can you turn left on a red light in england
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.
Automotive lighting The colour of light emitted by vehicle lights is largely standardised by longstanding convention. It was first codified in the 1949 Vienna Convention on Road Traffic and later specified in the 1968 United Nations Convention on Road Traffic.[5][6] With some regional exceptions, lamps facing rearward must emit red light, lamps facing sideward and all turn signals must emit amber light, while lamps facing frontward must emit white or selective yellow light. No other colours are permitted except on emergency vehicles.
