Line 6:
'''Curb weight''' (American English) or '''kerb weight''' (English) is the total mass of a vehicle with standard equipment and all necessary operating consumables such as [[motor oil]], transmission oil, [[brake fluid]], [[coolant]], air conditioning refrigerant, and sometimes a full tank of fuel, while not loaded with either passengers or cargo. The [[#Gross vehicle weight rating|gross vehicle weight]] is larger and includes the maximum payload of passengers and cargo.<ref>{{cite web|title=Curb Weight vs Gross Vehicle Weight – CarsDirect|url=https://www.carsdirect.com/car-safety/curb-weight-vs-gross-vehicle-weight}}</ref>
 
This definition may differ from definitions used by governmental [[regulatory agency|regulatory agencies]] or other organizations. For example, many [[European Union]] manufacturers include the weight of a {{convert|75|kg|lb|adj=on}} driver and luggage to follow European Directive 95/48/EC.<ref>{{cite web | url=http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:31995L0048:EN:HTML | title= EU Commission Directive 95/48/EC | publisher = [[European Commission]] | access-date=4 January 2009 }}</ref> Organizations may also define curb weight with fixed levels of fuel and other variables to equalize the value for the comparison of different vehicles. The EU-directive actually defines Mass in running order, not curb-weight. Mass in running order is without the 75kg driver mentioned obove. Definition of mass in running order stated in the directive.
 
The United States Environmental Protection Agency regulations define curb weight as follows: Curb weight means the actual or the manufacturer's estimated weight of the vehicle in operational status with all standard equipment, and weight of fuel at nominal tank capacity, and the weight of optional equipment computed in accordance with §86.1832–01; incomplete light-duty trucks shall have the curb weight specified by the manufacturer.<ref>{{Cite web|url=https://www.law.cornell.edu/cfr/text/40/86.1803-01|title=40 CFR § 86.1803-01 – Definitions.|website=LII / Legal Information Institute|language=en|access-date=20 April 2020}}</ref>
