Question 19 of 50 you are driving on a public road and need to turn your vehicle around. you can use a three-point turn

The only way you can use the three point turn is when there is a presence of U-turns signs that indicates that it is permitted and another way is when the road that you’re in is narrow enough for the vehicle that would made possible to take a u-turn.

the answer your looking for is c. : )

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
