If you have ever been handed a type approval certificate and wondered what actually happened inside the lab to produce it, this is the walkthrough. AIS-018 is not a long standard, but it is a specific one \u2014 it tells you exactly how many samples ARAI wants, what temperature the salt spray chamber runs at, and how many kilometres per hour of drift the test agency will tolerate before it fails your unit.<\/p>\n
Two documents do the work here. CMVR Rule 118 decides whether<\/em> a vehicle must be fitted. AIS-018 decides whether the thing you fitted is legal<\/em>.<\/strong> People collapse these into one idea and then get confused when a device passes one and fails the other.<\/p>\n If you are past the regulation and into procurement, our speed limiter device in India<\/a> page covers models, fitment and certification support. Everything below is the standard itself.<\/p>\n AIS-018:2001, titled Automotive Vehicles \u2013 Speed Limitation Devices \u2013 Specifications<\/em>, sets out the requirements, the methods of test, and the type approval procedure for speed limiters used on Indian vehicles.<\/strong><\/p>\n It is published by ARAI on behalf of the Automotive Industry Standards Committee, which sits under the CMVR Technical Standing Committee set up by the Ministry of Road Transport and Highways. So although you will hear people call it “the ARAI standard,” ARAI is the printer and one of the test agencies \u2014 the authority behind it is MoRTH.<\/p>\n The standard has been amended five times. Amendment No. 5, issued 19 December 2017, is the most recent and added an EMC requirement. That matters more than it sounds like it should, and I will come back to it.<\/p>\n The introduction to AIS-018 says it plainly: under CMVR Rule 118, transport vehicles notified by the Central Government must be fitted with a speed governor.<\/p>\n Rule 118 was amended by MoRTH notification G.S.R. 290(E) dated 15 April 2015<\/strong>. That amendment put the fitment obligation on the vehicle manufacturer, at either the manufacturing stage or the dealership stage.<\/p>\n Sub-rule (2) then hands State Governments a separate power \u2014 they can notify categories of transport vehicles registered before<\/em> 1 October 2015 that were never fitted, and require the operator<\/strong> to retrofit them.<\/p>\n This is why compliance responsibility feels split in practice. New vehicle, factory-fitted, manufacturer’s problem. Older vehicle, retrofit, your problem.<\/p>\n The preset speed is not something a fleet chooses. It is fixed by category. State transport departments reproduce the central position in their retrofit orders \u2014 the West Bengal Transport Department’s notification No. 2-WT\/3M-75\/2013, dated 4 January 2016, lists them like this:<\/p>\nAIS-018 is the standard a speed limiter has to be tested against before it can be fitted<\/h2>\n
Rule 118 is what makes fitment compulsory<\/h2>\n
Preset speeds are either 80 km\/h or 60 km\/h, and the category decides which<\/h2>\n
