What color is the slow moving vehicle emblem?

• A. Red
• B. Bright fluorescent orange
• C. Blue
• D. Green

Answer: (B)

The key idea here is the visibility cue for slow-moving vehicles. The slow moving vehicle emblem is bright fluorescent orange because that color is highly visible in daylight and at night, helping drivers notice vehicles that are traveling slowly and may be farther ahead than they appear. This glare-free, attention-catching color is chosen specifically to warn others to slow down and be prepared for a vehicle that isn’t moving fast. Red, blue, or green are not used for this emblem because they don’t convey the same immediate warning signal for slow speed, and they’re associated with other meanings on signs and lights.
