Warning of Slippery Road
The sign indicates that the road may be slippery. It is used to warn of slippery conditions due to snow or ice only if there are specific reasons.
When You See This Sign
When you see the sign you should immediately reduce speed and drive more cautiously. Increase following distance, avoid sudden maneuvers and select gears so that you have good control of the vehicle.
Rules & Regulations
- The sign is a warning sign (A10) indicating that the road surface may be slippery and requires you to exercise particular caution.
- The sign is placed before the stretch where the risk of reduced grip exists and may be supplemented with an additional plate indicating the cause or the length of the stretch.
- The warning sign itself is not a prohibition or a speed limit, but you are expected to adjust speed and driving style to the conditions the sign warns about.
- The sign is generally used for slippery roads; only in special cases is it used to specifically warn of slipperiness caused by snow or ice.
Tips for Drivers
- Reduce speed well in advance and brake gently to avoid wheel lock and skidding.
- Increase the distance to the vehicle ahead so you have more time to react if grip suddenly deteriorates.
- Avoid sharp steering maneuvers and accelerate gently to minimize the risk of wheel spin.
- Prefer a lower gear when needed for better engine braking and control, especially downhill or when the road feels slippery.
Common Mistakes
- Believing the sign always means snow or ice; it can warn of many types of slipperiness (e.g., oil, gravel, wet leaves).
- Misinterpreting the sign as a prohibition or as meaning you must stop; it is a warning that requires adjusted driving rather than stopping.
- Braking suddenly or steering sharply when the road becomes slippery instead of making controlled, gentle maneuvers.

Exam Tip
On the theory test they may ask about the difference between a warning sign showing general slipperiness and a supplementary plate indicating 'snow/ice' — remember that A10 normally warns of all types of slippery road and is only in special cases used for snow or ice.
Did You Know?
The symbol for slippery road is internationally recognizable and in Sweden it is designated A10 in the traffic sign register.
Frequently Asked Questions
Does the sign only apply during winter?
No, the sign warns that the road may be slippery regardless of season. Snow and ice are only one of several possible causes, and the sign can be used when other conditions give poor grip.
Does the sign mean I must have winter tires?
No, the sign itself does not impose any requirement on tire type. Tire regulations (e.g., requirement for winter tires in winter conditions) are regulated separately and you must always adapt your tire choice to the prevailing conditions.
Can the sign be supplemented with an additional plate?
Yes, the warning sign is often complemented by a supplementary plate indicating, for example, the length of the stretch or the cause (e.g., 'ice/snow'). The supplementary plate clarifies what the warning refers to or over which distance it applies.
What happens if I ignore the sign and cause an accident?
Ignoring a warning sign can affect your duty and liability in an accident; you are always expected to adapt your driving according to the warning. Neglecting to do so can lead to being held responsible for resulting damage or facing traffic law consequences.
