What is the speed limit at a blind intersection?

• A. 25 mph
• B. 15 mph
• C. 20 mph
• D. 10 mph

Answer: (B)

When you approach a blind intersection you can’t see cross traffic in time to react, so you must slow down enough to stop if something unexpectedly appears. The practical safety speed at this point is about 15 mph or slower, which gives you the necessary time to identify any vehicles, pedestrians, or cyclists that might be in or approaching the intersection and to brake safely. Going faster reduces your stopping distance and increases the chance of a collision if a vehicle or pedestrian suddenly comes into view. The other speeds are less appropriate because they don’t leave as much time for perception, decision, and braking given the limited visibility. Slowing to about 15 mph keeps you moving cautiously while still allowing for a reasonable flow of traffic.
