The most credible and reliable support for the argument in favor of lowering the age to get a driver’s license to 14 years of age would be:
A national news broadcast reports that in South Dakota, teenagers as young as 14 years old can receive their restricted driver’s permits.
This evidence is credible because it refers to an established law in another state, reflecting a practical example of a similar policy. It also suggests that this practice has been deemed acceptable and potentially successful, providing a concrete basis for the argument rather than personal anecdotes or opinions.
