for successful candidates to prove they have a valid driver's license. The statement could say something like: • I understand that if this position requires a valid driver’s license, proof will be required after hire, or • Some positions require the successful candidate to have a valid driver's license. The successful candidate would have to provide proof that s/he has a valid driver's license when offered employment. It is permissible to ask for an applicant's driver's license number in order to facilitate a job-related background check. However, a company should consider obtaining such information as late in the application process as possible, in order to minimize the amount of confidential information it obtains.
