Unless the apologists for the new law want to claim that the police can't arrest someone for DWI who's passed out at a stoplight with the car running, then clearly the law applies to people stopped at a stoplight, and it clearly applies to reading texts. This whole issue is just the latest example of Idaho legislators who want to control the lives of those without political power -- in this case, teenagers. They claim they want to save lives, but what they're really interested in is passing a law that criminalizes behavior they lack the technical wherewithal in which to engage that's mostly being practiced by people they don't understand.
There are approximately 250 people a year who die in Idaho traffic crashes every year, and in essentially every case the accidents involve cars going over 20 MPH. However, I note that there's no bill currently introduced to lower the speed limit to 15 MPH (with exceptions for emergency vehicles, of course). I guess Idaho legislators are happy sending these 250 people to fiery deaths each year so they can race along at 50 MPH to get to the coffee shop for their mocha latte. [Rant inspired by Berkeley Breathed] Who knows, maybe next the Idaho Senate will decide that people are at risk of running off the road if they're outraged by the sight of people of different races walking down the street engaged in PDA, so they'll outlaw miscegenation. All in the interest of public safety, of course...
Hopefully the Idaho House will see through this attempt at election year political grandstanding, and keep this flawed bill from passing (or at least amend it so that it's clear that it doesn't apply to the simple act of reading texts, especially when stopped).
Update 0923 11 Mar: It was brought to my attention that the bill that actually passed the Senate was amended to specify that it only applies to a "moving" motor vehicle. (I linked to the bill as originally submitted above.) My point remains that this is an attempt to pass a politically popular new restriction on citizens by the state during an election year where there's a lot of anger at incumbents aimed squarely at a group without a lot of political power.
Update 1438 12 Mar: Here's another potentially dangerous activity the Idaho Legislature should outlaw while they're at it -- driving while shaving your "bikini area".
