Carjacking is a form of robbery that involves stealing a motor vehicle by using or threatening force, and is elevated to first degree status, meaning that the punishment is more serious than other types of robbery. Conviction for carjacking carries a minimum five-year prison sentence in New Jersey, but can result in a much longer sentence—up to 30 years in prison. Substantial monetary fines—often in excess of $100,000—will also apply if you are convicted of carjacking.
