What action is illegal for drivers to take on New Jersey roads when it comes to cell phone use?

Texting while driving is illegal in New Jersey due to the significant distraction it causes. Engaging in texting diverts a driver's attention from the road, increasing the risk of accidents. The law aims to reduce this risk by prohibiting any use of a handheld device for texting, as it involves composing messages that take one's focus away from driving.

While using a speakerphone feature and utilizing a cellphone at a stoplight may also be discouraged due to potential distractions, they are not specifically prohibited under New Jersey law. The emphasis is on preventing activities that compromise road safety, and texting while driving is considered particularly hazardous.
