In my country, the Ford F150 truck would be referred to as a car or a "half-truck", while a semi-truck is what would be referred to as a truck. That's a piece of cultural difference that will dirty your training.
It might be called a car or a pickup truck but never just a truck by someone here. While "pickup truck" is an American inherited phrase which has truck in it, they're considered trucks about as much as a catfish is considered a cat.
