Florida Learner's Permit Practice Test

Changing lanes requires multiple steps to ensure safety. Option A, increasing speed, is not correct because it can actually be dangerous. Speeding up while changing lanes can cause you to lose control of your vehicle and increase the risk of accidents. Option B, signaling your intention, is also an important step to notify other drivers of your intended action. However, it is not the only thing you should do. Finally, option C, checking your blind spot, is also crucial. Your blind spot is the area around your vehicle that you cannot see in the mirrors. It is important to check this area before changing lanes to make sure there are no cars or obstacles that may cause an accident. Therefore, the correct answer is D, which includes all of the above steps for safe lane changing.
