What should a driver do before making a left turn from a two-way street to another two-way street?

Before making a left turn from a two-way street to another two-way street, signaling and checking mirrors is essential for ensuring safety and smooth traffic flow. The act of signaling informs other drivers and pedestrians of your intention to turn, allowing them to prepare for your maneuver. Checking your mirrors helps you gain awareness of any vehicles or pedestrians that might be in your blind spots, ensuring that the coast is clear before you execute the turn.

While stopping before the corner may be necessary in certain situations, it is not a general rule for every turn and can depend on traffic conditions. Speeding up to turn quickly is not a safe practice as it can lead to accidents, especially if oncoming traffic is present. While looking for oncoming traffic is important, it is encompassed within the broader practice of checking mirrors and being aware of the surrounding environment, which is part of a good driving routine. Thus, signaling and checking mirrors stands out as the most comprehensive and safest approach for executing a turn.
