In the UK, the Civil Aviation Authority (CAA) regulates drone flights.
While the CAA doesn’t explicitly state that you can’t fly drones over a motorway, they do advise avoiding congested areas, including roads, and staying at least 50 meters away from vehicles, people, and property that doesn’t belong to you or that you don’t have control over. Before flying a drone over a motorway in the UK, it is important to notify the relevant authorities and obtain any necessary permits or approvals
In this article, we will explore the legalities and safety considerations of flying a drone over a motorway in the UK.
Laws Around Flying A Drone Over A Motorway in The UK
As a drone operator in the UK, it’s important to understand the regulations and guidelines put in place by the Civil Aviation Authority (CAA) to ensure the safe and responsible operation of your aircraft. One question that many drone pilots have is whether they are allowed to fly their drone over a motorway.
The CAA doesn’t explicitly prohibit flying over a motorway, but they do advise against flying in congested areas. In their Drone and Model Aircraft Code, the CAA states that drone operators should avoid flying over or near congested areas, and should remain at least 50 meters away from vehicles, people, and property that they don’t have control over. This rule is in place to protect the safety and interests of the public, as well as to prevent incidents that could cause harm or damage.
However, it’s important to note that the drone laws for flying in congested areas may vary depending on the class of your drone.

Drone Size And Flying Over UK Motorway
In the UK, drones are classified into four categories based on their weight and the level of risk they pose. The categories are C0, C1, C2, C3, and C4, with C0 being the smallest and C4 being the largest.
In the UK, drones are classified into four different categories based on their weight and the level of risk they pose:
Drone ClassWeight Range (grams)Can Fly Over Motorway? | ||
---|---|---|
C0 | < 250 | Yes, with caution and approval |
C1 | 250-500 | Yes, with caution and approval |
C2 | 1-4 kg | No, with caution and approval |
C3 | 4-25 kg | No, not recommended |
C4 | 4-25 kg | No, not recommended |
According to the regulations set by the Civil Aviation Authority (CAA), drones in the C0 and C1 categories, which weigh less than 500 grams, are allowed to fly over a motorway with caution. However, the CAA advises against flying in congested areas such as motorways, and recommends staying at least 50 meters away from vehicles, people, and property that you don’t have control over.
Drones in the C2 category, which weigh between 1 and 4 kilograms, are also allowed to fly over a motorway with caution and appropriate safety measures. However, the CAA advises against flying in congested areas such as motorways, and recommends staying at least 50 meters away from vehicles, people, and property that you don’t have control over.
Drones in the C3 and C4 categories, which weigh between 4 and 25 kilograms and over 25 kilograms, respectively, are not recommended to fly over a motorway. These larger drones pose a greater risk and are subject to stricter regulations. The CAA advises against flying in congested areas such as motorways, and recommends staying at least 150 meters away from industrial, residential, or commercial areas.
Tips For Flying Your Drone Over UK Motorway
Flying a drone over a motorway can be a thrilling and unique experience, but it’s important to follow the rules and regulations to ensure the safety of yourself, your drone, and others on the road.
Here are some best practices for flying a drone over a motorway in the UK.
Avoid rush hour traffic
One of the most important safety considerations when flying a drone over a motorway is to avoid peak traffic times. This will help prevent your drone from interfering with cars and causing any accidents or distractions. A good time to fly would be early in the morning or late at night when traffic is lighter.
Fly at a Safe Altitude
Another important safety measure is to maintain a safe altitude when flying your drone over a motorway. The CAA recommends flying at least 100 meters (328 feet) off the ground to avoid distracting drivers and to provide enough space for your drone to manoeuvre. This altitude also falls within the 400-foot legal limit for flying drones in the UK.
Plan your flight route
It’s important to plan your flight route carefully to minimise the amount of time you spend over the motorway. This will help you avoid any potential conflicts or hazards, and will ensure that you are not violating any laws or regulations. You can use a drone mapping app or software to plan your route and avoid any restricted areas or no-fly zones.
Keep a reasonable distance
Keep a reasonable distance when photographing a UK motorway. If you plan to film the motorway itself, make sure to keep a reasonable distance from the cars on the road. This will help prevent your drone from interfering with traffic, and it will also ensure that you capture clear, unobstructed footage.
Follow the CAA’s regulations
Finally, it’s important to always follow the regulations set by the Civil Aviation Authority (CAA) when flying a drone in the UK. Follow all laws and regulations. Finally, it’s important to follow all laws and regulations when flying your drone over a motorway. This includes staying at least 50 meters away from people, vehicles, and property that you don’t have control over, and avoiding flying in congested areas such as motorways. As well as obtaining the appropriate permission from the CAA, if necessary, and following the guidelines for flying in congested areas. By following these best practices and taking the appropriate safety measures, you can enjoy flying your drone over a motorway while staying safe and legal.

Reasons Why You Would Need to Fly a Drone Over a Motorway
There are several potential reasons why you might need to fly a drone over a motorway in the UK. Some possible reasons include:
- Filming or photography: Drone cameras are capable of capturing unique aerial perspectives that are difficult to achieve with other types of equipment. If you are a filmmaker or drone photographer, you may want to fly your drone over a motorway to capture footage or images that you can use in your work.
- Infrastructure inspection: Drones can be used to survey infrastructure such as bridges, tunnels, and roads from a safe and convenient vantage point. If you are a civil engineer or other professional involved in infrastructure maintenance, you may need to fly a drone over a motorway to assess its condition and identify any potential issues.
- Emergency response: Drones can be an effective tool for responding to emergencies such as accidents or natural disasters. If you are part of an emergency response team, you may need to fly a drone over a motorway to assess the situation and provide assistance as needed.
- Traffic monitoring: Drones can be used to monitor traffic patterns and flow on motorways, which can help authorities identify potential bottlenecks or other issues. If you are a traffic management professional, you may need to fly a drone over a motorway to collect data and provide insights that can help improve the efficiency and safety of the road network.
Overall, there are many potential reasons why you might need to fly a drone over a motorway in the UK, from capturing aerial footage to responding to emergencies and monitoring traffic.
Who Should You Notify Before Flying Over a Motorway
Before flying a drone over a motorway in the UK, it is important to notify the relevant authorities and obtain any necessary permits or approvals.
This may include:
- The Civil Aviation Authority (CAA),
- The local council
- The police
- Local Air Traffic Control
It is also recommended to notify any nearby residents and businesses of your plans, to avoid any potential conflicts or misunderstandings.
It would be nice to condense down the laws as they apply to drones under 250gms as often referrals seem to imply that flying drones in certain areas is not allowed, but read on, and they are. One has to scrutinise the laws to clearly see what applies in certain circumstances, and to which class of drone they apply to.
