Which of the following is important to do when preparing for a left turn?

When preparing for a left turn, signaling well in advance is essential. This action informs other drivers and pedestrians of your intent to turn, enhancing safety on the road. Proper signaling allows others to adjust their actions accordingly; for instance, it lets vehicles behind you know that you are slowing down and will be changing direction. It is recommended to signal at least 100 feet before making the turn, providing ample notice to surrounding road users.

It's also important to note that simply looking for pedestrians is not sufficient, as many factors must be considered when turning, such as oncoming traffic and road signs. Accelerating through the turn is generally unsafe, as it can lead to losing control or not being able to react to obstacles or pedestrians. Lastly, making a left turn from the right lane is incorrect as it would violate traffic rules and could lead to hazards.
