Difficulty: HardSpeed Limits and Speed Regulation

A driver is operating a vehicle on a city street with a posted maximum speed limit of 35 mph. As the driver approaches an uncontrolled intersection without stop signs or signals, tall buildings completely block the driver's view of potential cross-traffic for the last 100 feet of the approach. Under standard traffic laws and speed regulations, what is the maximum speed the driver may legally travel during the final 100 feet before entering this blind intersection?

  1. 15 mph, because this is the statutory speed limit for a blind intersection when cross-traffic sightlines are obstructed.Answer
  2. B
    35 mph, because drivers may legally maintain the posted speed limit as long as no cross-traffic is currently visible.
  3. C
    25 mph, because all uncontrolled urban and residential intersections carry a default 25 mph speed restriction.
  4. D
    20 mph, provided the driver taps the horn to alert approaching cross-traffic before entering.

Answer

The maximum legal speed when approaching and entering a blind uncontrolled intersection is 15 mph.
The statutory speed limit for a blind intersection—defined as an uncontrolled intersection where you cannot see for 100 feet in either direction during the last 100 feet of approach—is 15 mph. This rule ensures the driver has sufficient stopping distance if cross-traffic suddenly appears.

Step-by-Step Solution

1
Identify the type of intersection and sightline conditions described.
The scenario describes an uncontrolled intersection where buildings block the view of cross-traffic for the final 100 feet of the approach, defining it as a blind intersection.
Speed regulations establish specific prima facie / statutory limits based on specific hazard conditions.
2
Apply statutory speed limit regulations for blind intersections.
Standard traffic regulations mandate a maximum speed limit of 15 mph for blind intersections when cross-traffic visibility is restricted within 100 feet.
Operating at higher speeds prevents drivers from stopping safely if another vehicle enters the intersection unexpectedly.
