The A1 sign's main purpose is to warn drivers that a sharp or hazardous bend is approaching. It helps you anticipate the need to steer and adjust your speed accordingly, promoting safer driving by giving you advance notice of a change in direction.
When you see the A1 sign, you should immediately start to slow down before you reach the curve. Maintain a safe position in your lane, avoid sudden braking or steering adjustments within the curve, and be extra cautious if visibility is poor or the road surface is slippery.
No, the A1 'Dangerous Curve' sign does not set a specific speed limit. It is a warning sign indicating a hazard. You must determine a safe speed based on the sharpness of the bend, road conditions (like rain or ice), traffic, and your visibility. Always be prepared to drive slower than the general speed limit if necessary.
A common mistake is failing to slow down early enough before the curve, leading to a situation where you have to brake sharply while turning, which can cause skidding. Another trap is misinterpreting the arrow; it shows the direction of the first main bend, but there could be subsequent bends that are also sharp. Always be prepared for what comes after the initial curve.
The arrow on the A1 sign illustrates the direction of the first and usually the most severe curve ahead. If the arrow curves to the left, a left bend is approaching. If it curves to the right, a right bend is coming. This helps you prepare your steering and positioning.
In winter conditions like snow or ice, the risk associated with a dangerous curve is significantly higher. When you see the A1 sign, you must reduce your speed even more drastically than in dry conditions. The road surface can be very slippery, making it easier to lose control if you enter the curve too fast or brake/steer abruptly.
