California DMV Permit Test (Class C)Rules of the Road and Right-of-WayEasy

You are driving on a two-lane road and wish to make a left turn at an upcoming intersection. There is a solid double yellow line separating your lane from oncoming traffic. What is the correct procedure for making this turn?

  1. AYou may only turn left across a solid double yellow line if you are making a U-turn.
  2. BYou must go to the next intersection where there is a break in the double yellow line to make your turn.
  3. CYou may turn left across a solid double yellow line if it is safe and there are no signs prohibiting it.
  4. DYou may turn left across a solid double yellow line if you are entering or leaving a driveway or private road.
Show answer & explanation

Correct answer: D. You may turn left across a solid double yellow line if you are entering or leaving a driveway or private road.

California Vehicle Code permits crossing a solid double yellow line to make a left turn only when entering or exiting a private road or driveway. All other left turns across solid double yellow lines are prohibited.

Why the other options are wrong

  • A. This is incorrect; U-turns have different rules and are not the only exception for crossing a double yellow line.
  • B. This is incorrect; you can turn across a double yellow line under specific conditions.
  • C. This is incorrect; safety alone does not permit crossing a solid double yellow line for a general left turn.

Solid Double Yellow Line (Left Turn Exception)

A solid double yellow line typically prohibits crossing. However, a specific exception allows drivers to cross it to make a left turn when entering or exiting a private road or driveway.

  • Double yellow lines separate traffic moving in opposite directions.
  • Solid double yellow lines generally mean no passing.
  • Left turns across solid double yellow lines are allowed only for driveways/private roads.

Memory trick: Double Yellow, Double Trouble, unless you're heading home or to a private bubble.
