Almost all driver's manuals or handbooks have information about the shapes and colors of traffic signs. It isn't always obvious why you need to learn this. But being able to identify signs from a distance by just the shape or color coding, can help you a lot. You also need it for your written driving test.
If you are under 21 years, it is important that you understand the zero tolerance law. Even a small amount of alcohol can easily put you at risk. It is also important to know that a conviction based on blood alcohol content is more or less automatic. No other proof is needed. And remember, any traces of alcohol in your blood may result in a conviction.
