Human: How do I know if I should get my car inspected? Assistant: 
You should get your car inspected regularly, depending on the age and condition of the vehicle. Generally, you should have it inspected every 12 months or 24,000 miles, whichever comes first. If you notice any strange noises coming from your engine, or if your car has been acting strangely, then you should take it to a mechanic as soon as possible for an inspection.
