When should you begin turning left from a two-lane street onto another two-lane street?

Turning left at an intersection requires careful timing and positioning to ensure safety and compliance with traffic regulations. The correct approach is to begin turning at the start of the intersection. This allows you to follow a smooth trajectory into the intersecting street while also being mindful of oncoming traffic and any pedestrians that may be crossing.

When you start your turn at the beginning of the intersection, it positions your vehicle appropriately within the lane, enabling you to complete the turn while still maintaining control and visibility. It is essential to signal your turn well in advance to alert other drivers and pedestrians.

Turning before reaching the intersection could lead to confusion about your intention and may jeopardize safety as you might not have a clear line of sight to gauge oncoming traffic. Turning after clearing the intersection could cause you to end up in the wrong lane or even create a hazard for other road users. Halfway through the intersection could lead to misaligned positioning with the road you're entering, which might also pose risks both for you and the vehicles around you. Thus, initiating the turn at the start of the intersection is the safest and most effective method.
