Think you know your Rules of the Road? Take our USCG Rules of the Road practice test and find out!
Passing your USCG licensing exam can be extremely hard, as you may have heard from friends who have already been through it.
The problem is that the USCG has a huge database of questions, and many of them test very obscure facts or are structured as trick questions.
What makes matters worse: you can only get 3 questions wrong in the Rules of the Road section of the exam before you fail. So you had better know these questions by heart!
Luckily, we have collected the exact same bank of questions and built a proven system to help you study and pass. We have helped over 15,000 mariners prepare for their Coast Guard Rules of the Road test so far, and we can help you too.
There are several ways to study these USCG Rules of the Road exam questions.
First, you can study in “answer” mode, which lets you browse the questions while instantly seeing the correct answer. We actually do not recommend this approach.
Much better is “normal” mode: you are presented with the question and its multiple-choice answers, you select your answer, and you instantly see whether you are correct. If you are wrong, the system clearly shows you the correct choice.
Take the online Rules of the Road quiz right now to see how it works.
Once you have tested yourself against literally hundreds of questions and feel ready, go ahead and generate a formal Coast Guard Rules of the Road practice test. It simulates the real exam: you answer all the questions and only see your results at the end.
