Question: A 'Two-Way Left Turn Only' centre lane is bordered by:

Answer options:

  • Two solid white lines ✅ A solid yellow line on each side with a broken yellow line inside
  • Diamond symbols
  • Bike lane markings

Correct answer: A solid yellow line on each side with a broken yellow line inside

Explanation: Under Ontario's Highway Traffic Act, a two-way left-turn lane is bordered by a solid yellow line on the outside with a broken yellow line on the inside. This specific marking alerts drivers from both directions that they may enter the central lane only to prepare for a left turn. In contrast, two solid white lines prevent lane changes between traffic moving in the same direction, while diamond symbols and bike lane markings designate reserved or cyclist-only lanes. Understanding pavement markings is a key concept for Ontario road safety. Expect questions about lane markings on the G1 exam to ensure you can identify appropriate lanes for turns and maneuvers.
