The J29 sign, also known as 'Oncoming Traffic' or 'Two-way traffic', indicates that you will soon encounter vehicles travelling in the opposite direction. This is common after stretches of road that were previously one-way or divided.
Upon seeing the J29 sign, you must anticipate opposing traffic. This means you should adjust your driving behaviour: keep to the right side of the road, be extra cautious when overtaking, and be prepared to use your dipped headlights, especially in poor visibility or at night.
This sign is important because it signals a potential hazard – the risk of head-on collisions. For the theory exam, you need to demonstrate that you understand the implications of two-way traffic and know how to adjust your speed and lane position accordingly, particularly when overtaking.
While the J29 sign itself doesn't explicitly prohibit actions, it strongly implies that you should avoid behaviours that are risky in two-way traffic. This includes overtaking when there isn't clear sight of oncoming traffic and cutting blind corners where you might meet an opposing vehicle unexpectedly.
You'll usually encounter the J29 sign after a period where traffic was separated, such as at the end of a central reservation on a dual carriageway, or when exiting a one-way street that transitions back to two-way traffic. It serves as a heads-up to the change in road conditions.
