It is unlawful to possess more than _______ valid Driver License at a time.

The law stipulates that an individual is allowed to possess only one valid driver's license at any given time. This regulation is in place to ensure that identification and driving privileges are clearly associated with a single individual, preventing confusion and potential misconduct that could arise from having multiple licenses. Holding more than one license can lead to complications such as legal issues in case of traffic violations, inconsistencies in driving record histories, and challenges in verifying a driver's identity. This clarity helps law enforcement and other authorities to enforce traffic laws effectively and maintain road safety. Therefore, the correct answer is that an individual may have only one valid driver’s license at a time.
