The W-002L sign is a warning sign indicating that a side road will join the main road from the left. It serves to alert you to a potential traffic conflict point, giving you time to prepare for vehicles that might emerge.
When you see the W-002L sign, you should immediately reduce your speed and increase your scanning of the road ahead and to your left. Be prepared to yield to any traffic coming from the side road, as they may not see you or may be entering the road without yielding to you.
No, the 'Side Road - Left' sign itself does not automatically require you to stop. However, you must be prepared to stop if a vehicle emerges from the side road and you are not able to proceed safely without causing them to stop or swerve. Always prioritise yielding to traffic from the side road if necessary.
A common mistake is not slowing down sufficiently or failing to increase observation on the side road. Some learners might assume they have priority, which is incorrect. The theory test expects you to demonstrate hazard awareness and prepare to yield, not to proceed as if the side road wasn't there.
You should not overtake or change lanes when approaching an area where a side road joins from the left, especially if it could impede your view of the junction or the view of emerging traffic. Prioritise safety and be ready to react to potential traffic from the side road.
