Who is primarily responsible for enforcing safety regulations?

• A. Supervisor
• B. Inspector
• C. Motorist
• D. Pedestrian

Answer: (A)

The main idea here is who is responsible for making sure safety rules are actually followed on the job site. On a bridge work site, the supervisor is the one who must ensure every crew member adheres to safety rules, uses personal protective equipment, follows approved procedures, and addresses hazards before and during work. The supervisor also has the authority to stop work if conditions are unsafe, which is the essence of enforcing safety practices in real time.

An inspector’s role is to assess compliance and identify hazards, often during audits or checks, but they aren’t the daily enforcer on the site. Motorists and pedestrians don’t have enforcement authority, so they aren’t responsible for enforcing regulations.
