						  through an opening in the traffic barrier.
Advisory speed
-The recommended speed
						  for vehicles operating on a section of highway based on the highway design,
						  operating characteristics and conditions. When posted, the speed is displayed
						  as a warning sign; that is, either a black-on-yellow or a black-on-orange
						  sign.
Angle parking
-Parking, other than
						  parallel parking, which is designed and designated so that the longitudinal
						  axis of the vehicle is not parallel with the edge of the roadway.
