It is the question almost everyone asks before buying their first twist-and-go: do I actually need a licence to ride this thing? The honest answer depends on where you live and on the size of the machine. A 50cc moped and a 125cc scooter are treated very differently, and the rules in the United Kingdom look nothing like the patchwork across the United States. This guide covers both, in plain language, so you know what licence, training and tests stand between you and the road.
For context, I ride a small machine and I build Urban Rider, a navigation app for two-wheelers, so I read a lot of fine print on what these vehicles may do. Licensing is the first rule that matters; where your scooter can legally go is the second, which I cover in a separate guide on riding a moped on the motorway.
First, what counts as a moped?
The word "moped" has a precise legal meaning, and it is the dividing line for everything that follows: a small, low-powered two-wheeler with a capped engine and a capped top speed. Step over that line and you are riding a motorcycle in the eyes of the law, even if it still looks like a scooter.
Engine size alone does not always settle it: a scooter can have a 125cc engine and still be ridden on an entry-level licence in some places, while a faster machine triggers a higher category. So before you choose your licence, know which class your scooter falls into. If you are still deciding what to buy, our breakdown of 50cc versus 125cc scooters is a useful companion.
The United Kingdom: CBT, then a category
The UK has a clear, staged system. There is no single "scooter licence": you complete a training step, then earn a vehicle category that matches what you ride.
Compulsory Basic Training (CBT)
For almost every new rider, the journey starts with Compulsory Basic Training, universally called CBT. It is a one-day course at an approved training body covering the controls, off-road handling and a short period of supervised road riding. It is not a pass-or-fail exam: you complete it and receive a DL196 certificate.
That certificate lets you ride a 50cc moped from age 16, or a 125cc motorcycle on L plates from age 17, for up to two years before it expires. Before any of this you need a provisional driving licence, which costs 34 pounds online through the DVLA. CBT itself usually costs 130 to 170 pounds, depending on the school.
Category AM: 50cc mopeds, from 16
Category AM is the moped category, available from age 16. It covers two-wheelers with a maximum design speed between 25 and 45 km/h (around 28 mph), fitted with a petrol engine no larger than 50cc or an electric motor up to 4kW. For the full entitlement, and to ride without L plates, you complete CBT, pass the motorcycle theory test, then pass the practical test on a moped.
Category A1: up to 125cc, from 17
At 17 you can move up to category A1, which covers motorcycles and scooters up to 125cc and 11kW. The route is the same shape: CBT first, then the theory test, then a two-part practical test (Module 1 off-road, Module 2 on-road). Pass both and you can drop the L plates and carry a passenger. The official fees are modest: 23 pounds for the theory test, 15.50 pounds for Module 1, and 75 pounds for Module 2 on weekdays (88.50 pounds evenings and weekends).
Does a car licence already cover a moped?
This is the most misunderstood point in UK two-wheel law, and the answer hinges on one date. If you passed your car driving test before 1 February 2001, you have so-called grandfather rights: category P appears on your licence, and you can ride a 50cc moped with no L plates and no CBT. If you passed on or after 1 February 2001, your car licence does not include moped rights by default: you must complete CBT before you can legally ride a 50cc machine, and anything larger needs the relevant motorcycle category. In short, a modern car licence is not a free pass to a scooter.
The United States: it depends on your state
The United States has no national moped licence. Each state writes its own rules, ranging from "no licence needed at all" to "a full motorcycle licence, even for a 50cc." Roughly 44 of the 50 states require some form of licence to ride a moped or scooter on public roads, while about six do not. The practical pattern looks like this:
- True sub-50cc mopeds (low top speed, sometimes with pedals) often need only an ordinary driver's licence. Colorado, Connecticut, Illinois and Maine all accept a standard licence for vehicles that meet the moped definition.
- Faster scooters, and anything 50cc and above, usually require a motorcycle licence or endorsement (commonly a Class M). California is a strict example: a 50cc scooter needs an M1 motorcycle licence, not just a car licence.
- A handful of states require no licence for the smallest mopeds, though many still require registration, a helmet or insurance.
New York shows how granular this gets. It sorts mopeds into three classes by speed: Class C (under 20 mph) and Class B (20 to 30 mph) can be ridden on an ordinary driver's licence, while a faster Class A moped (30 to 40 mph) requires a Class M motorcycle licence or permit. The minimum riding age is most commonly 16, though a few states allow restricted operation from 14 or 15.
The takeaway for any American rider is unavoidable: check your own state's Department of Motor Vehicles before you ride. A scooter that is licence-free in Florida can require a motorcycle endorsement two states away, and helmet, registration and insurance rules vary just as widely.
How the two systems compare
| United Kingdom | United States | |
|---|---|---|
| Who sets the rules | National (DVLA / DVSA) | Each state separately |
| 50cc moped | Provisional licence plus CBT (category AM), from 16 | Often a regular driver's licence; some states need a motorcycle licence |
| 125cc scooter | CBT, theory test and two-part practical test (category A1), from 17 | Motorcycle licence or endorsement in most states |
| Compulsory training | Yes, CBT for almost all new riders | Varies; a safety course is sometimes required or waives a test |
| Typical minimum age | 16 (moped), 17 (125cc) | Usually 16, occasionally 14 to 15 for small mopeds |
| Rough entry cost | About 34 pounds provisional plus 130 to 170 pounds CBT | Modest state licence or endorsement fees, varies widely |
The practical steps to get licensed
Wherever you ride, the sequence is much the same:
- Confirm the legal class of your scooter. Check the engine size and maximum design speed, then match that to your local moped or motorcycle definition. This decides the rest.
- Check the rule for your exact location. In the UK, start at GOV.UK. In the US, go straight to your state's DMV page, because a neighbouring state's rules will not apply.
- Get the underlying licence or permit. A UK provisional licence, or whatever driver's licence your state requires before a moped endorsement.
- Complete any compulsory training. CBT in the UK, or a state-approved rider course in parts of the US, which sometimes also waives the riding test.
- Take the theory and practical tests for your category to ride without L plates or move up to a larger machine.
- Sort registration, insurance and a helmet before your first ride: separate from the licence, but just as legally important.
Once you are licensed, the next decisions are about the machine and the route. If you are weighing electric against petrol, our look at electric versus petrol scooters covers the trade-offs. And when you ride, a navigation app built for two wheels keeps you off roads your scooter is not allowed on. That is the gap Urban Rider was made to fill: iOS-first today, with an Android version in open beta, and smaller than the big mapping apps, but it starts from your vehicle rather than treating it as a car.
One last word: licensing rules change, so treat this as a starting map, not legal advice. Always confirm the current rule with GOV.UK or your state's DMV first.
Frequently asked questions
Can I ride a 50cc moped on a car licence in the UK?
It depends on when you passed your car test. If you passed your UK car driving test before 1 February 2001, you have category P on your licence and can ride a 50cc moped with no L plates and no CBT. If you passed on or after that date, your car licence does not include moped rights automatically: you must complete a one-day CBT course first, after which you can ride a 50cc moped on L plates.
What is the minimum age to ride a moped or scooter?
In the UK you can ride a 50cc moped (category AM) from 16, and a 125cc machine (category A1) from 17. In the United States the minimum age is set by each state and is most often 16, though a few states allow restricted moped operation from 14 or 15. Always check your own state because the rules vary widely.
Do I need a licence to ride a scooter in the United States?
In most states, yes. Roughly 44 of the 50 states require some form of licence to ride a moped or scooter on public roads, while around six do not. Many states accept an ordinary driver's licence for a true sub-50cc moped, but a faster scooter, or anything 50cc and above, usually needs a motorcycle licence or endorsement. California, for example, requires an M1 motorcycle licence for a 50cc scooter.
What does CBT cover, and how long does it last?
Compulsory Basic Training is a one-day UK course covering the controls, off-road handling and a short period of supervised riding on the road. It is not a pass-or-fail test: you complete it and receive a DL196 certificate. That certificate lets you ride a 50cc moped (from 16) or a 125cc motorcycle on L plates (from 17), and it is valid for two years. CBT typically costs between 130 and 170 pounds.
What is the difference between an AM and an A1 licence?
In the UK, category AM covers two-wheeled mopeds with a maximum design speed between 25 and 45 km/h (28 mph), with a 50cc petrol engine or up to 4kW electric, from age 16. Category A1 covers motorcycles and scooters up to 125cc and 11kW from age 17. To hold a full A1 licence you complete CBT, pass the motorcycle theory test, then pass the two-part practical test.
