Vehicle activated signs



The safety benefits of vehicle activated signs (VAS) are proven but these can be lost through proliferation which lessens their impact and can lead to drivers disregarding those signs which have been installed at sites with significant crash histories. Vehicle activated signs are only provided in the following circumstances:

  • Where there is an ongoing history of crashes involving personal injury and all other practicable remedial measures, such as permanent signing, have already been implemented 
  • Where we have identified a speed management issue and are implementing the necessary measures to ensure drivers comply with the speed limit, particularly where we are proposing to lower the current limit
