What feature is common to one-way streets?

One-way streets are designed to allow traffic to flow in a single direction, which leads to several common features shared by these roadways. One prominent aspect is limited parking availability. Since vehicles can only be parked on one side of the street, this often results in fewer legal parking spots compared to two-way streets, where parking can occur on both sides.

Directional signage is also a key feature of one-way streets. These streets must have clear signage indicating the allowed direction of travel to prevent confusion for drivers. Such signage is crucial for maintaining safety and preventing accidents that could occur from vehicles going against the traffic flow.

In terms of speed limits, while one-way streets may have speed limits that vary, there is no automatic increase in speed limits solely because the street is one-way. Speed limits are generally determined by various factors, including road conditions and surrounding neighborhoods, rather than the direction of traffic.

Therefore, the option stating that all of these answers are correct encompasses the features commonly found on one-way streets. These streets indeed often exhibit limited parking availability and require directional signage to guide drivers safely, making the comprehensive understanding of these aspects crucial for navigating such roadways correctly.
