1. A vehicle head-up display arrangement comprising:

  • a vehicle windshield and a projection unit arranged to selectively project light onto the vehicle windshield;

    a vehicle driver eye position estimation unit for estimating eye position of a vehicle driver;

    a detecting unit arranged to detect traffic signs in an environment external to a vehicle hosting the arrangement, and to detect locations of the traffic signs in relation to the vehicle; and

    a processing unit arranged to determine content of the traffic signs detected by the detecting unit;

    wherein the processing unit further is arranged to determine relevance of the content of the traffic signs detected by the detecting unit, and the projection unit is arranged to project light onto one or more areas of the windshield in line with the estimated eye position of the vehicle driver such that traffic signs detected in the environment external to the hosting vehicle determined to have content not relevant are at least partially covered by the projection unit on the windshield by blocking the not relevant content of the detected traffic signs from the estimated eye position of the vehicle driver without projecting an expanded view of an area from a field of vision of the driver.
