Q: Can I ride a Trike with my licence???????
have been told by my father and a few close friends that I can ride
a trike (motorbike derived) on a provisional car(cat:B)/motorbike(cat:A)
licence, as long as I display 'L' plates, on my own. Something about
a motorcycle and sidecar outfit being able to ride a bigger bike without
Trikes and UK Law
Are There Different Types Of Trike?
Yes, but in a nutshell, there are only two types of trike that you really need to know about, bike engined and car engined. Having said that, it isn't the engine type that finally influences the decision of what type of trike you're going to ride, it's the weight of the trike, and what you are actually licensed to ride; any type of trike can be built or bought to suit disabled needs. These can realistically vary from a humble 250cc bike engined trike, all the way up to a growling, car engined V12 monster.
How Much Does A Trike Cost?
How long is a piece of string? If you're thinking of building a trike yourself, then there really are no price guidelines I can give you; the sky's the limit as they say. If you're going to buy a ready made trike, whether it be bike or car engined, second hand or new, you can be sure to be looking at anywhere between ?1,000 and ?20,000, depending on how many "trick" or "shiny" bits you want on it, or indeed, the extent of the disabled adaption. The adaption can be anything from a linked brake system, to a trike design where it is possible to board the trike in a wheelchair, and steer the trike from said chair; the possibilities are endless.
I Want To Build A Trike ... What's This SVA Scheme I've Heard About?
The Single Vehicle Approval scheme is a pre-registration inspection for cars and light goods vehicles that have not been type-approved to British or European standards, including amateur-built vehicles and vehicles using parts from previously registered vehicles; this can include some trikes. The main purpose of the scheme is to ensure that these vehicles have been designed and constructed to acceptable safety and environmental standards before they can be used on public roads. If you're seriously considering building your own trike, a copy of the SVA manual would be more than helpful to you. Go here ...

Is A Trike Classed As A Motorcycle Or A Motorcar?
Now this is where it gets complicated. In this section, I will deal with vehicle classification, driving licence groups, MOT testing classes, and vehicle excise licence. These four different categories, when used in conjunction with each other, help determine what type of trike you've got, or are thinking of buying/building, and indeed, whether you are actually licensed to ride it or not. Please note that you will see several weights and figures which, logically speaking, should be the same in different categories, but they aren't. Don't despair, these figures *are* correct, as I ... er, asked a policeman. I'll start with vehicle classification :-
A mechanically propelled vehicle that is used, adapted or intended for use on the road, is classified under a series of groups according to its use, weight and design. A trike can be in a number of classifications, and depending on which one it's in, makes for some pretty fundamental differences when applying road traffic law. The groups are as follows ...
1. Invalid carriage - Not exceeding 254
kg - Designed for sole use by the disabled. 
3.Motorcar - Not exceeding 3050kg - Passenger carrying with no more than 7 seats excluding the driver.
 If a trike was built solely for a disabled person, and was adapted as such, it could be classified as an invalid carriage. It would be prohibited from using a motorway, would require only a "K" driving licence group, and would be excluded from road tax if under 10cwt unladen weight.
What your trike is classified as, will denote which driving licence you will require, and what vehicle excise licence your trike will require.
Now, I'll move onto :-
Driving Licence Groups
So, now you've worked out what your trike is classified as, you need to make sure that you are licensed to drive the vehicle. Unfortunately, licence groups don't match vehicle classifications exactly, so here we go ...
1. Motorcycle - New licence holders are
limited to 25kw/33bhp for the first two years of their licence, unless
they take the large motorcycle test (Direct Access). Less than 410kg
If you've passed a full motorcycle test, you will have group "B1" on your licence, although if you haven't passed a car test, you wont have group "B". This creates a bit of an anomaly as your motorcycle can't exceed 410kg, but you could ride a trike up to 550kg, because of your "B1" entitlement. This is worth knowing, as there are quite a few riders who limit themselves to a trike under 410kg without realising.
Changes to B1 Entitlement.
Before October 2000, a person who passed a motorcycle test was granted a full sub-category B1 licence (lightweight car, motor quadricycle, motor tricycle) as an additional entitlement with the full A (motorcycle) licence. The Driving Standards Agency, in their 'Safer Motorcycling' consultation, proposed that in future successful motorcycle test candidates would be issued with a provisional rather than a full B1 licence. 49 of the 57 consultees who commented on the issue were in favour of this proposal, including safety, police and training interests. There were representations against from companies selling lightweight cars, the National Trike Register and MAG UK, suggesting that riders might want to use their licence to ride tricycles. There were suggestions that separate licence categories should be introduced, but changes to motor vehicle licence categories would require a change to EU law. Ministers decided to implement the proposal, which affected very few motorcyclists as over 90% held a full car licence (which continues to give full sub-category B1 entitlement). Nor did it affect anybody already holding a full motorcycle licence, who retained full B1 entitlement. The changes were implemented during October 2000. What the above did mean though is that if you didn't have a full car or bike licence before October 2000 and wish to either trike your bike or buy one you will now have to apply for a provisional car licence and if you wish to carry passengers then pass the test. This is very unfair as a car driver with no experience of bikes can get straight onto certain types of trike, with passengers, and ride away. Also if you're forced onto a trike due to a disability or a smash you'll have to apply for a provisional car licence even though you've been riding bikes for years!
You can ride a trike on a provisional car licence, ie. with "L" plates, but you must be 17 ( or 16 if you are getting Disability Living Allowance at the higher rate for the mobility component ) and the trike must have only one seat; the rider's seat. If you do wish to carry passengers, your trike can have extra seats, but you must carry a qualified bike or car licence holder with you at all times; this is also dependant, of course, on which sort of trike your accompanying full licence holder is qualified to ride.

Confused yet? You will be :-
MOT Testing Classes
Just to make things even more complicated, and having worked out your trike's classification, *and* ensured you are licensed to ride it ... what MOT group is it in? It could make a difference when it comes to MOT time, and you suddenly find out that your local bike workshop isn't entitled to test it. The requirement for an MOT test is the same for all vehicles, including trikes, but excluding HGVs and PSVs.
Class 1 - Motorcycles - With or without
sidecars up to 200cc.
If you're wondering why I've included this table, then look again at class 3. Say for example, you've got a trike of between 450kg and 550kg (B1 licence maximum), it will need to be tested at a class 4 MOT centre. So, your trike could be classed as a motorcar, yet you're riding it under a quadracycle licence, but you need to get it tested at a car MOT centre. Got it? Good!
And finally in this section :-
Vehicle Excise licence
Just to make sure it doesn't get too easy for you, your trike will be taxed under one of three classes. Where as previously your trike would have been taxed as either a PLG vehicle (private light goods), or a motorcycle, a new rate was introduced on 1/6/99, as a concession for smaller engines ...
Part 1 - General rate - (PLG).
Expect to see "Tricycle" instead of "Bicycle" on your tax disc, if your trike falls into the relevant class [Part 2].
Spot the anomaly again. Say for example, you've got a trike weighing 420kg, it's not a motorcycle under vehicle classifications, it's a motorcar, but you're riding it under a "B1" (quadracycle) licence. It's tested at a class 3 MOT centre, but it qualifies as a motorcycle for vehicle excise licence.
Vehicle Excise Rates As Of 01/10/00
Bicycles/Tricycles - 12 month rate:-
Motorcycles (with or without sidecar)
not over 150cc = ?15.00
You'll notice that there is no "150cc to 250cc" rate of ?40.00 for trikes, presumably because not many trikes fall into that rate, but as we all know, there are trikes that exist of that engine capacity. Ah well, you'll just have to pay the full amount, same as the rest of us.
So, that's it ... easy, eh? All you have to do now, is work out where your trike comes in all this. The best of British luck to ya!
Do I Need To Wear A Helmet When Riding A Trike?
In a word, "No", neither for bike engined nor car engined trikes. Helmets are only compulsory for motor bicycles, not motor tricycles. On the other hand, you may wish to wear a helmet, say on a long journey, to protect your head from the weather, flying debris etc, etc; it's up to you. As a word of warning, should you be unfortunate enough to have an accident on your trike, some insurance companies may try to use against you, the fact that you weren't wearing a helmet should you wish to make a claim for damages, especially if you sustained head injuries.
As far as 'the boys in blue' are concerned, do no more than to print this next piece out, and carry it with you. If you get pulled and quizzed about your lack of lid, just show this to them. Do not alter it in any way, as it is an official police document and will be recognised as such.

Do I Need Seatbelts Fitted To My Trike?
This is the definitive guide to seatbelt requirements for trikes; except no imitations! This took some serious research, and a few arguments with the Vehicle Inspectorate, but they agree this is totally correct.
Vehicles first used before 1 April 1987.
Seatbelts are required for three wheelers that fall into the following categories:
1. With an unladen weight over 410Kg first used on or after 1 January 1965. 2. With an unladen weight over 255kg if first used on or after 1 September 1970.
Less than 410kg unladen equipped with a driving seat of a type that requires the driver to sit astride it and where that vehicle was constructed or assembled by a person not ordinarily engaged in the trade or business of constructing those sort of vehicles.
Vehicle first used before 1 April 1981:-
Drivers - A belt that restrains the upper body (but need not include a lapbelt). Forward facing rear seats - no requirement.
Vehicle first used after 31 March 1981:-
Drivers - a 3 point (lap/diagonal) belt.  Forward facing rear seats - no requirements.
Vehicles first used after 31 March 1987:-
Seatbelts are not required for trikes that either ...
1. Have an unladen weight of less than 255kg. 2. With an unladen weight of more than 255kg but less than 410kg which are equipped with a drivers seat requiring the driver to sit astride it and where its been constructed or assembled by a person not ordinarily engaged in the trade or business of manufacturing vehicles of that type.
Drivers - three point belts Forward facing rear seats ... If not more than 2 rear seats then either:-
1. A 3 point inertia belt for at least
1. restrains the upper and lower parts
of the torso.
