The most credible and reliable evidence to support the argument for lowering the age to obtain a driver’s license to 14 years of age is:
A national news broadcast reports that in South Dakota, teenagers as young as 14 years old can receive their restricted driver’s permits.
This piece of evidence is credible because it references a legitimate news source and provides an example of a state where such a policy is already in place. It suggests that there may be a valid precedent for allowing younger individuals to drive, potentially supporting the argument for similar changes in the writer's state.
