Operating a cell phone while driving in traffic is a risky proposition. With your attention split between the road and the call, the chances that you might get into an accident significantly increase.

Not only that, but many municipalities have introduced fines and penalties for using a cell phone on the road.

However, most of these laws allow for drivers to receive calls on a hands free system, which has been proven to be much safer than a hand held unit for automotive use.

A hands free system typically consists of an ear piece and a microphone that clip onto the driver, although some cars have the entire system integrated into the factory stereo. With the push of a button, you can answer the call and keep both hands on the road.

Even still, as with any road going distraction, it’s still not recommended to spend a lot of time on the phone while driving. How are you to know whether the call coming in is truly important or merely a friend wanting to chat? A Bluetooth hands free caller ID display can be integrated into your existing hands free system and take the guess work out of your ringtone.

The caller ID display is a small screen that can be placed in your line of site – typically on a dashboard vent, or even on the sun visor. When a call comes in, your phone connects to the display via Bluetooth, which is a wireless communications standard that allows portable devices to communicate with each other over short distances.

The number of the person calling you is shown directly before your eyes and you can choose whether to answer the call or whether to let your answering machine pick it up. Many units also come with additional features like call memory, so you don't have to jot down any numbers on the go.

The Bluetooth technology means there is absolutely no installation – just stick it on your dash, power it on, and it works perfectly with your phone.
