When may you use a mobile phone while driving in Puerto Rico?

In Puerto Rico, the law states that the use of mobile phones while driving is only permitted when using a hands-free device. This regulation is in place to promote safer driving and reduce distractions that could lead to accidents. Using a hands-free device allows drivers to maintain their focus on the road while still being able to communicate, thereby minimizing the risk associated with holding a phone in one hand while operating a vehicle.

The other options are not aligned with this law. Using a hand-held device is prohibited as it can significantly divert a driver's attention from the road. Allowing phone usage at any time would be counterproductive to road safety. Prohibiting all phone use while driving emphasizes the importance of staying focused on the task of driving without the distraction of a phone at all.
