ARLINGTON (CBSDFW.COM) – Texting while driving could cut into your holiday shopping budget in a big way beginning today in Arlington.

The city’s controversial ban on texting while driving is now in effect.

Many residents have argued about the city council’s approval of the ban.   Residents say that the law, which still allows talking on the phone, is unenforceable.

Tiara Ellis Richard with the police department says it is up to the officer to determine whether you’re in violation.

KRLD’s Matt Thomas Reports:

The city says you can show the officer your phone in an effort to prove your innocence.  Or, the city says, if you can prove in court that you were not texting, the ticket will be dropped.

The police department insists that the law is only designed to cut down on the number of wrecks caused by distracted driving.
