What is the primary difference between Level One and Level Two DOT inspections?

• A. Level One includes under-vehicle inspection; Level Two does not
• B. Level One inspects only the driver; Level Two inspects the vehicle
• C. Level One is less thorough than Level Two
• D. Level One is conducted by non-DOT personnel

Answer: (A)

Level One is the more thorough inspection that tests both the driver and the vehicle in detail, including a complete look under the vehicle. The undercarriage is part of this inspection, so inspectors check components you can’t see from the outside, looking for issues like leaks, worn parts, or hidden problems. Level Two is a shorter walk-around inspection that focuses on the exterior and obvious safety items, and it does not include the under-vehicle portion. Because Level One covers more ground and requires more time and access to the vehicle’s underside, it’s the deeper, more comprehensive check, while Level Two is quicker and roadside-friendly. The other options don’t fit because Level One is not limited to only the driver, is more thorough (not less), and is conducted by DOT-trained personnel, not non-DOT staff.
