Under what circumstances may you use your cellphone while driving?

Using a cellphone while driving is governed by strict regulations intended to enhance safety on the road. The correct answer emphasizes the importance of hands-free devices. When a driver is using a hands-free device, they are able to communicate without taking their hands off the steering wheel, allowing them to maintain better control of the vehicle while focusing on the road. This feature is designed to minimize distractions, helping to prevent accidents caused by divided attention.

While there are contexts in which using a cellphone is more restricted, including when parked or at traffic lights—where the driver is stationary but may still have their attention diverted—the use of hands-free technology allows drivers to stay connected while minimizing potential dangers. It provides a balance between communication needs and the necessity of maintaining a safe driving environment.
