This is the fourth year Senator Nancy Detert has sponsored the bill and the first it's been heard in the House. The Senate passed it unanimously two weeks ago.
But when the bill came up on the House floor Tuesday, Representative Jose Oliva offered an amendment banning prosecutors from using a driver's cell phone records, except in cases of death or injury.
"This law is important to me. And as many times as it comes up while I'm here, I will support it. But any law that seeks to give up our civil liberties, or asks us to, I will look to amend so it doesn't do that."
Detert watched grimly from the back of the chamber as Representative Kevin Rader said she opposed the amendment.
Representative Gayle Harrell said the amendment's content was no problem, but its timing was.
"And I have a great deal of fear that this might just sink the bill, members. It is not worth the risk. It is one of the most important bills that we are going to pass this year."
The amendment passed 73 to 46.
Detert says the House has had the bill for weeks and should have amended it already.
Now the bill rolls over to third reading in the House.
