I am a bit puzzled as to the standard direction for creating italic 2 sided door lettering like 'Sheriff or Police' Some vehicles I have seen have the letters facing/leaning towards the rear when viewed from the left side of the vehicle and facing/leaning forward when viewing the right side of the same vehicle. Other police vehicles I have seen have both sides of the vehicle with the same rear facing italic lettering. Hope I have explained it to everyone's understanding. Just want to know which way is correct. Sample pictures attached of two different vehicles with forward facing letters on one side and rear facing on the other.
