  1. What does the oil pressure warning light indicate when it illuminates while driving?

    Answer: The engine oil pressure is critically low

    The oil pressure warning light means engine oil pressure has dropped dangerously low — stop driving immediately to avoid severe engine damage.

  2. How often should you check your tire pressure?

    Answer: At least once a month and before long trips

    Tire pressure should be checked at least monthly and before long trips since tires lose pressure naturally and temperature changes affect pressure.

  3. What is the minimum legal tire tread depth required in Texas?

    Answer: 2/32 inch

    Texas law requires tires to have at least 2/32 inch of tread depth to be considered legal for road use.

  4. When should you replace your windshield wipers?

    Answer: When they leave streaks, skip, or squeak during use

    Wipers should be replaced when they leave streaks, skip across the windshield, or squeak, all of which indicate deteriorated rubber.

  5. What does a temperature gauge reading in the red zone indicate?

    Answer: The engine is overheating

    A temperature gauge in the red zone indicates the engine is overheating, requiring immediate action to prevent serious damage.

  6. How should you properly check your engine oil level?

    Answer: Check it when the engine is cold or has sat off for several minutes

    Oil should be checked when the engine is cool or has been off for a few minutes so oil drains back into the pan for an accurate dipstick reading.

  7. What is the primary purpose of coolant (antifreeze) in your vehicle?

    Answer: To regulate engine temperature and prevent both freezing and overheating

    Coolant regulates engine temperature by carrying heat away from the engine and preventing the water in the cooling system from freezing or boiling.
