Are you thinking of getting or renewing a vehicle inspection? Driving without one can not only get you charged with a misdemeanor but also a hit to your wallet.
Depending on where you live, you might be required to get it done yearly or biannually. To ensure you stay legal on the road and pass the test, we’ve got everything you need to know about smog checks and how long does a smog test take. Keep reading to find out!
How Long Does a Smog Test Take?
During the smog test, the technician will inspect the vehicle for any signs of tampering with the emissions system. They will also check to make sure that the emission levels are in line with the state’s standards.
A smog test typically takes around 20-30 minutes to complete. However, it can vary based on several factors:
Type of Test
It depends on the type of smog test that a vehicle needs. Tailpipe emissions tests involve measuring the vehicle’s emissions directly from the vehicle’s tailpipe. It usually takes around 15 to 30 minutes.
Onboard Diagnostics (OBD) test checks the vehicle’s emission control systems using data from the OBD system. It’s generally quicker, often taking about 5 to 15 minutes.
Testing Facility Efficiency
Some smog testing centers are more efficient than others. This can impact the overall testing time. Larger and better-equipped facilities might have multiple testing lanes and trained personnel, allowing them to process vehicles more quickly.
The condition of your vehicle’s emissions control system and overall engine health can influence testing time. If the vehicle maintenance is up to date and is in good working order, the test should not take too long. Conversely, if your vehicle has issues with emissions components, it might take longer to diagnose and potentially fail the test.
Depending on the number of vehicles ahead of you in line at the testing facility, you might experience some waiting time. It is important for customers to call ahead to get an estimate of test wait times so they can plan their visit accordingly.
Generally, wait times are shorter during the week and longer on weekends and holidays. It’s a good idea to plan for this potential delay.
To expedite the process, ensure that your vehicle is ready for testing. Make sure the “Check Engine” light is not illuminated and that your vehicle has had a recent tune-up if needed.
Duration of a Typical Smog Test
So, how long does a smog test take? On average, a smog test takes around 20-30 minutes to complete. However, it’s wise to plan for a potential wait and allocate some extra time, especially during busy periods or if you’re going to a new testing facility.
Remember that these times are approximate averages and can vary. It’s always a good idea to contact your local smog testing center for more accurate information based on their specific procedures and workload.
