Although its origins are uncertain, April 20th (more commonly known as
420) has become synonymous with marijuana use and, in some circles, the
date is a marijuana “holiday.” On Tuesday, April 20, 2021, there will likely be an increase in marijuana use. NHTSA is teaming up with State and local traffic safety advocates to spread the message that drug-impaired driving of any kind is dangerous and illegal.
NHTSA wants to remind all drivers: If You Feel Different, You Drive Different.
