konstantin123 [22]

Studies have suggested that texting or using a cell phone while driving is as dangerous as:- <u>"driving under the influence of </u><u>alcohol</u><u> or drugs."</u>

<u />

Drivers talking by cell phone drove significantly worse than drivers talking to passengers. The cell phone users have been much more likely to drift off their lane, kept a greater distance between their vehicle and the car in front, and were 4 times more likely to miss pulling off the highway at the rest area.

The usage of your cellular phone even as riding is not only risky but also illegal. In California, you cannot use a mobile cellphone or similar digital communication tool while holding it in your hand. You can only use it in a hands-loose manner, such as speakerphone or voice commands, but never while holding it.
