Road signs

Speed indicator signs

Speed indicator signs tend to be reserved for where speeds are known to be a particularly excessive problem.

Assessing the need for speed indicator signs

Current policy on speed indicator signs is only to consider further interventions where an exceptional case can be put forward.

There are a number of reasons for this:

  • the more widely the speed indicator signs are utilised the more diluted their overall impact is and the less effective their presence becomes (at all locations)
  • the impact on driver speeds is not always as effective as communities anticipate. This is particularly the case in the longer term and where drivers are predominantly repeat users of a route
  • the equipment does not have great longevity and can require regular maintenance/replacement. Our Street Lighting department, who maintain the equipment, are very much at capacity in terms of both staff resource and budget at the current levels of deployment

We have a responsibility to ensure consistency on the road network and must address sites based on established speeding issues.

Flashing Signs

The use of fixed flashing signs is reserved to locations in the vicinity of schools. 

Portable SIDS

We operate two battery powered Speed Indicator Devices (SIDs) which are rotated between 18 sites. These devices will be in place for approximately one week before requiring a recharge and are then moved to another location. Communities can request that they are included in the rotation for these signs, assuming a speeding problem is identified by a traffic speed survey or through Police Scotland.

To be considered for inclusion in the SID rotation, submit a request through your Community Council or local Councillor:
