Texas DMV Written Driving Practice Test

Passing other vehicles can be a dangerous maneuver and requires extra caution. Option A, sounding your horn, is incorrect because using your horn should only be done to provide a warning or alert to other drivers. It should not be used as a go signal to pass. Option C is incorrect because there is no need to do the same action twice for safety purposes. Option D, accelerating, may seem necessary but it is important to first check your mirrors and blind spots to ensure there are no other vehicles in the way before attempting to pass. This allows you to have a clear view of your surroundings and make a safe decision to pass. Therefore, option B, checking your mirrors and blind spots, is the best answer as it ensures you have a clear understanding of your surroundings before passing.
