Their use while driving is prohibited. A hand on a phone is a hand off the wheel, and eyes on a screen are eyes off the road. New Jersey Driver Manual, p.85: “State law prohibits the use of handheld electronic devices (such as cellular telephone) while driving a motor vehicle on any public road or highway.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
