Labrador Retriever Puppy keeps getting car sick?

Ok, I don't know how often little puppies get car sick but, my little lab keeps getting car sick. He can stand being in the car for about.... 5 minutes... he threw up in the car twice through a one hour drive. First, he starts looking all nervous or something... or, unsettled and then he starts whining and in the one hour drive he started hyperventilating and then he threw up eventually. So, any help?
