The T-18a sign indicates an unexpected change in road direction, specifically a sharp turn to the right followed by a sharp turn to the left. It's a warning sign designed to alert drivers to hazardous or unusual road layouts they might encounter, often due to roadworks.
Upon seeing the T-18a sign, you must reduce your speed significantly and be prepared to steer sharply first right, then left. Look for temporary road markings, cones, or barriers that will guide you through the altered path. It's crucial to anticipate the changes in direction and maintain control of your vehicle.
While the sign itself doesn't list prohibitions, common sense and the nature of the warning dictate certain actions are forbidden. You must not drive over any temporary barriers or cones marking the detour, nor should you assume the diverted path is wider than the original road. Always adapt your speed to the sharp angles shown and implied by the sign.
A common exam trap is not understanding the sequence of turns indicated by the diagram (right then left). Learners might also fail to reduce speed sufficiently, assuming the detour is straightforward. Remember that this sign implies a need for careful control and awareness of the vehicle's path.
The note about yellow temporary lines means that when you see the T-18a sign, you should look for yellow road markings or delineators. These markings are specifically placed to guide you through the unexpected right-then-left path, especially in temporary traffic management schemes or roadworks.

Master Roadworks: Prioritize Temporary Markings for a Safer Drive and Exam Pass.
This sign is a variation of the priority warning, specifically highlighting a junction on the right. Drivers on the side road are required to yield (usually marked by an A-7 or B-20 sign). It is used to ensure the driver on the main road is aware of potential traffic merging or crossing from the right, which is often a 'blind spot' or a common source of side-impact collisions.
The T-18 plate indicates a 'S-curve' that might not be obvious from the road's general layout. This is often used where a road has been redirected due to bridge repairs, new construction, or a permanent bypass. Because the change is 'unexpected', it can catch drivers off guard, potentially leading to them running off the road. The diagram shows the exact shape of the maneuver you need to perform.
