18. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you

20. When is it appropriate to use cruise control?
Show answer
Answer B: On a dry, open highway with light traffic

A properly worn belt protects both mother and baby. The lap portion goes low under the belly, snug across the hip bones, and the shoulder belt crosses between the breasts.
-
24. Halfway through a curve you realize you are going too fast. What is the best response?
