We have all heard that texting and driving is a dangerous combination.  We have heard about lab tests but now Texas A&M University's Transportation Institute put the test on the road and showed just how dangerous it can be.  They took Forty-two drivers between the ages of 16- to 54-and put them behind the wheel in a closed track 11 miles long.   The tests showed the average, normal reaction times were about a second or two put a cell phone in the driver's hand and the reaction times jump to three or four seconds.  The study also showed the driver was 11 times more likely to miss a flashing warning light and had more difficulty driving straight while texting.
