A unique call that a light-duty operator may be asked to take is transporting two casualties at the same time to the same location. For light-duty operations, this can be tackled by using a car carrier. While the bed of a carrier can not fit two vehicles, most carriers also have a wheel lift that can be used to tow vehicles.
LOADING THE VEHICLES
When loading two vehicles on a carrier, the most important thing to remember is that the heavier of the two vehicles should be loaded on the bed of the truck. The casualty should be treated no differently than any other vehicle loaded on the bed of the truck.
After the heavier vehicle has been secured to the carrier with at least four points of securement, the second vehicle can then be hooked up using the wheel lift at the back of the truck. This should also be hooked up the same way you would normally hook up a vehicle. When driving with two vehicles on a carrier, remember than the vehicle will be longer than you are typically used to. In addition, both stopping power and turning radius of the carrier will be affected. Be sure to practice this technique at the yard or in a controlled environment prior to attempting in the field.
