The closest thing to a clearing house would be the DMV's which act to collect and distribute information about traffic offenses to a driver's home state. Certain offenses, such as DUI's (whether in a commerical vehicle or not) will result in immediate revokation of a CDL. Other offenses, like improper passing are labled as major, and are limited to three in a two year period before the license is revoked. The biggest problem with this system is the fact that each state's DMV must cooperate with other states to relay the information. Offenses do not always \"match\" from state to state, sometimes resulting in serious issues on both sides of the coin. A driver who commited a major offense in one state may find that when it was reported to the home state, it was converted into a less serious offense. Sometimes, offenses may not ever make it back to the home state at all. On the flip side, a drive who commited a minor violation may find it translated into a more serious offense by his home state, resulting in difficulty getting or keeping a job, or increased insurance rates. The new CDL was supposed to fix these issues but hasn't. New legislation has been proposed to improve the system. The FMCSA (Fedral Motor Carrier Administration) and DOT could also fall under the category of \"clearing house\" as they work to ensure that drivers and companies follow the Hours of Service Regulations as well as other rules. The FMCSA maintains records of saftey violations and accidents for each carrier. This system, known as SaferStat, combines the information into a report that is accesable to the general public at www.fmcsa.dot.gov The information on these reports can also be misleading, because percentages are used to report accidents and violations by each carrier. Since some carriers encompass thousands of trucks and some have only one or two, a carrier with hundreds of accidents and violations may be assigned a safer score then a one truck carrier that was involved in a minor fender bender or had a minor violation. The DOT has the authority to audit any trucking operation, and to inspect any driver's equipment or logs for violations. If any are found, the DOT may also suspend the operating authority of a carrier or put a vehicle or driver out of service. The biggest problem withing the commercial trucking industry today is not getting unsafe drivers off the road, however. It is keeping them from getting there in the first place. The requirements for obtaining CDL are not nearly stringent enough, and many training schools are allowed to test their own students and issue CDLs. This \"third party testing\" puts the responsibility of ensuring that a new driver is competent to handle an 80,000 lb vehicle into the hands of entities whose primary goal is to get drivers in seats. Recently Missouri had to recall thousands of improperly issued licenses after it was discovered that a training school had used the same home address for several thousand applicants. The investigation uncovered that the school was selling the licenses without any actual testing. Most of these drivers are still on the road, however, as they are being called in at the rate of about 60 oer month for retesting. The licenses will be treated as valid until they are called.

Why do you ask so many questions that you know the answers to? Do they have a clearinghouse on bad car drivers? Because statistics show that truckers are far more safer drivers than car drivers. So if there is a clearinghouse for ANY bad drivers, the police will be targeting cars, AS THE DO ALREADY NOW by riding in the passenger seat with truckers, and radio to fellow troopers of violations, then the violator is pulled, and ticketed. Tickets issued were for tailgating, failure to use signals during lane change, speeding, failure to leave enough space between vehicle passed..

I guess just like driving anywhere else. too many accidents and you are gone.
