A dealer may employ persons holding a 90 day certificate...

The correct response regarding the employment of persons holding a 90-day certificate in the context of a dealer’s operation is that this is limited to three certificate holders per place of business. This limitation is likely established to ensure that the workforce is adequately vetted while also maintaining a certain level of professionalism and regulation within the industry. By restricting the number to three, regulatory bodies can better oversee and manage the certifications and ensure that those working under short-term certification are adequately supported and guided by more experienced staff.

This framework also helps in maintaining a standard for the sales process, ensuring that customers receive knowledgeable service without overwhelming a business with untrained or less experienced personnel. Thus, businesses can effectively utilize this temporary certification while still adhering to minimum professional standards.
