Final answer:
Flat towing is when the vehicle being towed is off the ground and all four wheels remain on the ground. This method is commonly used with recreational vehicles to tow a smaller vehicle for transportation at destinations. Dolly towing, wheel-lift towing, and off-road towing are not the correct terms for this method of towing.
Step-by-step explanation:
When the vehicle being towed is off the ground, this is called Flat towing. In flat towing, also known as dinghy towing, the towed vehicle is connected to the towing vehicle with a tow bar or tow dolly, and all four wheels of the towed vehicle remain on the ground.
Flat towing is commonly used for recreational vehicles (RVs) or motorhomes, where a smaller vehicle is towed behind the RV to provide transportation at the destinations. This method allows the towed vehicle to be easily maneuvered, as it remains in contact with the ground.
On the other hand, options A, C, and D in the given question are not correct in this context. Dolly towing involves using a dolly to lift the front wheels of the towed vehicle off the ground, while wheel-lift towing involves lifting only one pair of wheels off the ground. Off-road towing refers to towing a vehicle in off-road conditions.
