On the highway, an emergency apparatus should be parked at an angle so that

• A. The hazard from oncoming traffic is reduced and the tailboard protects workers
• B. Traffic is blocked to provide protection
• C. The apparatus is kept as close as possible to the incident
• D. The headlights are aimed at oncoming traffic

Answer: (A)

Positioning the emergency apparatus at an angle on the highway creates a protective buffer between workers and passing traffic while still alerting and guiding drivers past the scene. The tailboard acts as a physical shield for workers in the work area, reducing exposure to the hazard from oncoming vehicles. This setup minimizes risk and allows responders to operate more safely. Blocking traffic to a complete stop, getting the vehicle too close to the incident, or aiming headlights directly at oncoming traffic would increase risk or create glare and distractions rather than provide protection.
