Frequently Asked Questions (FAQs)


Course Introduction

Construction contractors, contracting agencies, and others responsible for work zone safety face the challenge of providing a safe workplace while ensuring the safe movement of the public through the work zone. Highway and street construction presents a complex work situation in which workers face multiple injury risks under conditions that may change without warning.

This training conforms with OSHA's recommendation that training should focus on identifying recognized hazards, analyzing the causes of accidents, and controlling hazards to prevent accidents. OSHA does not want safety training to focus only on its rules. If you are an employer, it is your responsibility to provide additional training for workers on the specific hazards of their job as noted in OSHA Pub 2254, Training Requirements in OSHA Standards and specific work zone rules in your state. If you are an employee, it is your responsibility to comply with your employers safety policies, procedures, and rules.

OSHA holds employers accountable to provide additional training for workers on specific hazards of their job as noted in OSHA Pub 2254, Training Requirements in OSHA Standards and specific work zone rules in your state. If you are an employee, it is your responsibility to comply with your employers safety policies, procedures, and rules.

Because interpretations and enforcement policy may change over time, consult current regulations for additional guidance compliance requirements. Click on the button to see recommended regulations and guidelines for review.

  • OSHA construction rules within industry standard, 1926, Subpart O, address operation of vehicles and equipment within an off-highway job site not open to public traffic. However, Subpart O is not exhaustive in its coverage of machinery types or safety equipment, nor does it address work practices, traffic control plans, or shift work.
  • Flagging and signaling practices covering signs, signals, and barricades, are discussed in general terms in 1926 Subpart G. Subpart G defers to the U.S. Department of Transportation's "Manual on Uniform Traffic Control Devices MUTCD" on matters relating to hand signals, barricades, and traffic control devices.
  • You can learn more about the laws applicable to work zones in your state at the National Work Zone Safety Information Clearinghouse.

Course 612 Final Exam

Exam score sheet

After studying the course material and answering the quiz questions, it is time to take the final exam. We highly recommend answering the module quiz questions to check your understanding of the course material. The final exam questions are typically developed from these quiz questions.

OSHAcademy course final exams are designed to make sure students have gained a sufficient understanding of the content covered within each course. To help demonstrate this understanding, students must achieve a passing score on course final exams. It is OSHAcademy's policy to protect the integrity of our exams: as a result, we do not provide missed questions to students.

This is an open book exam. Students are permitted to use a separate browser window to review course content while taking the exam. If you do not pass a final exam, you will see a "Retake Exam" button next to the course on your student dashboard.

If you have already paid for your certificate

If you have already paid for certificates, your exam score will be displayed on your student dashboard after successfully passing the final exam. If you chose PDF certificates, you can view and print your certificate and personal transcript from your student dashboard. If you chose original printed documents, they will be prepared and mailed to the address in your student account.

If you only want free training

OSHAcademy provides free access to all training materials, including course modules, practice quizzes, exercises, and final exams. However, exam scores, certificates, and transcripts are provided only if you purchase a certificate package to document your training. If you do not require official training documentation, we will archive your exam results should you decide to purchase official certificates later.
