A two-lane minor road intersects a two-lane major road at 90° forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 125 ft from the centerline of the outside lane of the major road and 35 ft from the centerline of the nearest lane of the minor road. Determine the maximum speed that can be allowed on the minor road if the speed limit on the major road is 45 mi/h.

Qu. A two-lane minor road with a +5% approach grade intersects with a four-lane undivided road. Determine the minimum intersection sight distance on the major road required for a stopped single-unit truck to depart from the minor road (in the upgrade direction) and turn right onto the major road. The design speed is 30 km/h on the minor road and 50 km/h on the major road.
