DOT Clearing House 

According to the DOT employee handbook on alcohol and drug testing procedures, the department’s goal is to “employ operators who are 100 percent drug- and alcohol-free. The Clearinghouse enables employers to identify drivers who commit a drug and alcohol program violation while working for one employer, but who fail to subsequently inform another employer. 

IF YOUR DRIVER IS TESTED POSITIVE THEN THEY WILL NEED TO GO THROUGH DOT CLEARING HOUSE AND GO TO A SAP IN ORDER TO GET CLEARED. With our services we will help with any positive drug test and new hire queries and annual queries reports for your company.
