Final answer:
The correct speed at an uncontrolled intersection with limited visibility is not provided, as it varies based on local laws and conditions. A safe approach is to go slow enough to stop if necessary, often 15 to 25 MPH, adjusting as needed.
Step-by-step explanation:
The question does not provide enough contextual information to unequivocally state the correct speed limit for an uncontrolled intersection where cross traffic is not visible until you are about to enter.
This is because speed limits can vary by location and are set by local laws or ordinances. However, traffic safety guidance suggests that at intersections with limited visibility, drivers should approach at a speed that allows them to stop if necessary. This is often lower than the posted speed limit for the area.
In general, residential area speed limits can range from 15 to 25 miles per hour (MPH), but you must always refer to local traffic laws or road signs for specific speed limits. Moreover, local conditions such as visibility, traffic density, and other factors can require drivers to adjust their speed accordingly for safety.
If a speed is not posted, and no guidance is given, a safe, prudent speed in residential areas is often 25 MPH, but in intersections with poor visibility, slowing down further to 15 MPH or the speed necessary to ensure safety would be advisable. Always err on the side of caution where safety is a concern.
