When driving on the road, always keep in mind the safety procedures that you need to do in order for you to stay out of harm's way. Your safety should be your primary concern as you won't only get to your destination as you can die on road too. Accidents do happen at the least expected time, but we can avoid it most of the time, if we are only to observe some traffic rules while driving. You don't want an accident to happen whenever you are since you are not sure if you are able to live through that. In this game, you won't be driving a car as you control the traffic system. In short, you can control if you want to avoid some accidents on the road. Anyway, you don't want an accident since that would mean the end of the game. You can't go to the next level.
