Step-by-step explanation:
The high visibility markings required in the NFPA standards apply to emergency vehicles.
Emergency vehicles such as fire trucks, ambulances, and police cars need to be easily seen by other drivers, especially in emergency situations. The high visibility markings, often in the form of reflective materials or fluorescent colors, help increase the visibility of these vehicles on the road.
For example, fire trucks typically have red and white reflective striping, while ambulances often have a mix of red and fluorescent yellow-green markings. These markings allow other drivers to quickly recognize the presence of emergency vehicles and take appropriate actions to make way for them.
