The bright signs—fluorescent orange triangles bordered with reflective red—are mounted on the rear of tractors and implements traveling slower than 25 miles an hour to warn motorists of the slow-moving vehicle.
Many Maine growers and farm workers are moving equipment, livestock, hay and crops with tractors, and on public roads this can be a dangerous situation. The reflective border of the SMV sign defines the shape of the fluorescent color in daylight, and creates a hollow red triangle when illuminated by headlights at night.
Farmers collecting the signs also receive a safety packet about how to use the sign and about the use of tractors on public roads. Growers can then pick up their sign or signs—up to two a farmer—at their nearest participating farm-equipment dealer before June 1.
