Analysts seem divided on whether this is the start of a more flexible currency regime for China or an old-style devaluation. It appears to be a bit of both. China's economy has been struggling and a weaker currency would give it a boost, although most commentators say a steeper fall would be needed for a real impact.
The length of time depends on the severity of the offense. Most points (illegal turn, not making a complete stop, driving over the speed limit, etc.) and/or accidents will stay on your driver record for 39 months (3 years, 3 months). Points for more serious offenses, such as hit-and-run or a DUI, will stay on your record for 13 years.
How long will traffic ticket points stay on my record? State law does not permit the Secretary of State to prematurely remove points from a driving record, nor is it possible to have a conviction for a traffic offense set aside. As a consequence, the points for any traffic ticket conviction will remain on your record for two years from the date of the conviction. This is why it is so important to fight every single ticket you receive, rather than waiting until you get a ticket which will push you over the 12-point limit.
