Final answer:
The special driver certificate is called DL-51, which is a Medical Examination Report for commercial drivers. Options DL-45 and CHP-292 are not the correct forms for the special driver certificate.
Step-by-step explanation:
The special driver certificate you are asking about is DL-51. This is a Medical Examination Report that must be filled out by a licensed physician if you are applying for a commercial driving position in the United States. It is a part of ensuring that commercial drivers maintain a standard of physical health that allows them to drive safely on the roads. The other options, DL-45 and CHP-292, are related to different types of driver licensing and permits, but they are not the special driver certificate itself. To summarize, when referring to a special certificate for drivers, especially in the context of commercial driving, the DL-51 form is the correct designation.
