NYC Tow Truck Endorsement Practice Exam

How does an Underlift function?

1. It secures the front bumper of the towed vehicle.

2. It lifts one end of the towed vehicle from under the axle.

3. It prevents the towed vehicle from rolling away.

4. It locks the wheel of the towed vehicle in place.

The correct answer is: It lifts one end of the towed vehicle from under the axle.

The Underlift functions by lifting one end of the towed vehicle from under the axle, which is essential for towing. This method allows for the suspension of the vehicle to remain intact while providing a secure and stable lift. By lifting from under the axle, the weight distribution is managed effectively, which helps prevent damage to either the towed vehicle or the tow truck during transport. This is particularly important for vehicles that are low to the ground or have special suspension systems, as it avoids unnecessary strain and maintains the integrity of the towed vehicle throughout the towing process. In contrast, the other options focus on actions not characteristic of how an Underlift operates. For instance, securing the front bumper, preventing rolling, or locking wheels pertains to different towing techniques and safety measures rather than the specific function of an Underlift.
