which part of the uk do traffic officers operate
Highways England Traffic Officer Service In April 2004, Highways Agency Traffic Officers (HATOs) began working alongside police on motorways in the West Midlands.[1] The roll-out of traffic officers was completed on 18 July 2006 and they now cover all of the motorway network within England, i.e. that which is owned or managed by Highways England[clarification needed], and some of the all-purpose trunk road (APTR) network. The introduction of the officers was aimed to reduce the 25% of delays caused by collisions by around 5%.[1]
Turn on red In the United Kingdom, which drives on the left, left turn on red is prohibited, but at some junctions there is a separate left arrow-shaped green "filter" light which, when lit, allows left-hand turns but conflicting traffic will always have a red signal.[16] Other non conflicting traffic movements may have their own left or right arrow-shaped green light. Sometimes there are specific lanes without signals for turning left, separated from the through traffic signalled traffic by traffic islands, but give way signs are installed.
