Green Vehicle Laws and Regulations in New Jersey
New Jersey has numerous vehicle-related laws specific to protecting and improving the environment such as emissions test requirements (and exemptions for diesel-powered and electric vehicles), idling restrictions, fee assessments for gas guzzling vehicles, tunnel and bridge restrictions, low-speed vehicle regulations, and more. Read on for more on New Jersey's green vehicle laws and regulations.
New Jersey Vehicle Emissions TestsNew Jersey requires routine inspections, which only entail an emissions test. Unless your vehicle is exempt (see list below), you must take your vehicle to an inspection facility by the due date on your windshield sticker. Don't expect a reminder notice from the New Jersey Motor Vehicle Commission (MVC); The agency leaves it up to you to remember.
If your vehicle requires an emissions test, find the nearest inspection station with the locator widget at the bottom of this page. To learn about the inspection process and requirements, check out our page on NJ emissions testing.
Emissions Test Exemptions for Fuel-Efficient Cars
New Jersey exempts the following fuel-efficient vehicles from emissions tests:
- Vehicles fueled 100% by electricity (EV).
- Diesel-powered vehicles* that are either:
- Required to be owner- or lessee-inspected and have a gross vehicle weight rating (GVWR) of 8,501 pounds to 17,999.
- Model-year 1996 and older and also plated passenger, not for profit, governmental, commuter van, farmer or farm truck (not including buses).
- Bearing a GVWR 8,501 to 17,999 lbs. and also plated passenger, not for profit, governmental, commuter van, farmer or farm truck (not including buses).
*NJ requires an annual smoke emissions test for all heavy-duty diesel vehicles with a GVWR of 18,000 lbs. or more.
Emissions test exemptions are just one perk of going green. For more on time- and money-saving bonuses, check out our page on eco-friendly driver incentives. To see the full list of vehicles exempt from inspection, consult the New Jersey MVC.
New Vehicle Fee and Exemptions
New Jersey charges an additional fee for buying or leasing a new passenger vehicle that either:
- Has a 19 MPG (miles per gallon) or less Environmental Protection Administration average fuel efficiency rating.
- Has a sale or lease price* of $45,000 or more (*prior to any rebate or trade-in that drops the price below $45,000)—unless it either:
- Has a 40 MPG or higher EPA average fuel efficiency rating.
- Qualifies as a zero-emission vehicle (ZEV).
You must pay this fee to the New Jersey Motor Vehicle Commission whether you lease or buy your new automobile either in New Jersey or beyond state lines. Calculate it by multiplying the sales or lease price (before any rebate or trade-in credits) by 0.4%. For example, the fee for a new car costing $45,000 is $1,800.
Keep in mind this fee is in addition to what you'll pay to register your vehicle in NJ, and must be separately listed on your bill, receipt, or invoice by the seller. However, the fee is not subject to retail sales tax.
To get the specifics, including where to pay the fee, what to do when buying an out-of-state vehicle, and what qualifies as a ZEV, refer to New Jersey Permanent Statutes 39:3-8.4.
New Jersey Vehicle Idling Restrictions
NJ's idling restrictions vary depending on whether the vehicle is powered by gasoline or diesel fuel. Read on for specifics.
Gasoline-Powered Motor Vehicles
If your gasoline-powered vehicle is not in motion, New Jersey prohibits it from idling for more than 3 consecutive minutes. A few exceptions include:
- Idling in traffic or while waiting in a line of motor vehicles (school buses excluded).
- Vehicles with a primary or secondary power source not made for propulsion, such as those that operate lift gate pumps and control car temperature (excluding heating or air conditioning the passenger compartment).
- Undergoing or (waiting to undergo) state or federal inspection.
You can find full details on gas-powered vehicle idling restrictions and exceptions under New Jersey Administrative Code 7:27-15.8.
Diesel-Powered Motor Vehicles
As with gas-powered vehicles, New Jersey also prohibits diesel-powered vehicles from idling for more than 3 consecutive minutes (when not in motion). However, you can get around this provision when:
- The ambient temperature falls under 25º Fahrenheit and you've stopped your vehicle for 3 hours or more. Under these circumstances, it may idle for up to 15 consecutive minutes.
- You are actively picking up or dropping off passengers in a diesel bus. Under these circumstances, it may idle for 15 consecutive minutes in a period of 60 minutes.
There are numerous exceptions. Some include when your vehicle is:
- Stuck in traffic that renders it intermittently motionless.
- Actively performing emergency services (fire, police, public utility, military tactical, and snow removal vehicles, to name a few).
- Is actively being repaired or serviced (given that running the engine is necessary).
- Undergoing or (waiting to undergo) state or federal inspection.
For a full list of exceptions, and more info specific to diesel-powered vehicle idling, consult New Jersey Administrative Code 7:27-14.3.
Low-Speed Vehicle (LSV) Requirements and Restrictions
LSV Operating Requirements
New Jersey requires low-speed vehicles to be:
- Registered (no vehicle inspection required).
- Insured (either through the New Jersey Personal Insurance Plan (NJPAIP) or other voluntary providers).
- Operated by a person who is validly licensed to drive an LSV.
Besides not having to get your LSV inspected, you must abide by all other NJ traffic laws. For more guidelines and additional info on titling and registering, license plates, insurance requirements, and federal and state requirements, consult the MVC's Low Speed Vehicles page.
LSV Operating Restrictions
New Jersey permits low-speed vehicles on local roads with a posted speed limit of 25 MPH (miles per hour) or fewer. However, if a municipality, county, or Department of Transportation deems it safe, you can drive an LSV on roads that do not exceed 35 MPH. Keep in mind, there are even more LSV driving regulations you can access online.
What is a Low-Speed Vehicle
New Jersey defines a low-speed vehicle as:
- Having 4 wheels.
- Capable of traveling 20 MPH (but not more than 25 MPH) on a level surface.
- Not fueled by gas or diesel fuel.
- Compliant with the federal safety standards spelled out in Title 49 of the U.S. Code of Federal Regulations, section 571.3(b).
