Anley 18×18 Inch Orange Warning Sign Safety Flags

The Anley flag set is designed to conform with typical DOT guidance requiring at least 18-inch square warning flags for wide or projecting loads. The product description notes that one flag is required when the load is two feet wide or less, and two flags for wider loads. The flags use a mesh construction that allows wind to pass through, reducing flapping, and are vinyl-coated for weather resistance. This combination supports long-term outdoor use and easy deployment on rear ends of vehicles.
Features include: fluorescent orange color for high visibility, a lightweight feel, and durable, foldable construction. Mesh material minimizes wind resistance, helping prevent flag damage during transport. For operators who haul oversized loads regularly or want better rear visibility, these flags offer a practical, cost-effective option with reliable performance in varying weather conditions.
18×18 EZ Mount Warning Flag With Mounting Kit

This DOT-compliant flag set emphasizes secure mounting with a stainless steel mounting bracket. Red-orange safety flags align with regulatory requirements for oversize loads, presenting a robust solution for frequent haulers. The durable jersey mesh fabric provides resistance to water damage and reduces tearing from road debris, keeping flags intact across seasons. The stainless steel bracket ensures lasting attachment to trailers and trucks while resisting rust and dings common on job sites.
2 Pack High Visibility Safety Flag

These red warning flags prioritize multi-angle awareness with reflective stripes, making them highly visible from various approaches. The set includes two flags sized to be easily mounted at the rear of trailers or trucks, and the dark webbing aids secure attachment. The product emphasizes foldable, lightweight construction while maintaining bright color fidelity and resistance to wind-induced wear, making them suitable as quick-replace options for frequent users.
Notes on usage: Always ensure flags are securely mounted away from moving parts and that reflective elements are clean for maximum daytime and nighttime visibility. Regular inspection is recommended to confirm grommets and attachment points remain intact after long hauls and exposure to road grime or salt.
FYWZ Magnetic Safety Flag (4 Set)

The FYWZ set uses strong magnets with a rubber-coated finish to resist corrosion and prevent paint scratching on metal surfaces. Each flag is a 18 x 18 inch red mesh design, making it suitable for trucks, trailers, and other large equipment on a wide range of surfaces. The magnets offer up to 60 pounds of pull force, which helps maintain visibility on uneven roads or when attached to metal structures. The PVC construction ensures durability against weather, with treated hems to reduce tearing over time.
Newwiee 12 Pack 18 x 18 Inch Flags

Newwiee provides a bulk option with twelve flags, each featuring two sturdy metal grommets for reliable mounting. The red flags are designed to be weatherproof and windproof, with a polyester material that resists fading and tearing. The high quantity is ideal for operators who regularly outfit multiple loads or need immediate replacements after long trips. The flags are clearly visible from a distance and suitable for rear mounting on trucks, cars, and trailers to improve safety at road crossings and work zones.
Orange Safety Flags For Trucks With Bungee Core

These 18×18 inch orange flags emphasize a mesh design for high visibility and long-term use. The bungee core provides added flexibility to absorb wind gusts without tearing the flag itself. Made from durable nylon mesh, they withstand outdoor conditions and fading, making them suitable for extended outdoor exposure. They are presented as multipurpose flags that can be used for different transportation needs, including trucks and trailers hauling wide or long loads.
Buying Guide
Key considerations for selecting safety flags for long loads:
- Size and visibility: 18×18 inches is the standard for regulatory compliance in many regions; ensure the flag is large enough to be seen at typical traffic speeds and distances.
- Material and durability: Look for weatherproof fabrics like PVC-coated nylon or polyester with UV resistance to minimize fading and tearing from sun, rain, and wind.
- Attachment method: Grommets, mounting brackets, or magnetic mounts affect ease of installation and stability. Stainless steel hardware resists rust for longer life.
- Wind resistance: Mesh designs allow air to flow through, reducing flapping and wear. Consider flags with reinforced hems to extend life under gusty conditions.
- DOT and safety compliance: Verify flags are designed to meet relevant regulations in your region, and that mounting hardware supports regular road use.
- Quantity and replacement plans: If you transport wide loads frequently, a bulk pack reduces downtime for replacements and ensures you always have a spare flag ready.
- Versatility: Some flags are adaptable to multiple mounting styles (brackets, hooks, or magnets). Choose options that fit your vehicle type and maintenance preferences.
When selecting flags for long-haul applications, align product features with your typical routes, weather exposure, and the level of visibility you need at dawn, dusk, and nighttime. For fleets, consider bulk packs to standardize equipment across vehicles and simplify maintenance schedules. Always store flags properly when not in use to extend their lifespan and maintain high-visibility color.
