Candidate Physical Ability Test (CPAT) Practice Test

According to NFPA 1901, the required percentage of chevron reflective striping on the rear of a fire vehicle is set at 50%. This standard is in place to ensure visibility and safety for both the emergency responders and the general public, especially in low-light conditions or during adverse weather. The reflective striping serves to make the vehicle more conspicuous, reducing the likelihood of accidents when a fire vehicle is parked at an emergency scene or during road responses. Using 50% striping achieves a balance between necessary visibility and the need for practical application on the vehicle's design.

In terms of other percentages, less than 50% would not provide adequate visibility, especially when compared to the increased safety benefits seen at the mandated level. Higher percentages such as 75% or 100% may not be practical or necessary in terms of design and utility. The NFPA guidelines aim to set standards that are both effective and feasible for fire departments to implement.
