Travel Included Within 100 Miles

Distance is calculated from our Three Rivers, California service base using the shortest practical routed road distance to your exact testing address — never straight-line distance, and never a county-wide or ZIP-code estimate.

Travel Included Within 100 Miles

0–100 one-way routed road miles

  • No mileage charge
  • No travel charge
  • No dispatch or mobilization fee
  • No appointment minimum for smoke-opacity testing
  • The $250 minimum OBD service call still applies

There is no additional mileage or travel charge for testing locations within 100 one-way road miles of our Three Rivers service base.

Beyond 100 One-Way Road Miles

More than 100 one-way routed road miles

  • $0.65 per round-trip routed road mile
  • Applied to the full round-trip distance
  • No separate dispatch or mobilization fee
  • No additional appointment minimum

For locations more than 100 one-way road miles from our service base, a travel charge of $0.65 per round-trip routed road mile applies.

Appointments beyond 100 one-way road miles are scheduled after a routed distance review and written confirmation of the travel charge.

If your address falls near the 100-mile included-travel boundary, the routed distance returned at the time we prepare your written quote is what governs. Once the written quote is issued, that travel charge applies to that visit.
