Inspection Due Check
How it works

The right inspection depends on the right details.

Inspection requirements are matched to the registration place, transaction, vehicle, and date you choose. We show an answer only when official sources cover the details you selected.

The decision path

From your selections to a sourced answer

  1. Choose the place and date.Confirm the registration state, official program area, and date that applies.
  2. Add the vehicle and transaction.Enter only the details that can change the requirement.
  3. Compare each inspection separately.Safety, emissions, and identity rules can have different triggers and exemptions.
  4. Review the supporting details.See the reason, timing, fees, documents, next step, and official sources beside the answer.
Details and safeguards

Why an answer may be unavailable

“Not required” must be supported just as carefully as “required.” Missing evidence is never turned into a negative answer.

Which official sources we use

We use the official source that directly addresses each requirement. An emissions-area source, for example, does not establish a separate safety or VIN requirement.

  1. Current statute or administrative rule when readable and directly controlling.
  2. Current official DMV, DPS, DEQ, or program guidance.
  3. Official fee, exemption, waiver, retest, or station page.
  4. Officially designated program operator, with that designation recorded.
  5. EPA context for discovery, never as a replacement for current state rules.
What “cannot determine” means

The checker uses this result when a controlling fact is missing, the program area is unclear, official sources conflict, an official page is unavailable, or the selected vehicle or transaction is not covered. The best official next step remains visible.

How dates and geographic boundaries work

A rule begins on its official start date and stops before any stated end date. Model-year, rolling-age, and GVWR limits are applied exactly as published. Future rules do not activate early.

State and program sources define county or program-area membership. A ZIP may suggest a county, but never confirms a final answer where boundaries cross it.

How answers stay current

We compare each answer with current official sources, including dates and important boundary cases. If a controlling source changes or conflicts with another official source, the affected answer becomes unavailable until it can be confirmed.
