Driver Background Check Overview for CDL Hiring
CDL driver hiring involves several types of background verification: MVR (motor vehicle record), Clearinghouse query, PSP (Pre-Employment Screening Program), and previous employer safety history inquiries. This page explains each and when it is required vs. optional.
Motor Vehicle Record (MVR) — required
An initial MVR from each state where the driver was licensed in the past 3 years is a federal requirement under 49 CFR 391.23. It shows the driver's licensing history, violations, accidents, and CDL endorsements/restrictions in that state.
FMCSA Clearinghouse query — required
A full pre-employment Clearinghouse query is required before a CDL driver operates a CMV. It reveals drug and alcohol violations in the FMCSA database. Required since January 6, 2020.
PSP (Pre-Employment Screening Program) — optional but common
The FMCSA PSP report shows crash and inspection history from FMCSA's Motor Carrier Management Information System (MCMIS). PSP is optional — it is not required by regulation, but many carriers use it as part of their hiring screening. Drivers must consent to a PSP query.
Previous employer safety history inquiries — required
Written inquiries to previous DOT-regulated employers covering the past 3 years are required under 49 CFR 391.23. These are separate from MVR checks and cover safety performance information that may not appear on an MVR.
What each check covers — and what it misses
Each tool covers different data. The MVR shows state-recorded violations and license actions, but only what the state has posted — which can lag by weeks or months. The Clearinghouse covers federal drug and alcohol violations recorded since January 6, 2020. PSP shows federal crash and inspection history for the past 5 and 3 years, respectively, but is voluntary and costs a fee per query. Previous employer inquiries surface safety performance information from prior DOT-regulated jobs — things that may not appear on any public record. A carrier that only runs one of these tools has an incomplete picture.
PSP in more detail — what makes it useful
A PSP report can show crashes that were not prosecuted in court and inspection violations that never made it onto the state MVR. A driver who was involved in three crashes in two years might have a clean MVR if they were not ticketed in those incidents. PSP captures the crash regardless. For carriers where safety history matters — hazmat, passenger, dedicated fleets — PSP adds meaningful pre-employment data. The driver must consent to the query through FMCSA's PSP Online portal before the carrier can access it.
Documenting all checks — what goes in the DQ file
The initial MVR, the Clearinghouse query result, any PSP report obtained, previous employer inquiry letters and responses, and the pre-employment drug test result all belong in the driver's DQ file. Keep them organized from day one. FMCSA compliance reviewers will ask to see the file for a sample of drivers, including recently hired ones, and they will look for evidence that each required check was conducted and documented before the driver's first dispatch.
Frequently Asked Questions
Is PSP required or optional?
PSP is voluntary — no regulation requires carriers to run it. However, many carriers use it as part of thorough pre-employment screening because it surfaces federal crash and inspection data that MVR and Clearinghouse do not show.
What if a driver refuses to consent to a PSP query?
Drivers can decline PSP consent. Carriers may choose to decline to hire a driver who refuses, or they may proceed without the PSP data. The carrier's hiring policy determines how PSP refusals are handled.
How far back does PSP go?
PSP reports contain FMCSA crash data for the past 5 years and roadside inspection data for the past 3 years. State MVR records go back further depending on the state — typically 3 to 10 years for serious violations — and the two records cover different types of events. A complete pre-employment picture requires both.
