One of the most frequently misunderstood aspects of the 2021 Part 107 operations-over-people update is how it changed the rules for flying over moving vehicles. The short version: it relaxed the restriction, but only for aircraft that meet specific safety standards most consumer drones cannot claim to meet.
The Original Rule
Under the original Part 107 (effective 2016), drones could not fly over moving vehicles. Period. This affected real estate photography over active roads, news coverage, infrastructure inspection near highways, and many other common commercial applications.
The restriction existed because a drone falling on a moving vehicle could cause a serious accident -- the vehicle could swerve, occupants could be injured, and secondary collisions could follow.
What Changed in 2021
The FAA's final rule on operations over people, effective April 21, 2021, allowed operations over moving vehicles under Category 2 (and higher) compliance.
Category 2 requirements for operations over moving vehicles:
- The aircraft must have received FAA-accepted means of compliance documentation demonstrating it will not cause injury exceeding 11 foot-pounds of kinetic energy upon impact with a human head
- The aircraft must be labeled "Cat 2" or traceable to Category 2 compliance
- The operation cannot be over open-air assemblies
Critically, Category 1 (sub-250g aircraft) does NOT permit operations over moving vehicles -- only over stationary people. The distinction matters: a 250g drone hitting a car windshield at speed could still cause a serious accident.
What This Means for Consumer Drones
Most popular consumer drones are not Category 2 certified. DJI has pursued FAA acceptance for some aircraft in some categories, but as of 2026 the consumer market has not widely adopted Category 2 certification.
This means that for most pilots flying Mavic 3, Air 3, Mini 4 Pro, or similar aircraft, flying over active public roads remains off-limits.
The Mini 4 Pro (249g) qualifies for Category 1 for operations over stationary people -- but not for moving vehicles under any current category.
The Controlled Environment Exception
Category 3 permits operations over moving vehicles if those vehicles are inside a controlled or restricted-access area where people are warned that a drone may fly overhead. This applies to:
- Private industrial facilities
- Controlled construction sites with access management
- Film sets and production environments where the public has been excluded
The vehicles must be inside the restricted-access perimeter. This does not extend to public roads adjacent to a controlled site.
Practical Approaches
For pilots who need aerial footage over or near roads:
Wait for a traffic gap. Many road shots are captured during natural traffic gaps rather than requiring sustained flight over moving vehicles.
Use longer focal lengths from a safe distance. Staying off to the side of a road while capturing road-adjacent footage avoids the flying-over restriction.
Coordinate access closures for commercial productions. Film and commercial production work often includes road closures or controlled access as part of the production logistics.
Use Sub-250g aircraft for Category 1 compliance. For operations over people (not vehicles), the Mini 4 Pro and similar sub-250g drones allow significantly more flexibility.
The Bottom Line
Operations over moving vehicles require Category 2 aircraft with FAA-accepted means of compliance -- documentation that most consumer pilots do not have and most consumer drones do not carry. If your aircraft is not Category 2 certified, avoid sustained flight directly over moving vehicles on public roads. Flying parallel to or near roads (without directly overflying moving vehicles) is a different operational judgment.
