An accident in front of a Los Angeles elementary school is once again bringing the debate about driving age to the forefront. A 100-year-old man backing his Cadillac out of a grocery store parking lot struck and injured 11 people, including nine children.

The incident has rekindled a debate: How old is too old to keep driving? Some states require driving tests at a certain age, but should all states require them?

Houston car accident attorneys know that, statistically, teens are by far the riskiest drivers on the roadways. In fact, drivers in their mid- to late-80s have lower crash rates than those in their early 20s, according to the American Automobile Association.
