Tennessee Permit Practice Test

Using a cellphone while driving is permitted in Tennessee under specific conditions. The correct choice reflects that individuals over 18 can use their cellphones, provided they are in hands-free mode. This is in line with state laws aimed at reducing distractions for drivers, ensuring that they remain focused on the road while still being able to communicate if necessary. The emphasis on hands-free mode is critical because it minimizes the risk of drivers taking their hands off the wheel or their eyes off the road, thereby enhancing overall traffic safety. Tennessee's regulations are designed to balance the need for communication with the imperative of safe driving practices. The other scenarios do not align with the current legal framework. For instance, using a cellphone for any purpose at all times, regardless of age, overlooks safety stipulations. Allowing cellphone use in emergencies only does not capture the nuances of the law that allows hands-free usage for adults. Lastly, permitting cellphone use when driving under 40 mph implies that speed alone could dictate the legality, which is not the case in Tennessee law.
