420 Warning: If You Feel Different, You Drive Different
Missoula, MT (KGVO-AM News) - On April 20, 2026, the U.S. Department of Transportation’s National Highway Traffic Safety Administration is reminding drivers that it’s illegal in every state and territory to drive under the influence of drugs.
On “420”, a number associated with marijuana, some might observe a day of increased marijuana use. But, no matter the day, the message is the same: If You Feel Different, You Drive Different.
“Driving while impaired by any substance — legal or illegal — puts you and others in harm’s way,” said Sergeant Swartz. “It’s a common and dangerous misconception that people drive better when they are high.”

According to Missoula Police Department Public Information Officer Whitney Bennett, driving high has serious and deadly consequences.
“A NHTSA study, from 2019-2021, showed that 26% of drivers seriously injured or killed in crashes tested positive for marijuana,” Bennett said. “If someone sees a friend who is about to drive high, they should take away the keys and help them get a sober ride home. And, if anyone spots an impaired driver on the road, contact local law enforcement.”
Drugs, including marijuana, affect driving abilities, which Bennett said puts everyone on the road at risk.
“It has been proven that marijuana can slow reaction times, impair cognitive performance, and make it more difficult for drivers to keep a steady position in their lane,” Bennett said. “These are all unsafe driving behaviors that can cause serious injuries or death in a crash.”

Bennett said a key to preventing impaired driving is to plan ahead.
“Designating a sober driver, that’s someone who won’t be drinking or using drugs, is one option,” Bennett said. “Other options include booking a rideshare or using a taxi. Join NHTSA in sharing the lifesaving message, If You Feel Different, You Drive Different.”
