An ultra-low-emission vehicle (ULEV) is a motor vehicle that emits extremely low levels of motor vehicle emissions compared to other vehicles. In some jurisdictions it is defined in law; low and ultra low emission vehicles may be given tax or other advantages, [1] while high emission vehicles may suffer restrictions or additional taxation.
A low-emission zone (LEZ) is a defined area where access by some polluting vehicles is restricted or deterred with the aim of improving air quality.This may favour vehicles such as bicycles, micromobility vehicles, (certain) alternative fuel vehicles, hybrid electric vehicles, plug-in hybrids, and zero-emission vehicles such as all-electric vehicles.
A low-emission vehicle is a motor vehicle that emits relatively low levels of motor vehicle emissions. The term may be used in a general sense, but in some countries it is defined in air quality statutes. Different groups of people ("go greens", "go with the flow" and "no greens") show different interest in low emission vehicles [1]
Petrol-powered vehicles are exempted from particulate matter (PM) standards through to the Euro 4 stage, but vehicles with direct injection engines are subject to a limit of 0.0045 g/km for Euro 5 and Euro 6. A particulate number standard (P) or (PN) has been introduced in 2011 with Euro 5b for diesel engines and, in 2014, with Euro 6 for ...
A partial zero-emission vehicle, in the United States, is an automobile that has zero evaporative emissions from its fuel system, has a 15-year (or at least 150,000-mile) warranty on its emission-control components, and meets SULEV tailpipe-emission standards.
The SULEV standard is stricter than the standard for LEV (low emission vehicle) and ULEV (ultra-low-emission vehicle), however not as strict as PZEV (partial zero-emissions vehicle) which meets the SULEV standard for tailpipe emissions, but has zero instead of reduced evaporative emissions.
Vehicles in the "disabled" tax class are exempt from the charge, as are London-licensed taxis, private hire vehicles which are wheelchair accessible, and historic vehicles (over 40 years old). There are also exemptions for agricultural vehicles, military vehicles, certain types of mobile cranes and non-road going vehicles which are allowed to ...
The country in which a motor vehicle's vehicle registration plate was issued may be indicated by an international vehicle registration code, also called Vehicle Registration Identification code or VRI code, formerly known as an International Registration Letter [1] or International Circulation Mark.
