What Does an Illinois Car Inspection Entail?

All gasoline-powered vehicles from model years 1996 or later qualify for testing once they reach four model years old.

Some vehicles such as diesel-powered vehicles and antique vehicles are exempt from these emissions testing requirements.

An emissions test checks to ensure a vehicle is not leaking harmful substances into the environment or endangering the health and safety of the public. The Illinois Environmental Protection Agency handles vehicle emissions testing and testing guidelines for Illinois. Generally, an emissions inspection aims to look for any signs of damaged systems, leaks, fuel consumption, and emissions quality.

Who Conducts Vehicle Inspections in Illinois?

An Illinois driver cannot simply visit any mechanic or body shop for a vehicle inspection. Only authorized testing locations qualify to conduct official vehicle inspections.

Proper regular maintenance and safe driving can reduce the chances of a driver needing costly repairs and replacement parts to meet inspection requirements. Wear-and-tear will eventually degrade some of a vehicle’s systems, so all drivers should expect to eventually encounter repair costs. While vehicle repairs can be costly, a typical inspection fee is less than $100. However, the driver may need to pay for repairs and replacement parts if his or her vehicle fails inspection. Voluntary smog testing in Illinois incurs a $20 fee.

Illinois drivers must still meet their inspection requirements even if they are outside the state for an extended time. However, it is possible to secure a temporary exemption for one inspection cycle under certain circumstances. If a driver has an out-of-state registration and is only in Illinois temporarily, the driver does not need to worry about emissions inspections.

One final note for Illinois drivers concerning state inspections pertains to notices. The state sends notices to drivers informing them of their next required testing date. If a driver arranges for an emissions inspection outside of the designated timeframe, he or she may not meet the requirements for the next inspection cycle and require a second inspection.
