As 4/20 approaches, federal officials are ramping up a nationwide campaign aimed at one message: don’t get behind the wheel if you’re high.
Led by the National Highway Traffic Safety Administration, the effort is part of a broader push to reduce drug-impaired driving during peak cannabis holidays. The campaign leans on a familiar slogan—“If You Feel Different, You Drive Different”—while tailoring its messaging specifically to April 20, a day widely associated with increased marijuana use.
Rather than focusing on prohibition-style warnings, the initiative uses culturally aware visuals and messaging to reach cannabis consumers directly. Ads encourage people to plan ahead—designate a sober driver, use rideshare services, or avoid driving altogether if they’ve consumed THC.
Officials emphasize that regardless of legalization status, driving under the influence of marijuana remains illegal across the U.S. and poses real safety risks. Research shows cannabis can slow reaction time, impair coordination, and affect decision-making behind the wheel.
The campaign also includes ready-to-use materials for local agencies, from social media graphics to highway message board slogans like “Drive Sober on 420” and “Don’t Drive High.”
Still, the issue remains complex. Unlike alcohol, there’s no clear-cut THC threshold that reliably indicates impairment, making enforcement and public education an ongoing challenge.
With cannabis use becoming more normalized, the federal message is shifting too: it’s less about telling people not to use—and more about making sure they don’t mix it with driving.
