Florida Learner's Permit Practice Test

When driving on a highway with multiple lanes, it is important to always signal your intention before changing lanes. Option A is incorrect because making sudden bursts of speed when passing can be dangerous and could potentially cause an accident. Option B is also incorrect because there may be situations where it is necessary to change lanes, such as to exit the highway. Option D is also incorrect because straddling lanes and blocking traffic is not only against traffic laws, but also puts the driver and other vehicles at risk. Therefore, option C is the safest and most appropriate choice when driving on a highway with multiple lanes.
