1. Slippery road

A slippery road has reduced tyre grip and can make steering, braking and acceleration less effective. Roads may become slippery because of rain, ice, snow, mud, oil, loose material or other substances on the surface. Drivers should reduce speed, increase their following distance and avoid sudden steering, braking or acceleration. Extra caution is needed in bends, on bridges and wherever the road surface changes unexpectedly.

What can make roads slippery in Indonesia?

Water, ice, mud, oil or other surface contamination can reduce grip where present. Conditions may change along the road, and a surface that looks clear can still be slippery. Reduce speed for the actual grip and visibility and use smooth steering, braking and acceleration.

How should you drive on a slippery road in Indonesia?

Reduce speed early, increase the gap to the vehicle ahead and use smooth steering, braking and acceleration. Do not rely on the posted maximum as a safe target when grip is poor.

Does a slippery-road warning sign in Indonesia automatically impose a lower number?

The warning sign highlights a reduced-grip risk; it normally does not itself prescribe a new numerical speed limit. A separate speed-limit sign, temporary restriction or local condition may still apply. Travel below the legal maximum when necessary for safety.
