New Jersey imposes criminal and administrative penalties for those convicted of a first-time DUI. Note that under New Jersey’s implied consent laws, offenders refusing to submit to a breathalyzer, first offense, face seven months of license revocation.
Sobriety checkpoints are legal in New Jersey (see 567 A.2d 277 (N.J. Super. 1989)). These checkpoints (also referred to as "mobile checkpoints" or "roadblocks") are police traffic stops that are not tied to any specific or individual suspicions.
