New Jersey Officials Warn 4/20 Drivers: Drug-Impaired Crashes Linked to 26% of Serious Cases

SOMERVILLE, N.J. — New Jersey law enforcement is ramping up enforcement ahead of April 20, warning that drug-impaired driving—linked to 26% of serious or fatal crashes in a federal study—puts lives at risk across Somerset and Hunterdon counties.

The Somerset County Prosecutor’s Office, citing the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA), said drivers under the influence of marijuana or other drugs will face increased patrols and enforcement efforts on April 20.

Enforcement Push Targets Impaired Driving

Officials say the message is straightforward: impairment is illegal regardless of whether the substance is legal.

“If You Feel Different, You Drive Different,” the NHTSA campaign states, emphasizing that marijuana use can significantly affect reaction time, judgment, and coordination.

Somerset County Prosecutor John McDonald warned against a persistent misconception about drug use behind the wheel.

“Driving while impaired by any substance, legal or illegal, puts you and others in harm’s way,” McDonald said. “It is a common and dangerous misconception that people drive better when they are high.”

Research Highlights Risk on the Road

Federal data underscores the concern. According to NHTSA, between 2019 and 2021, 26% of drivers seriously injured or killed in crashes tested positive for marijuana.

Safety officials say the drug can slow reaction times, impair cognitive performance, and make it harder to maintain lane position—factors that significantly increase crash risk.

Key Points
• New Jersey law enforcement increasing patrols for 4/20 impaired driving
• NHTSA data shows 26% of serious or fatal crash victims tested positive for marijuana
• Officials warn marijuana impairs reaction time, judgment, and driving ability

Public Urged to Plan Ahead

Authorities are encouraging residents to take preventive steps, including designating a sober driver or using rideshare services if they plan to consume marijuana or alcohol.

They also urge people to intervene if they see someone preparing to drive while impaired.

“If you see a friend about to drive while high, take their keys and help them arrange a sober ride home,” officials said.

Drivers who encounter suspected impaired motorists are encouraged to contact local law enforcement.

What Comes Next

Law enforcement agencies across Somerset and Hunterdon counties will conduct stepped-up patrols and enforcement operations throughout April 20, focusing on identifying and stopping impaired drivers.

Officials say the initiative is part of ongoing efforts to reduce preventable crashes and keep roadways safe during high-risk periods.
