PennDOT DL-401CD: CDL Third-Party Examiner Application – If you are interested in becoming a certified Commercial Driver’s License (CDL) Third-Party Examiner in Pennsylvania, the official form you need is the PennDOT Form DL-401CD. This application is required for individuals seeking certification to administer CDL skills tests on behalf of approved Third-Party Testers under the Pennsylvania Department of Transportation (PennDOT) program. This guide provides current, accurate information based on official PennDOT resources for applicants across the United States, with a focus on Pennsylvania requirements.

What Is PennDOT Form DL-401CD?

Form DL-401CD is the official Commercial Driver’s License Third-Party Examiner Application issued by PennDOT. It is used by individuals applying to become new Third-Party Examiners, renew existing examiner certifications, or serve as CSTIMS (Commercial Skills Test Information Management System) Processors. The form collects personal information, employer details, testing site information, and required affidavits to ensure applicants meet federal and state standards under 49 CFR Part 383 and Pennsylvania Vehicle Code Section 1607.

Third-Party Examiners play a critical role in Pennsylvania’s CDL testing program by administering the same skills tests that PennDOT examiners conduct, helping expand testing capacity while maintaining high safety and integrity standards.

Who Needs to Complete Form DL-401CD?

You should complete Form DL-401CD if you fall into one of these categories:

  • Individuals applying as a new CDL Third-Party Examiner
  • Current examiners seeking renewal of certification
  • Employees designated as CSTIMS Processors who enter test results into the system
  • Examiners changing employment to a different PennDOT-approved Third-Party Tester (new certification is typically required)

Note that examiners must be payroll employees of an approved Third-Party Tester and cannot administer tests independently.

Key Eligibility Requirements for CDL Third-Party Examiners

Important Program Notes and Compliance

Third-Party Testers and Examiners must administer the exact same skills test used by PennDOT (vehicle inspection, basic control skills, and on-road driving). All testing data is entered into CSTIMS. PennDOT and the Federal Motor Carrier Safety Administration (FMCSA) conduct announced and unannounced audits. Failure to meet standards can result in decertification.

Examiners may only be certified under one Third-Party Tester at a time and must obtain new certification when changing employers. Immediate family members of the Tester owner are subject to specific restrictions.

Fees charged to CDL applicants for skills testing are set by the Third-Party Tester and must be market-driven. There is no cost to PennDOT under the program agreements.
