Ron Davis was laid off by RCA, a corporation taken over by G.E., where he had worked for years. At a loss, a friend told him, If you have a drivers license, you should never be without a job especially if you keep a clean record. This is a suggestion he heeded and passes on to others now through his workbook of practice tests for commercial drivers licenses (CDL) exams. The tests covered in Ron Daviss CDL Workbook include: general knowledge, air brakes, combination vehicles, passenger transport, hazardous materials, tanks, and double/triple trailers. A Bus Drivers Bonus is included, offering a well-rounded review of typical examination questions.
