Under what circumstances can a driver legally use a cell phone without a hands-free device?

Using a cell phone without a hands-free device is generally restricted to specific circumstances to ensure road safety. The correct answer pertains to situations deemed emergencies, which can include calls to emergency services, reporting hazardous conditions, or other urgent matters that require immediate attention. The law prioritizes the safety of the driver, passengers, and other road users, and allows for the use of a cell phone in these critical situations.

In contrast, using a phone while having a conversation with a passenger or waiting at a traffic light is not considered a valid exception under most traffic laws. This is because even brief distractions can lead to accidents. Furthermore, the speed at which a driver is traveling does not justify the use of a handheld cell phone, as the distraction associated with using a phone poses a risk regardless of speed.
