text: You will need your phone while driving if something serious happened or is happening and you need emergency services quick. Without your phone, you would be stuck out on the road during the day or even night with no one to help. Most people definitely don't like to stop for people even when they see they're in trouble. According to "NHTSA's Office of Emergency Medical Services" , "emergency telephone calls presented to the switchboard in May 2017 was 845,674, an average of 27.3 thousand per day.". This shows that many people use their phone to call EMS when any type of situation or car crash happens.
