Reflective Tape and Marking

Reflective tape and emblems work around the clock without a battery, which is why they are a valuable part of making farm equipment easier to see. Where and how to use them depends on your equipment and your state.

How does reflective marking help?

Reflective materials send light from a vehicle's headlights back toward the driver. At night or in poor light they can reveal the shape, width and height of a machine from a distance.

Marking is most useful when it outlines the equipment, so another driver can read how big it is and which way it faces.

Marking works because the human eye is quick to notice a pattern of edges and corners. Even one clean strip along the back of a wagon can change how soon a driver reacts. Think of each strip as an early warning that costs little.

What is the slow-moving vehicle emblem?

The slow-moving vehicle emblem is a triangular sign used to show that a vehicle travels slowly. Its exact use, placement and any exceptions are set by state law and the manufacturer's guidance.

Confirm requirements with your state transportation department, highway patrol or extension office. Replace faded or damaged emblems, since a worn one does not do its job.

The emblem should be kept clean, clear of mud and facing the traffic behind you. If it is mounted where a load or implement hides it, ask the official agency or your extension educator about a better location.

Where should tape go on equipment?

Common practice is to mark the outer edges, corners and the rear of a machine and its implements so that the outline is visible from the front, back and sides. Extension publications explain placement in detail.

See the Iowa State University Extension guide on using reflective and fluorescent tape, and the eXtension ag safety article on visibility. Follow what they and your state require rather than guessing.

Walk around your equipment at night with a flashlight held at eye level, from far away, and note which parts stay dark. This simple check shows gaps quickly and helps you decide where to add or replace marking.

• Corners and outer edges of wide equipment
• Rear of tractors, wagons and implements
• Sides of long or towed equipment
• Any parts that stick out beyond the main body

What types of marking are there?

Reflective tape works well in the dark, while fluorescent materials are meant to stand out in daylight, dawn and dusk. Some products combine both properties. Ask a reputable supplier or your extension educator about what suits your equipment.

Do not mix up decorative stickers with marking products that meet the proper standards. Check the labeling and the guidance from the official source.

Be careful with older tape that has yellowed or cracked. Reflective ability fades with weather and age, so what was bright years ago may no longer do much. Replace it rather than trusting it.

How do I apply and maintain it?

Clean and dry the surface before application and follow the product instructions. Press the tape down firmly and avoid wrinkles. Remove old, peeling tape and replace it.

Check marking at the start of each season and after hard use. Mud, dust and crop residue can cover tape, so wipe it clean as part of regular maintenance.

Store tape and emblems in a clean, dry place and follow the manufacturer's directions on temperature and surface preparation. A well-applied strip lasts longer than a rushed one.

Does marking replace lights?

No. Marking is a supplement, not a substitute for lights, flashers and good driving habits. A driver who is not looking may miss both, so use them together.

Marking helps most in the case where lights fail, such as a dead battery or a broken wire. That backup role is one more reason to keep it clean and complete.

Think about layers of protection. Lights, marking, a clear driving plan, a trained driver and sensible timing together reduce risk far more than any single item does.

What else should I consider?

Think about trailers and implements that come off the machine. Each unit that travels on the road needs its own attention. Involve the whole family or crew so everyone knows what to check.

Keep a record of what you have installed and when. If you are unsure whether a product meets the rules, ask the official agency before you buy in bulk.

Consider including all-terrain vehicles and utility vehicles that sometimes use roadsides, and ask the official agency what rules apply to them. Smaller machines are easy to overlook and can be harder to see.
