Chapter 54. Section 102.3. Section 2.3. Paragraph 12. The rule states that license must be displayed in an appropriate case. A description of the case can be found in the TLC owners manual. Chapter 12. Section 8.2. Sub section 1.4. It states that if you do not have the appropriate case, you may use an appropriate substitute case until your next scheduled inspection. The definition of a substitute case has not be defined. Since there is no official description of a substitute case I recommend fastening your license with duct tape, black would be your best choice of color. If you drive a green cab, mint green tape would also be appropriate. Be careful that the tape does not cover any lettering on your license. If anyone gets a summons for not having an appropriately displayed license, I will be willing to make myself available as an expert witness in a TLC hearing.
