A car moving to transfer at the speed restrict determines how lots of time it takes to stop and what the preventing distance is.
A car traveling journeying 25 mph goes 36.7 feet in keeping with 2nd and is given three seconds to forestall. That means it is able to stop in only over 1 second at only 30 ft from the pinnacle bar.
