What are the rules about using a cell phone while driving?

The correct response highlights the law in New Jersey regarding the use of cell phones while driving. It's illegal to use a handheld device unless it's hands-free, which emphasizes the importance of keeping both hands on the wheel and maintaining full attention on the road. This regulation is in place to enhance safety and reduce distractions, as using a handheld device can significantly impair a driver's ability to react to traffic conditions and emergencies.

The other options imply various allowances that do not align with the legal standards in the state. For instance, suggesting that using any cell phone is acceptable while stopped does not account for broader safety concerns, as even when stopped, a driver might still be distracted by the device. The idea that using a cell phone while driving is permitted at all times directly contradicts driving safety regulations, while asserting that only texting is prohibited minimizes the dangers associated with all forms of phone use while operating a vehicle. Hence, the first option accurately reflects the established laws and their purpose.
