OFFSET

SIDE OF ROAD

MEDIAN is used when the sign is in the center of the median

On undivided roadways (including ramps and crossovers) RIGHT and LEFT are based on the PR direction RIGHT is on the right and LEFT is on the left while travelling in the positive direction of the PR. When travelling in the negative

PR direction LEFT will be on your right and RIGHT will be on your left

(too far over to be LEFT for either direction). If the median is narrow, for instance, where a Keep Right symbol would be used, then use MEDIAN.

Offset is measured from the right side of thru travelled way in direction of travel. Postive is to the right and negative is to the left regardless of PR direction

On divided roadways the RIGHT and LEFT are determined by the direction of travel.

RIGHT is always on the right and LEFT is always on the left.
