Memphis, TN- Dozens of new bills were signed into law in Nashville.  From scrap metal to tracking sex offenders, there are many changes you need to know about.

Sex offenders now need to give a DNA sample when registering, and homeless sex offenders must check in once a month.

The state is cracking down at scrap metal yards.  From now on if you are trying to sell copper or catalytic converters from cars, you're not going to get paid in cash.  Instead, scrap metal yards will cut you a check.  That is after you show a valid state ID and register your thumbprint with the scrap yard.  Plus, all scrap metal yard owners now have to be registered with the state Department of Commerce.

Remember all that chaos a few months ago when Hannah Montana came to town?  Concert tickets sold out in record time and were bought in bulk by scalpers.  Then the tickets were re-sold at astronomical prices.  Now, using the software that allows scalpers to do that is illegal.   

If you're going to go get a tattoo or piercing and are under 18, better make sure your mom or dad goes with you.  All minors must have consent.  A parent has to be present and prove they are the minor's mom or dad.

The next time it floods, you might want to think twice before driving through the water.  Ignoring flood warning signs or barricades is now considered reckless driving.

A new credit card restriction prevents banks from preying on college students.  The fine is going up for parking in a handicap space to $200.  All day care center employees must go through a background check.  Right now, the state lets you use deadly force when someone breaks into your home or tries to carjack you.  Business owners also have that right in the places they work.

In other areas of the Mid-South, Mississippi parents now have to buckle their children into booster seats until they are six years old.  In Arkansas, business owners can be fined a thousand dollars if they don't drug test employees who drive and register those results.
