Final answer:
To turn left into a driveway, start by signaling left in advance, check mirrors and blind spots, ensure the way is clear, slow down, and then turn when it's safe.
Step-by-step explanation:
If you want to turn left into a driveway, the first thing that you need to do is signal your intention to turn left well in advance of the driveway. This involves checking your mirrors and your blind spot to ensure it's safe to make the turn, and then clearly communicating your intent to other road users by using your vehicle's left turn signal. Once you've ensured the way is clear and you've indicated your intention, you begin to slow down, position your vehicle correctly in the lane, and when safe, execute your turn into the driveway.
