Hawaii General Emissions Information

Hawaii General Emissions Information

Currently, there are no emissions standards and tests for vehicles in the state of Hawaii. The air quality of Hawaii is pretty clean other than the volcanic “vog” that is in the air. Honolulu is constantly ranked among one of the cities with the least ozone air pollution.

Also, many people choose to rely on scooters and mopeds and tend to live on the low emission side most of the time. Gas prices are extremely high and people avoid using gas powered vehicles due to this reason unless there is a necessary reason that they need one.

Safety Inspections

Safety inspections are required in the state of Hawaii and you will need a sticker when driving a passenger vehicle, motorcycle, or light truck.

Registration is required annually and you must first pass a safety inspection before you’re able to renew your vehicle each year. You can have this inspection completed at your local Hawaii’s DMV office or at an authorized safety inspection location in your county.

Your Hawaii County clerk will be able to give you information regarding vehicle inspection hours and locations. Below are some of the things that you should have when you’re having your inspection complete:

  • Proof of Your Car Insurance Policy
  • Proof of Your Vehicle Registration
  • Payment for the Safety Inspection

After your vehicle passes inspection, the information about your vehicle is likely to be updated electronically in the state database and you will be provided with a safety inspection certificate.

Hawaii Safety Inspection Details

Below are the items that your inspection technician will check during the inspection:

  • The Body, Fenders, and Bumpers of Your Vehicle
  • Wiring and the Battery
  • the Suspension and Brakes System
  • the Door, Hood, Trunk Latches and Other Components
  • the Drivetrain
  • Exhaust Systems As Well As Fuel and Intake Systems
  • Mirrors, Lamps, and Reflectors
  • Restraint Systems, such As Seatbelts
  • Tires and Wheels

If the components above do not function or if they appear to be damaged, it is likely that your vehicle will not pass the safety inspection.

The safety inspection technician will also verify certain information regarding your vehicle visually, such as your car insurance information, your license plate, and your vehicle identification number.

Hawaii Incentives for Eco-Friendly Driving

Although there are no requirements for being an emissions test, you may be able to take advantage of some eco-friendly tax breaks and auto insurance discounts. Some of these perks are offered by the federal government and are put in place to encourage drivers to be more conscious of what they are doing to the environment when they drive their vehicles.

The state of Hawaii also offers an electric vehicle incentive for vehicles that have four or more wheels, runs off of a battery that stores a minimum of four hours of energy, and is powered by a rechargeable battery that draws electricity from an external source.


Maintaining a green vehicle is important in the state of Hawaii and many insurance companies award those who practice eco-friendly driving. You should check with your insurance provider to see if you can also receive a discount on your insurance for your green car.
