How To Properly Use Chevrons
Chevrons have a very specific use. They are used to indicate that a curve continues and can be placed closer together or farther apart depending on the tightness of the curve.
Many times chevrons are used incorrectly. People try to use chevrons to mark that a curve is coming or a turn and this is incorrect. They are used to mark the curve itself and that it is continuing on, especially if the curve is long.
Arrows are used to mark that a curve or series of curves is coming. A straight arrow is used to mark the start of the curve or a right or left turn.
