Snow removal vehicles have flashing lights of the following color:

  1. Red

  2. Yellow

  3. Green

  4. Blue

The correct answer is: Blue

Blue lights are used on snow removal vehicles because they are highly visible in low light or poor weather conditions. Red lights are typically used on emergency vehicles and may cause confusion for drivers on the road. Yellow lights are often used for caution or warning purposes, but may not be as visible in snowy weather. Green lights are primarily used for non-emergency vehicles and may not signal urgency for a snow removal vehicle. Therefore, blue lights are the most appropriate choice for snow removal vehicles.
