Final answer:
An inspector/mechanic permit should be prominently displayed in a business area, typically framed under clean glass, to assure customers of the business's compliance with regulations.
Step-by-step explanation:
The question pertains to the display requirements for a professional permit, specifically an inspector/mechanic permit. Generally, such permits should be displayed in a manner that is visible to the public in the place of business where the services are provided. It is a common requirement for business and professional certifications to be framed under clean glass and displayed in a prominent area such as the waiting room or reception of a service station, garage, or inspection facility. This practice serves to assure customers that the business operates under the required regulations and its employees are properly certified. As regulations can vary by jurisdiction, any mechanic or inspector should verify the specific display guidelines set forth by their local or state regulating body.
