In New Jersey, driving without proof of a license can lead to significant fines and legal consequences. If a driver is stopped and cannot provide a valid driver's license, they may face fines up to $500, court appearances, and potential surcharges. However, if the driver has a valid license but simply did not have it with them, presenting it later might reduce the penalties. Repeat offenses or driving with a suspended or revoked license can result in more severe consequences, including higher fines, increased surcharges, and potential imprisonment. Always carrying a valid driver's license helps avoid these issues and ensures compliance with state laws.
