In your job as a truck driver, you need to make sure that the cargoes are delivered at the right time and the right amount. It means that you need to get there in time without losing much of the cargoes. If you can't do that, then you can say good bye to your job. That is why; you got hired because of your experience because the management knows that they can rely on you. If you can't do your job well, then the whole operation would be paralyzed and you can say goodbye to your job. And your family would not want you to lose your job since that is where most of the family income are coming from. Your wife has a job, but the money he makes are not as much compared to that of your job. The idea here is to deliver the cargo as fast as you can to the destination. Drive as fast, but with safety in mind because that would make things safer for you. Aside from delivering the cargoes, you also need to consider your safety since you might incur an accident while you are at the road. You need to get there on time without compromising your safety.
