Read the safety chapter in your automotive text, complete the safety PDF worksheet, take the on-line safety quiz, and then take this safety test. There are five parts to this test. You must get 100% on all five of the test parts, but you have an unlimited number of tries. After completing this test with a 100%, print out the result from the print icon on the test task bar. When you have completed and printed all five parts with 100%, staple them together and turn them in to your instructor.
