Driver hits cows while checking email

Text messaging involves all of the above, though experts say it is also dangerous when drivers take their minds off the task of driving, as research shows human brains do not perform two tasks simultaneously, according to the National Safety Council.

Studies released by that group describe the brain as handling tasks sequentially and switching between one task and another.

The brain juggles tasks rapidly, leading people to believe they are performing two tasks at once.

When the brain processes information, it screens out information to deal with sensory overload.

When a driver’s brain is overloaded by talking on the phone while driving, the individual may not, for example, see a red light.

Experts say it is nearly impossible for people to realize that they are taking on too many tasks for their mental capacities.
