Alcohol and Pot Use by US Drivers Is Rising, Along With Deaths

  • AAA also found more drivers speeding, running red lights
  • Impact of marijuana on crash risk is difficult to determine

A growing number of US drivers are getting behind the wheel after using alcohol or marijuana, contributing to an increase in road deaths.

Dangerous driving behaviors — from impaired driving to running red lights to speeding — rose last year, reversing declines since 2018, according to a new survey from the American Automobile Association. Motor vehicle fatalities increased 10.5% to almost 43,000 in 2021, AAA said, citing federal estimates.
