The express delivery is one of the toughest business since you will be having a problem with your customer if you left out some cargoes on your way to the destination. If you fail to impress your customers, then your reputation is at stake here. There will be bad write ups about your business and that won't be good for your business. You could lose a lot here. That is why; it is important that you hire a driver that has pass psychology test so that you are assured that the cargoes are safe. You don't want a driver that are like kings of the road.
Wait till the cargoes are all loaded at the back of your truck. After that, you can drive as fast as you can till you reach the destination. Drive fast, but carefully as you don't' want those cargoes to be lost while you are on your way to the destination. The road ahead is tricky so it would be impossible not to lose cargoes, but you can minimize the lost by balancing your truck. Time is not restricted in this game, but you would get better score if you finish early. Don't bother with the lost cargoes as you can't do anything about it.
