According to a study in 2005, it was suggested that it would not necessarily improve safety if drivers switched to hands-free phones. Despite this claim, it is known that texting has become more popular in recent years instead of talking on the phone, especially amongst younger drivers and phone users.
Other studies have shown that using hand-held cell phones can cause a hazardous distraction, refuting the previous study that hands-free phones are not as dangerous as hand-held phones. Talking on a phone while driving is the same as driving drunk, with another study showing that drivers who talked on hands-free cell phones were 18% slower in braking and 17% longer to regain the speed prior to braking.
In addition, the studies focusing on hand-held cellphone bans have influenced state laws and regulations regarding distracted driving. The Highway Loss Data Institute studies found that cellphone bans do not reduce crashes – however, there are discrepancies on how the studies have been conducted, which could have been a key factor in the adoption of laws by each state.
