Objective: To know the proper use of the Slow Moving Vehicle (SMV) emblem.
By law, farming equipment must display an SMV emblem when moving on roadways at less than 25 mph. Point out the advantages of using the SMV. Demonstrate how to attach the sign correctly. Compare SMV signs in good repair with unacceptable damaged or faded signs. Review the true or false quiz.
SMV signs are required by law on farm machinery and equipment and animal-drawn vehicle traveling on roadways at speeds of 25 mph or less and must be visible for at least 500 feet to the rear. In Ohio, approved SMV signs have a front label identifying the manufacturer and documenting that the sign meets the American Society of Agricultural and Biological Engineers’ (ASABE) standards for durability and longevity.
Properly mounted, the sign is centered, 2 to 6 feet above the ground, pointed up, and in a place perpendicular to the direction of travel.
Slow Moving Vehicle Emblem (SMV)
Traffic studies show that two out of three highway incidents involving slow moving vehicles are rear-end collisions and that 90% of these accidents happen during daylight hours. The use of the SMV sign reduces incidents and saves lives. Signs in poor condition provide little or no protection in traffic. Keep the sign clean for maximum visibility. Replace damaged or faded signs immediately. Remove, cover, or turn SMV signs when tractors are transported on another vehicle. A faded sign will not be visible for the required 500 feet. When this occurs, the tractor or farm machinery and the operator’s life are in danger and the law is violated. To extend the life of the SMV, always cover or keep the sign out of the sun when not using the piece of machinery.
The bright, fluorescent orange triangle of the SMV sign is visible for more than 1,000 feet (one-fifth of a mile) providing motorists ample time to slow down. At night, the reflective red border of the SMV sign is illuminated by approaching headlights, immediately identifying a slow moving vehicle.
Review The Following Points
- Keep the sign clean to enhance visibility.
- Replace faded or damaged signs.
- Mount the sign, point up, between 2 and 6 feet above the ground.
- Place the sign close to the center of the equipment.
- Ohio law defines a slow moving vehicle as traveling at speeds of 25 mph or less.
