Arnold Schwarzenegger says `` swift action '' will be taken on wife Maria Shriver 's driving `` violations . '' Web site TMZ posted a 17-second video Tuesday showing the California first lady apparently speaking into a cell phone while turning a corner in Brentwood in a black SUV . She puts the phone down part way through the video , but it 's not clear whether she did so because she had finished her conversation or because she noticed cameras following her . The site also photographed Shriver allegedly chatting while driving on Sunday and on June 12 . Shriver 's husband , California Gov . Arnold Schwarzenegger , last year supported and signed into law a ban on using handheld communication devices while driving . Enforcement of the ban began July 1 , 2008 ; it carries a $ 20 fine for a first violation ; $ 50 for each subsequent offense . A similar law banning texting while driving took effect January 1 this year . Watch Shriver driving while on her cell phone .

On Tuesday , Schwarzenegger sent a Twitter message to TMZ editor Harvey Levin : `` Thanks for bringing her violations to my attention . There 's going to be swift action . '' What that action might entail was not specified . Shriver on Wednesday issued an apology : . `` I 'm sorry , '' she said in a statement . `` I will be donating my favorite old cell phone to my Women 's Conference partner Verizon through their HopeLine program that helps domestic violence shelters . I invite anyone else who wants to recycle their old phone to join me . That 's my version of swift action with a higher purpose . '' The traffic office referred questions about Shriver to the governor 's office , which declined to comment . `` We do n't really think that hand-held bans have a whole lot of impact , '' said Jonathan Adkins , spokesman for the Governors Highway Safety Association in Washington . The association urges drivers not to use phones , including hands-free devices , while driving , but does not support laws banning them , he said . The attention to Shriver `` alludes to a bigger problem , and that 's the fact that everybody does it , '' Adkins said . `` Not only are public officials doing it , but we have to educate the highway safety community . ... Cops frequently are on their cell phones when they drive . `` The Shriver case really underscores the scope of the problem . We have a lot of educating to do . '' Shriver 's most recent alleged violations come on the heels of AAA Northern California 's `` Heads Up Driving Week , '' during which the auto club urged motorists to get in the habit of driving without distractions such as cell phones , fast food and tuning the stereo . `` We hope that by driving distraction-free for a week , people can pick up the habit for life , '' AAA spokesman Matt Skryja said in a news release . Seven states and the District of Columbia ban all handheld cell phone use by drivers . Several other states allow localities to set their own limits on cell phone use .
