In New Jersey, you can be convicted of a DWI/DUI if you operate a motor vehicle (land or water) while under the influence of alcohol, narcotics, or other habit-forming drugs. The details of this law are explained in greater detail in state statute N.J.S.A. 39:4-50. Penalties associated with a DWI or DUI in New Jersey can include jail time, hefty fines, and driver's license suspension. In addition to the penalties listed above, you will also acquire up to 9 points on your license. A large number of points on your license may require high car insurance rates, or you may not be able to obtain a policy at all.
It is your right to refuse a BAC test in New Jersey. However, if you refuse the test and reasonable circumstances present that make the request feasible, you could be charged for refusing. The reason New Jersey residents can be charged for refusing to take a BAC test is because permission is granted for chemical tests, if circumstances are reasonable to require one, when a NJ driver's license is granted.
