Don't lead out!
When making a left turn don't lead out into the intersection. Stay behind the solid white line until the intersection is clear for you to make your turn. By staying behind the line you gain greater visibility down the road to know when it's clear for you to make your turn. If you lead out then it blocks the vision of the person across from you who is turning left. Also you never know when emergency vehicles will come through an intersection and by not leading out, you're keeping the intersection clear and keeping you safe from any speeding vehicle.
