What color is an emergency vehicle?

  1. Blue

  2. Red

  3. Yellow

  4. Black

The correct answer is: Red

Emergency vehicles are commonly associated with the color red because it is a highly visible color that is easily recognized by drivers on the road. This color is commonly used for fire trucks, police cars, and ambulances to help them stand out and be easily identifiable in case of an emergency. Blue, which was not the correct answer, may be used for law enforcement vehicles in some areas, but is not as standardized as red. Yellow may also be used for construction and traffic control vehicles, but this is not specific to emergency vehicles. Black, the final option, is not typically used for emergency vehicles as it is not a highly visible color that would help alert other drivers on the road. Therefore, red is the best answer for the color of an emergency vehicle.
