ARROWS AND SYMBOLS

The design standards for California show that wrong-way

arrows (one in each direction) are used at locations near
intersections and at a maximum of one-mile spacing where
motorists could perceive that they are on a one-way roadway 150

when, actually, they are on a two-lane, two-way highway.

The following are some typical situations:

The design standards for Georgia show that a different
spacing pattern is specified for lane-use arrows and ONLY

ramps. MISCELLANEOUS TREATMENTS
