PALM DESERT, Calif. -

How old is too old? That's the big question when it comes to getting behind the wheel.

"I think it depends on the person," said Coachella Valley resident, Larry King. "I've seen people in their 50s and 60s that are horrible drivers."

But, it isn't until the age of 70 that people have to take extra measures to keep their drivers license.

"When you are 70 years or older if you go to the DMV to renew your license you can no longer do it through the mail you actually have to go in, take a test and do a vision test," said California Highway Patrol Officer, Mike Radford.

Radford teaches a class to help seniors ages 65 and older drive safe.

"It's a program the California Highway Patrol has all over the state," he said. "It's called 'Age Well, Drive Safe' and we basically talk about when to limit or stop driving."

It's a question many find tough to answer.

"We have the ability to do a priority re-evaluation so if we determine based on their driving or our interaction with them -- they're confused, they can't answer certain questions the right way -- we can actually take their license and then they're required to go to the DMV for tests," added Radford.

And family members can go through a process with the DMV to accomplish the same. 

"If they feel like their mother or whoever it is to them shouldn't be driving anymore they can actually notify the DMV and they will be required to re-take their test," said Radford. 

Regardless, King says the decision is not easy.

"It's a difficult situation to take someones driving away... they may say I only drive two miles away," added King. "If they run into somebody on a bike or the side of a car somebody's affected."
