Road Sign Information* (RSI)

The Road Sign Information function (RSI1) helps the driver to observe speed-related road signs and certain prohibition signs as the car passes them.

Examples of readable signs2.

RSI provides information about such things as current speed, when a motorway or road is starting/ending, when overtaking is prohibited or when the direction of travel is one-way.

If both a sign for motorway/road for motorised traffic and a sign showing the maximum permitted speed are passed, RSI decides to show the sign symbol for motorway/road for motorised traffic.


  • The Road Sign Information function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • Road Sign Information is not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
