Is the use of nitrous oxide road legal?
There is no law that prohibits the use of n2o injection on road vehicles. Our own cars are used on the road and the police confirm that they know of no law that we could be breaking. However you should inform your insurance company, depending on the type of wording of the policy, if you have problems phone privilege insurance on 0870 243 5555. The same applies to all types of tuning, and should be reported to your insurers.
