Frequently Ask Questions

What is the FMCSA Drug & Alcohol Clearinghouse?

The Clearinghouse is a federal database maintained by FMCSA that contains records of CDL drivers’ drug and alcohol program violations. Employers must query the Clearinghouse before hiring a CDL driver and conduct annual queries for all current drivers.

Do owner-operators need to join a consortium?

Yes. Owner-operators who are their own employer cannot run a solo random testing program — a single person cannot be randomly selected. You must join a consortium like EZDOT to meet the random testing requirement.

What is the current FMCSA random testing rate?

FMCSA currently requires that at least 50% of your covered drivers be tested for drugs annually, and at least 10% be tested for alcohol. EZDOT tracks your selection rate and ensures you meet these minimums.

When must I test after an accident?

For alcohol testing, you have 8 hours after the accident. For drug testing, you have 32 hours. If you cannot test within these windows, document why. EZDOT can help you locate the nearest collection site 24/7.

What happens to a driver who tests positive?

The driver must be immediately removed from safety-sensitive functions. The violation is reported to the FMCSA Clearinghouse. The driver must complete a SAP evaluation and return-to-duty process before resuming CDL duties.

How does APCA handle the annual MIS report?

EZDOT provides you with the data you need to complete your annual Management Information System (MIS) report, which is required by FMCSA. We keep all your testing records organized so reporting is straightforward.
