It's about time they start enforcing this. If you drive with a cell phone up to your ear and you don't think you're dangerous then you're crazy. Get these jerks off the road!

This is a ridiculous law. Eating while driving is more dangerous that using a phone while driving, yet eating while driving is not outlawed. I've already witnessed one near accident caused by someone getting a phone call and fumbling to get their hands free device out. This law does nothing to make the roads safer.

Note, the above does not apply to texting while driving which is significantly more dangerous that talking on the phone without a hands-free.

It's absolutely time to enforce this law. A couple of years ago I was nearly crushed between a woman (upper-middle-aged) entering Central Expressway with a cell phone plastered to her ear, and a laundry truck in Lane 1. She didn't even look or try to yield, and was still talking after the accident when she pulled over to the side of the road.

Just because there are other activities that interfere with safe driving (e.g., eating), that is no reason not to enforce hands-free driving laws.

Phil, you are zero for two on this

1) in recent data collected by the California Highway Patrol, it states that drivers using cellphones caused more fatalities than all the drivers distracted by eating, children, pets or personal hygiene.

2) texting while driving is illegal in Calif (from Jan 1 2009)

Although those might be the facts, common sense will tell you that its not the holding of the cell phone but the lack of attention while talking on the phone. Thats the problem and it will not change.
There are laws on the books for unattentive drivers and they are not enforsed or are ignored. Making new rules will not solve problems.
Generating revenue is all they do so lets not kidd our selves.
Personally I would preffer to hold the phone to my ear than fumbling with a blue tooth that only works for a few months and than takes a sh$t. Now I use the iphone earphones that makes people think that i am listening to my ipod, or I just pull over.
Either way, an ear piece is not the answer. Its the fact that it takes 15 min and 20 dollars to get a license that's killing people

I'm looking forward to the day when the deleterious health effects of cell phones become apparent. Their effect on the blood-brain barrier is very interesting. It's going to be fun.

Old Ben, Do you have any sources to cite on this? (ie. blood-brain barrier disruption...)

Just do a websearch on cell phones and "blood brain barrier."

Another related law that I'd like to see enforced more often is section 27400 of the vehicle code which makes it illegal to drive or ride a bicycle with headphones or earplugs in both ears.

I know cops do sometimes stop bicyclists for listening to music in both ears while riding, but it may be harder to spot for drivers. To me, it could be just as distracting as a phone call since the ambient noise around the driver/cyclist is mostly blocked.
