Introduction to Flying Over People and Moving Vehicles Under Part 107

Operating drones commercially in the United States demands strict adherence to Federal Aviation Administration (FAA) regulations. Part 107 governs commercial drone operations, setting forth rules for flight altitude, visibility, and operational limitations. Among the most critical and evolving aspects are the restrictions on flying over people and moving vehicles. These regulations are designed to minimize risks to persons and property on the ground. Understanding the current requirements, categories of operations, and waiver processes is essential for any Part 107 pilot aiming to conduct safe, legal flights in populated areas.

Since the original Part 107 went into effect in 2016, the FAA has updated its rules to better accommodate the growing commercial drone industry. In 2021, the agency introduced a performance-based framework that allows certain drones to operate over people and moving vehicles without a waiver, provided they meet specific design and operational criteria. This article expands on the original content, providing a detailed breakdown of these categories, the waiver process, and best practices for safe compliance.

Understanding Part 107 Regulations for Overflight Operations

Part 107, codified in 14 CFR Part 107, establishes the baseline for commercial small unmanned aircraft systems (sUAS) operations. The regulation originally prohibited flying over people who are not directly participating in the operation, as well as over moving vehicles, unless the pilot obtained a waiver. However, the 2021 rule (effective April 21, 2021) introduced four categories of operations over people, each with specific requirements based on the drone’s risk profile. This change allows many operators to overfly people and moving vehicles without needing a waiver, provided the drone meets the category’s standards.

The key shift was from a blanket prohibition to a performance-based approach. Instead of requiring waivers for nearly all overflights, the FAA now allows operations over people under Categories 1, 2, 3, and 4. The category determines the level of injury the drone could cause in the event of a failure, and the operational limits allowed (e.g., over crowds, over moving vehicles). For thorough understanding, pilots should review the official Part 107 text on eCFR.

The Four Categories of Operations Over People

The FAA defines four categories based on drone weight, design, and safety features. It’s critical to determine which category your drone qualifies for before planning any overflight.

Category 1 Operations

Category 1 operations allow for flights over people (including crowds) and over moving vehicles without any waiver requirement. However, the drone must weigh less than 0.55 pounds (250 grams) including payload and have no exposed rotating parts that could lacerate. No FAA-accepted means of compliance or declaration is needed; the operator simply weighs the drone and ensures compliance. Examples include small camera drones like the DJI Mini series (under 250g) without modifications.

Category 2 Operations

Category 2 applies to drones that do not meet the weight limit of Category 1 but have been designed to prevent serious injury to people in the event of a failure. The drone must have an FAA-accepted means of compliance, meaning the manufacturer must submit evidence that the drone’s design, safety features (such as propeller guards, parachutes, or redundant systems) keep the kinetic energy transferred to a human head below the injury threshold. The operator must have a manufacturer’s declaration of compliance. Category 2 allows operations over people and moving vehicles, but the FAA may impose additional operational limitations based on the drone’s performance in the event of loss of control.

Category 3 Operations

Category 3 is for drones that may cause higher injury potential but still feature risk mitigation measures. These drones cannot be flown over crowds (open-air assemblies of people) but can be flown over individual people and moving vehicles if the operation is conducted within a defined area where persons are on notice (e.g., a closed set or private property with informed participants). The drone must have an FAA-accepted means of compliance and a manufacturer’s declaration. Additionally, the operation must not involve sustained flight over people; incidental overflight is allowed.

Category 4 Operations

Category 4 requires the drone to be type-certified under FAA aircraft airworthiness standards (typically for manned aircraft) or meet equivalent safety levels. This category is for larger or more complex drones and requires a higher level of engineering review. Operations over people and moving vehicles are permitted, but the drone must have a standard airworthiness certificate or special airworthiness certificate. Category 4 is rarely used by small commercial drones; it is more relevant for eVTOL or heavy-lift UAS.

Flying Over Moving Vehicles Under Part 107

Flying directly over moving vehicles was historically prohibited without a waiver. The 2021 rule changed this by allowing overflight of moving vehicles if the operation meets the conditions for Category 1, 2, 3, or 4, and additional safety requirements are satisfied. Specifically, the drone must not create undue hazard to persons or property. For moving vehicles, the operator must ensure the drone does not cause a driver to swerve or become distracted. Key considerations include:

  • Direct Confirmation of Safe Design: The drone must be certified under one of the four categories. Category 1 drones under 250g are easiest, while larger drones need a waiver or acceptance.
  • No Sustained Flight Over Vehicles: The regulation allows temporary overflight, such as capturing footage of a moving car on a closed course, but not prolonged hovering above highways or traffic.
  • Operational Risk Assessment: Pilots must evaluate whether the overflight could cause a crash that leads to a vehicle crash. Even if the drone is compliant, situational awareness is critical.

The FAA’s Operations Over People page provides official guidance and links to the rule changes.

When Do You Still Need a Waiver?

Despite the new categories, some situations still require a waiver under Part 107. For example:

  • Flying over crowds (open-air assemblies) with a Category 3 or Category 4 drone that doesn’t meet the “no sustained flight” condition.
  • Operating a drone that does not have an FAA-accepted means of compliance (i.e., older models not recertified) over people or moving vehicles.
  • Flying over moving vehicles with a drone that does not meet any of the four categories.

To apply for a waiver, operators must submit an application through the FAA DroneZone portal, detailing the proposed operation, risk mitigations, and why it can be conducted safely. The approval process can take weeks or months. Pilots can search for existing waivers on the FAA website to see precedents.

How to Ensure Compliance Without a Waiver

To avoid the waiver process, ensure your entire fleet is composed of Category 1 or Category 2 drones (or Category 3 with restricted operations). For many commercial operators, this means using drones like the DJI Mini 3 Pro (under 250g) for flights over people, or larger platforms with manufacturer-provided declarations of compliance (e.g., DJI Mavic 3 Enterprise series may have Category 2 acceptance). Always verify the manufacturer’s documentation and keep a copy on hand. The FAA also maintains a list of accepted means of compliance.

Safety Best Practices for Overflight Operations

Even when regulatory compliance is satisfied, safety must never be compromised. Here are expanded best practices beyond the original list:

Pre-Flight Planning

  • Site Survey: Survey the area for any non-participating people, children, pets, or unexpected vehicle movements. Use a geospatial analysis tool to identify high-risk zones.
  • Risk Matrix: Create a risk assessment matrix considering factors such as flight altitude, wind speed, battery state, drone loss of signal, and proximity to obstacles.
  • Notification and Crowd Control: If flying Category 3, ensure all people in the area are informed and have consented to being overflown. Use barriers or signage to keep non-participants outside the operation zone.
  • Contingency Plan: Plan for failure scenarios—what happens if the drone loses GPS, has a motor failure, or its parachute deploys. Have an emergency landing site clear of people.

In-Flight Safety Measures

  • Maintain Visual Line of Sight (VLOS): Always maintain unaided visual contact with the drone, especially when flying near vehicles. Use a visual observer if needed.
  • Avoid Distractions: Do not fly in a manner that distracts drivers or pedestrians. For instance, avoid low-altitude flights over busy intersections.
  • Monitor Weather: Avoid flying in adverse weather—rain, high winds, or low visibility degrade drone performance and can cause sudden loss of control.
  • Use Safety Equipment: Equip drones with propeller guards (if allowed by manufacturer) or parachute systems like those from Indemnis or ParaZero to mitigate injury risk. However, ensure these additions do not affect the drone’s weight or category certification.

Post-Flight Review

  • Debrief each flight that involved overflight of people or vehicles. Log any near-misses or deviations from the plan. Use this data to improve future risk assessments.
  • Update your operations manual with lessons learned.

Flying over people and moving vehicles inherently increases liability exposure. Even fully compliant operations can result in damage or injury. Commercial drone operators should carry liability insurance that covers personal injury and property damage. Check with your provider to ensure your policy specifically includes “operations over people” if you routinely perform such flights. Some insurers require proof of FAA acceptance or waivers. Additionally, be aware of local and state laws that may impose stricter regulations—for example, some states prohibit drone flights over private property without consent.

Common Misconceptions About Overflight Rules

Pilots often misunderstand the 2021 rule. Here are clarifications:

  • “A remote ID will allow me to fly over anyone.” Remote ID is an identification requirement, not an operational authorization. It does not grant permission to overfly people.
  • “If I’m flying a sub-250g drone, I can fly over crowds anywhere.” Category 1 allows overflight of crowds, but the drone must have no exposed rotating parts. Many sub-250g drones have exposed propellers; you must add guards to qualify, but that may increase weight above 250g. Test thoroughly.
  • “A waiver is always required for flying over vehicles.” Not anymore—Category 1 and 2 drones can fly over moving vehicles without a waiver, provided the operation does not create a hazard. However, sustained flight over highways is still discouraged.
  • “If my drone is over 250g, I can never fly over people.” False—Category 2 and 3 allow it with proper certification and operational limits.

Conclusion: Integrating Overflight Safely Into Your Operations

The FAA’s transition to performance-based standards has significantly expanded opportunities for commercial drone pilots to safely fly over people and moving vehicles. By understanding the four categories, verifying your drone’s compliance, and following robust safety practices, you can avoid the lengthy waiver process for many routine flights. However, always treat overflight operations with increased caution—human safety is non-negotiable. Stay updated with FAA circulars and consider subscribing to industry updates. For official guidance, refer to the FAA Advisory Circular 107-2 for small unmanned aircraft systems.

Remember that regulations and manufacturer compliance statuses evolve. Regularly check your drone manufacturer’s documentation for updates regarding means of compliance. By integrating these guidelines into your standard operating procedures, you can conduct productive, safe, and legal operations over people and moving vehicles.
