What does the W-013 'Side Road on Dual Carriageway' sign mean?

The W-013 sign warns you that a side road is about to join the dual carriageway you are travelling on.

Upon seeing the W-013 sign, you must prepare for traffic emerging from the side road. The primary actions are to reduce your speed early, increase your scanning of the road ahead and to your sides, and be ready to adjust your position or stop if necessary to allow traffic from the side road to join safely.

What are common mistakes learners make with the 'Side Road on Dual Carriageway' sign?

A common trap is assuming that because it's a dual carriageway, you have priority. However, this sign specifically warns of a side road joining, so you must be vigilant for vehicles exiting that road. Another mistake is not reducing speed sufficiently or too late, leaving no time to react to emerging traffic.

Does the W-013 sign mean I must stop?

Not necessarily. The sign is a warning to be prepared. You must be ready to stop or yield if traffic from the side road is emerging or indicates an intention to join the dual carriageway. Your reaction depends entirely on the actual traffic conditions present when you approach the junction.

Why is it important that there's 'No Central Reserve Break' mentioned?

The 'No Central Reserve Break' detail is critical. It means traffic from the side road is merging onto your carriageway, unlike a junction on the opposite carriageway which might have a central reserve break. This requires you to be particularly aware of vehicles directly entering your lane of travel.
