Is it a big deal to cross the yellow line when turning left?

[BradyLynn]

It is considered a violation, mainly depending on which yellow line was crossed. If it's the yellow line at the exit of the turn, generally no penalty will be imposed. However, if it's the double yellow line for a left turn, a fine and three demerit points will be issued. Below is the relevant information: 1. Function: Central dividers and double yellow lines are commonly found on main and secondary roads in urban areas, serving as primary facilities to separate opposing lanes. However, they differ in terms of roadside strips, safety zones, and lateral clearances. 2. Overview: Double yellow lines are common road traffic markings composed of two parallel solid yellow lines. They are typically placed in the middle of roads without central barriers, dividing opposite traffic directions and separating vehicles traveling in different directions with ground markings. Under normal circumstances, civilian vehicles are not allowed to cross these lines. Some roads with simple small guardrails may also have double yellow lines. Vehicles can only turn or make a U-turn at the break in the double yellow line when other traffic signs permit.
