how does the \penny test\ help you assess tire safety?
○ you count the number of pennies you can fit across the tire.
○ you measure the tire’s diameter with a penny.
○ you use a penny to see if lincoln’s head is covered by the tread, indicating sufficient depth.

Explanation:

The Penny Test is used to check tire tread depth. By placing a penny into the tread groove with Lincoln's head facing down, if his head is covered, the tread depth is sufficient; if not, it's too shallow. The third option describes this correctly. The first option is about counting pennies across the tire (not the test's purpose), the second is about measuring diameter (incorrect), and the third matches the Penny Test's use for tread depth assessment.

Answer:

The option: "You use a penny to see if Lincoln's head is covered by the tread, indicating sufficient depth."
