Difficulty: MediumSpeed Limits and Speed Regulation

A driver approaches an uncontrolled intersection where tall buildings block line-of-sight vision of cross traffic within 100 feet in both directions. Although the approaching roadway has a posted speed limit of 35 mph, what is the maximum prima facie speed limit when traversing this blind intersection?

  1. 15 mphAnswer
  2. B
    25 mph
  3. C
    35 mph
  4. D
    5 mph

Answer

15 mph
Under traffic speed regulations, the statutory prima facie speed limit is 15 mph for any blind intersection where a driver cannot see cross traffic for at least 100 feet in either direction during the last 100 feet of approach.

Step-by-Step Solution

1
Identify the road condition and visibility constraints in the scenario.
The vehicle is approaching an uncontrolled blind intersection with sightlines restricted to less than 100 feet.
Traffic law establishes specific reduced prima facie speed limits for blind intersections to prevent broadside collisions.
2
Apply the statutory speed regulation for blind intersections.
The legal speed limit drops to 15 mph while traversing the intersection.
A speed of 15 mph ensures the driver has sufficient time to yield to any unseen vehicle entering from the cross street.
