• Safety Features: These boards follow MUTCD rules. Covers and reflective borders protect the board and help you see it at night.

Arrow boards are special because they use all these features to give clear, reliable messages to drivers.

How Arrow Boards Work

Arrow boards use bright LED displays to show traffic warning arrows and other symbols. When you get close to a work zone or lane closure, you see arrows showing you where to go. The LED lights are much brighter than old bulbs. This helps you see the signals from far away, even in bad weather or at night. LEDs also last longer and use less energy, so the boards need less fixing and always work well.

You get help from the high-brightness and ultra-bright LED lights, especially in Type B and Type C arrow boards. These types keep the traffic warning arrows easy to see in any weather, like fog or rain. Where workers put the board is important, too. If the arrow board is in the right place, you have enough time to react to changes on the road. This helps stop confusion and keeps people from making sudden lane changes or having accidents.

Arrow boards can show messages like “Lane Closed” or “Detour Ahead.” But their main job is to show clear traffic warning arrows. These arrows help you drive safely through changing road conditions. The boards help with traffic management by making sure you always know what to do.

Note: Arrow boards help make roads safer, improve traffic flow, and lower accident numbers. You can trust these traffic control devices to keep you and others safe on the road.

Types of Arrow Boards

Portable Arrow Boards

Portable arrow boards are easy to move and set up fast. You often see them on trailers or small vehicles. They help control traffic during road work or emergencies. You can use them for special events, too. When traffic needs to change quickly, these boards show clear traffic warning arrows. They follow MUTCD standards, so they are safe and reliable.

Here is a simple table that compares the main types of arrow boards and how they are used:

Vehicle-Mounted Arrow Boards

You see vehicle-mounted arrow boards on trucks and utility vehicles. These boards help guide traffic while the vehicle moves or works. They use strong mounts, like bed rails or rooftop frames, to stay in place. Many boards fold down for storage. You can control the traffic warning arrows from inside the cab or with a remote. Some boards have up to ten arrow patterns for different needs. The boards use tough materials and connect to the vehicle’s power. This makes the traffic warning arrows easy to see in any weather.

• Vehicle-mounted arrow boards have:

• Strong mounts for trucks and utility vehicles

• Electric tilt frames for folding and storage

• In-cab or wireless controls for changing patterns

• Lights that work well day or night

Solar-Powered Arrow Boards

Solar-powered arrow boards use sunlight to run the traffic warning arrows. You can use them for long projects or where there is no outside power. The solar panels work even when it is cloudy, so the board stays on in bad weather. Some boards have backup batteries for night or low sunlight. Solar-powered arrow boards save energy and help the environment while keeping roads safe.

Tip: Solar-powered arrow boards are great for remote places or long road jobs.
