Question 4 of 5: Drivers who text spend about 10% of their driving time outside their own driving lane.
Mnenie [13.5K]

Drivers who text spend about 10% of their driving time outside their own driving lane. True

<h3>Briefing:</h3>

It is accurate to say that 10% of the time texting while driving is spent in the incorrect lane. Driving while texting is extremely risky because it diverts the driver's attention from the road, making it impossible for him to see. According to research, 60% of people use cell phones while driving, making texting while driving a serious issue.

<u>Using a phone while driving raises the likelihood of an accident.</u>

Texting or using a phone in any other way has regularly been connected by researchers to higher risk. Talking on a telephone while driving has been linked to an increased crash risk in certain studies, but not all.

One of the major causes of many traffic collisions is using a cell phone while driving. Due to how distracting cell phone use is to a person's attention and mental focus, it is illegal to use a cell phone while driving in many nations.
