New Jersey laws dealing with driving while intoxicated (DWI) are consistent throughout the state, meaning that prosecutors in each county in New Jersey must meet the same burden of proof to obtain a conviction. A review of municipalities around the state by NJ.com, however, has found that some local police departments are much more assertive in enforcing these laws. New Jersey law allows municipalities to regulate the sale of alcoholic beverages, including by prohibiting their sale within city limits. These “dry towns,” according to the NJ.com report, have some of the highest DWI arrest rates in the state. Differences in arrest rates can have many possible causes, including prioritization by local law enforcement.
A person commits the offense of DWI if they operate a motor vehicle while impaired by alcohol or drugs, or while they have a blood alcohol concentration (BAC) of 0.08 percent or higher. Police and prosecutors often prefer to prove impairment with BAC evidence, since a BAC above the “legal limit” of 0.08 percent creates a presumption of intoxication. They can also meet their burden of proof with evidence of how a driver behaved, appeared, or smelled at the time police pulled them over. During patrols, police may look for vehicles that are moving erratically, which could indicate impairment by a driver. Police are also allowed to operate roadside checkpoints for the purpose of checking motorists for common signs of intoxication. Each police department has wide leeway in setting enforcement priorities.
Businesses that serve or sell alcohol must have a license to do so. New Jersey law gives municipalities the authority to determine how many licenses, if any, to issue. A municipality might ban the sale of alcohol altogether, or it might prohibit retail sales while allowing restaurants to serve alcohol. New Jersey has 32 dry towns that prohibit alcohol sales to some extent. Most of these are located in the southern part of the state. Camden County is home to four dry towns: Audubon Park, Collingswood, Haddon Heights, and Haddonfield.
