Editing Nitrous oxide engine (section)

==Street legality==
Nitrous oxide injection systems for automobiles are illegal for road use in some countries. For example, in [[New South Wales]], Australia, the [[Roads & Traffic Authority]] Code of Practice for Light Vehicle Modifications (in use since 1994) states in clause 3.1.5.7.3 that "The use or fitment of nitrous oxide injection systems is not permitted."<ref>{{cite book

In Great Britain, there are no restrictions on the use of {{chem|N|2|O}}, but the modification must be declared to the insurance company, which is likely to result in a higher premium or refusal to insure.

In Germany, despite its strict [[TÜV]] rules, a nitrous system can be installed and used legally in a street driven car. The requirements for the technical standard of the system are similar to those of aftermarket [[Natural gas vehicle|natural gas conversions]].
