Just found this on UKpoliceonline.co.uk and thought it may be of interest;
The legality of nitrous use on the road varies from country to country, even within the EU. However, contrary to what many people believe (including some police officers) nitrous oxide injection is legal for road use in the UK and many other countries (just as are turbo chargers and superchargers). According to the Ministry of Transport, the Highway Code and the MOT handbook there is no law prohibiting the use of nitrous injection. However just as with any tuning modification, the owner must inform their insurance company and obtain adequate cover otherwise any performance modification would be illegal. Therefore the only way you will break the law by having your street car fitted with a nitrous kit in the UK, is if you fail to inform your insurance company that you have one. Insuring a nitrous injected vehicle has become easier since WON joined forces with Adrian Flux to provide all their customers with a better chance of obtaining adequate insurance cover. Some other insurance companies such as Greenlight Insurance also offer cover for nitrous equipped cars.
There is a degree of confusion over the need to have a hazard warning sticker on the outside of the car. nitrous oxide is neither a flammable nor a hazardous gas but it is an oxidiser. There is a legal requirement for commercial vehicles to display a suitable sticker but this does not apply to private vehicles, which are not even obliged to display a green compressed gas sticker. However, displaying such a warning sticker might well be advantageous to you and the emergency services if you were to be involved in any kind of accident, as this would inform them that you were carrying a container of compressed oxidiser.
