Overlooks:
In placing guardrail or parapets at overlooks, let the setbacks
from the edge of pavement be ample so that motorists can park safely
or close enough to the pavement edge to prevent their parking...we
can't have both! And don't locate parking areas on one side of the
pavement where cars must drive across the opposing land unless
there is ample sight distance in both directions! I believe it's
safer to provide a deceleration lane and a 90° throat than to bring
cars into a long acute angle approach of insufficient length to
slow down.
