How should a driver execute a safe left turn (viraje a la izquierda) from a two-way street onto another two-way street?

1. Cut across the oncoming lane as early as possible
2. Approach the center line without crossing it, signal at least 30 m in advance, yield to oncoming traffic, and enter the intersecting street on the right-hand side of its axis
3. Turn from the extreme right-hand curb across all lanes
4. Sound the horn and accelerate through oncoming traffic
