Why should a driver conduct a complete pre-trip inspection of a passenger vehicle before every trip, not just periodically?

Pick an answer

1. Pre-trip inspections are required only once a week for passenger vehicles
2. Passenger vehicles are exempt from the standard pre-trip inspection requirement
3. Inspections are necessary only after the vehicle has been serviced by a mechanic, since a defect is assumed to appear only after that kind of work
4. A defect that develops between trips could directly endanger passengers if not caught before departure
