Drone rules explained: height limits, no-fly zones, registration and ID

TUREFF• •0

Drone rules can look different in every country, but most are built on the same few principles. Learn those and you will understand the local details much faster. This guide covers the common ground and uses the UK and US as examples. It is a starting point, not legal advice: always check your own regulator's current rules before you fly.

The principles most countries share

Keep it in sight. You should be able to see the drone with your own eyes, not only through the screen. FPV flying usually needs a spotter or a special arrangement.
Stay low. Many countries cap leisure flying at around 120 m (400 ft) above the ground, to keep drones below most crewed aircraft.
Stay away from airports and airfields. Restricted zones around them are common and strictly enforced.
Respect restricted airspace: military sites, prisons, some government buildings and temporary restrictions for events or emergencies.
Keep away from people. Flying over crowds is widely banned, and many rules set distances from uninvolved people.
Register or take a test where required, and label the drone with your ID.

The UK

The Civil Aviation Authority (CAA) sets the rules and publishes the Drone and Model Aircraft Code. From 1 January 2026:

Flyer ID: needed for anyone flying a drone or model aircraft of 100 g or more. You get it by passing a free online theory test.
Operator ID: needed for drones of 250 g or more, and for drones of 100 g or more with a camera. The person responsible for the drone registers, pays an annual fee and labels the drone with the ID. You must be 18 or over to get an Operator ID.
Under 100 g: no IDs required, though the CAA recommends taking the test anyway.
Height: stay below 120 m (400 ft) from the closest point of the earth's surface.

Newer drones sold in the UK carry class marks that affect where and how close to people you may fly. The CAA website explains the categories and has the current fee.

The US

The Federal Aviation Administration (FAA) separates recreational flying from commercial work.

Recreational flyers must pass TRUST (The Recreational UAS Safety Test), which is free and online through FAA-approved test administrators, and carry proof of passing.
Registration is required for a drone flown only for recreation if it weighs more than 250 g (0.55 lb). Registration is done online through the FAA's DroneZone, and your number goes on the drone.
Remote ID: drones that need registering must broadcast Remote ID, unless flown at an FAA-recognised identification area.
Height: recreational flyers stay at or below 400 ft above ground level in uncontrolled airspace. Flying in controlled airspace near airports needs authorisation.
Commercial work (being paid, or flying for a business) falls under a separate set of rules and a remote pilot certificate.

No-fly zones

Most regulators publish official maps or apps showing restricted airspace. Check before every flight, because temporary restrictions appear for events, emergencies and VIP visits. Many drones have built-in geofencing, but it is not a legal guarantee; responsibility stays with you.

Other laws still apply

Aviation rules are not the whole picture.

Privacy and data protection law can apply when you film identifiable people.
Land access: parks, nature reserves, national parks and private land often have their own rules about taking off and landing.
Local bylaws can ban flying in specific places.
Insurance is compulsory for some kinds of flying in some countries and sensible everywhere.

Travelling with a drone

Rules abroad can be very different, and some countries restrict or ban importing drones. Check the destination's aviation authority, as well as your airline's rules on carrying lithium batteries, before you pack. Thresholds, fees and categories change often, so check the CAA, FAA or your own national regulator before flying. Have a question about your country's rules, or a tip from flying abroad?
