* **New Vehicle Exemptions**: New vehicles are exempt for their first three registrations.
* **Hybrid Advantage**: Hybrid electric vehicles get a five-year exemption from smog checks.

# Preparing for Your Las Vegas Smog Check

While smog checks are not guaranteed to fail, some simple steps can increase your chances of passing on the first attempt:

* **Routine Maintenance**: Regular maintenance, including oil changes and air filter replacements, keeps your engine running smoothly and reduces emissions.
* **Check Engine Light**: A lit check engine light is a red flag for potential emissions issues. Get it checked by a mechanic before your smog check.
* **Warm Up Your Engine**: Take your car for a 15-minute drive before the test to ensure the engine reaches operating temperature for optimal performance during testing.
# What Happens During a Las Vegas Smog Check?

The smog check process is straightforward:

1. **Documentation**: Bring your vehicle registration and proof of insurance to the testing station.
1. **Test Type**: For vehicles manufactured in 1996 or later, the technician will likely use an On-Board Diagnostics (OBD II) test, which electronically checks your vehicle's emissions control systems for proper function.
1. **Pre-1996 Vehicles**: Older vehicles may undergo a two-speed idle test, measuring emissions at idle and higher RPMs.
1. **Pass or Fail**: The technician will inform you of the test results. Passing allows you to register your vehicle, while failing requires repairs and a retest.
# Failing the Smog Check? Don't Panic!

If your car fails the smog check, you have options:

* **Repairs**: Address the identified issues and get a repair receipt from an authorized facility.
* **Smog Check Waiver**: Nevada offers a waiver program if repairs exceeding $450 fail to resolve the emission problem.
