BLACKSBURG, Va. -

A recent DMV study shows Virginia is out of line with other states when it comes to re-testing older drivers. The study cites a dozen states that have no restrictions for older drivers. But 19 other states have an average cut off age of 71.

They never met a firecracker by the name of Marguerite Overton.

Standing all of five feet tall, Marguerite Overton adjusted the front seat of her 2004 van as far up as it would go.

"As you can see I have short legs, short everything,” Overton said.

Mrs. Overton doesn't look like it, but she's 88 and as sharp as any knife in the drawer. She’s been driving for some 60 years.

Some Virginia lawmakers think older drivers, like Marguerite, should be tested more often if they want to renew their license.

Currently, when Virginia drivers turn 80, they must re-apply in person to renew their license and take a vision test. A new bill would require the same thing, but at 75.

Between 2003 and 2012, federal officials say the number of licensed drivers 65 and older grew to 35 million.

During that same time, 214,000 accidents involved older drivers.

I asked Mrs. Overton, "Is it harder for you to judge distance or is your eyesight pretty doggone good?"

"My eyesight's good thank goodness,” Overton said.

As we cruised through Blacksburg, I asked Mrs. Overton if she had friends, older drivers who shouldn't be driving. I asked her to be honest.

With her eyes fixed on the road, she said, "You're not going to get me to name them are you? haha!"

Many older drivers don't want rules changed that could take away or limit their driving privileges.

Mrs. Overton said she's no different.

"No one wants to give it up. Nobody wants to give up independence that we do not have otherwise,” she said.

Mrs. Overton turns 89 in April and says shes got no problem getting re-tested to renew her license, but don't base it only on age.

Lawmakers say they don't expect the rules to change this year.
