NAPLES, FL - Flashing your car's headlights is a way drivers can talk to other drivers. And it was once illegal to flash those light to warn others of lurking police.

"Really?"

But with a new law in effect today, it's not illegal anymore. And many drivers are happy about it.

"I think we should have the freedom to do that, if someone's setting up to trap you, you should be able to let other people know," said Richard Franciola.

Others say they're torn between helping other drivers:

"I don't want to give anybody the advantage, you know, if you're gonna go speeding, you pay the fine, pay the ticket," said Bill Soares.

And allowing the police officers to work.

"They're doing their job and you shouldn't be speeding in the first place. So you should be mindful of the speed limits and other drivers and motorcyclists," said Sandra Howells.

"I used to do it when I was younger, I would flash them, and I kept flashing them for miles. So I was guilty of it," said Soares.

Other changes to the law includes changes to speciality license plates and a free state identification card for homeless people.
