In this article, we’ll explore what the law says about rolling your window down for police in New Jersey and discuss some tips to help you know what to do if a police officer approaches your vehicle.

New Jersey State Laws

New Jersey statutes, such as N.J.S.A. 39:3-29, require drivers to present their driver’s license, registration, and insurance information when stopped by law enforcement. However, these laws don’t specify the extent to which you must roll down your window.

The Fourth Amendment of the United States Constitution protects citizens from unreasonable searches and seizures. This extends to your vehicle, which is considered personal property.

In New Jersey, you are generally expected to roll down your window enough to facilitate clear communication with the officer and to hand over the required documents. This usually means rolling it down at least halfway.
