Two cities have found a relatively novel way to reduce high-speed crashes by rewarding law-abiding drivers rather than just punishing the lead-footed ones.

Road safety activists and some states are pushing to depart from a longstanding rule that sets speed limits in the United States based largely on how fast drivers actually travel.

Removing lanes to slow down speeding drivers is a long-embraced strategy for improving safety on city streets.

Almost every major city in the United States generally allows drivers to turn right at red lights, but that could be changing.
