The Federal Motor Carrier Safety Administration is getting closer to proposing a rule that would create a national clearinghouse for drug and alcohol test results.

The proposal, long sought by trucking interests, has been in the works since 2009. Tuesday the Office of Management and Budget reported that the proposal is in line for White House vetting, a process that could take several months.

The industry will have a chance to comment on the proposal when it is published. Last year’s highway law gave the agency until October 2014 to post a final rule.

Details are not available, but in general the proposal will call for carriers to query the clearinghouse when screening applicants for driving job, and annually after they are hired. The proposal is likely to permit third-party services to do the searches.
