Steven Litvintchouk oversees the editorial quality of Driving-Tests.org’s practice-question banks for cars, commercial vehicles, and motorcycles nationwide.

He has edited and corrected most of our existing items, authored new content for FMCSA Entry-Level Driver Training (ELDT), and keeps materials current as laws and handbooks evolve.

Previously, Steven spent 24 years in computer engineering and technical documentation, publishing peer-reviewed work and leading large-scale defense and aerospace software projects.

He holds an M.S. from MIT (1978) and a B.S. from Columbia University (1975). Today he also researches and annually updates national reports on U.S. driving statistics.

Areas of responsibility and expertise

  • Editorial lead for car, CDL, and motorcycle practice tests (question wording, hints, explanations, illustrations).
  • ELDT: development of new question sets for FMCSA Entry‑Level Driver Training.
  • Annual research and updates for U.S. driving‑statistics reports.
  • Visual accuracy: upgrade of CDL graphics to modern 3D modeled imagery; supported transition from 3ds Max → Blender.

Methodology

How Steven reviews our content

Scope of review

For each affected state/topic, Steven reviews item wording, explanations, terminology, correct/incorrect options, pass mark notes, age/eligibility requirements, and any sign/marking depictions.

Sources of truth
  • State Driver Handbook (latest edition)
  • MUTCD (signs/markings)
  • Relevant state code and Code of Federal Regulations (FMCSR for CDL)
  • Official DMV bulletins/updates

Change detection

Constant monitoring of official sources using automated alerts and internal checks; when an official change is confirmed and reflected in authoritative materials, impacted items are queued for review.

Review steps

Content diff
Source check
Clarity/readability pass (ESL friendly, plain English)
Visual audit (signs/graphics)
Editor sign off

Versioning and timestamps

Each page shows Last verified for accuracy (editor verification date).

User feedback loop

Reported issues are triaged; if sources conflict, we defer to current state handbooks and controlling statutes.

Source notes (what Steven relies on)
  • State DMV/RMV handbooks (by edition)
  • MUTCD (FHWA) for signs and roadway standards
  • State statutes and the CFR for CDL/ELDT topics
  • DMV notices and public guidance pages

Editorial policy

  • Editorial independence: Driving-tests.org operates independently from state DMVs and driving schools. Our content is reviewed against official government sources only, with no commercial influence on question accuracy.
  • Update process: We monitor official DMV sources weekly. When changes are detected in state handbooks or regulations, affected questions are reviewed and updated within the same week.
  • Report errors: Found a mistake? Use the "Report a mistake" link on any test question - we investigate all reports and respond within 48 hours.

Recent highlights

Edited and corrected the majority of our current practice question database; authored numerous ELDT items.

Led the upgrade of CDL imagery to consistent 3D assets; supported toolchain migration to Blender.

Initiated online multimedia courses for commercial‑driver training (general knowledge, hazmat, passenger, school bus).
