US-FAA14 CFR 107.27

Alcohol or drugs

Read the official rule

This regulation requires anyone operating a drone under Part 107—whether manipulating the controls, acting as remote pilot in command, or serving as visual observer—to follow the same alcohol and drug rules that apply to manned aircraft pilots.

Specifically, you must comply with §91.17 and §91.19, which prohibit:

  • Operating within 8 hours of consuming alcohol
  • Operating while under the influence of alcohol
  • Operating with a blood alcohol content of 0.04% or higher
  • Operating while using any drug that affects your abilities

This means drone operations have the same strict substance restrictions as flying airplanes. You cannot legally fly a drone commercially if you've been drinking recently or are impaired by any substance, even if it's legal or prescribed. The FAA can also require testing if there's reasonable basis to believe you violated these rules.
