What is wrong
Alamo Group, Inc. (Royal Truck) is recalling certain 2022-2026 Royal Truck & Equipment Class 2 Traffic Control trucks equipped with a Wanco sign board. The solar panel screws may loosen, resulting in a partial detachment.
The risk
A dangling or completely disengaged solar panel may hit other vehicles or pedestrians, increasing the risk of a crash or injury.
Why equipment defects matter: Equipment defects range from incorrect labels to fire and injury risks; the consequence summary says which applies.
The remedy
Royal Truck will provide instructions on how to remove the self-tapping screws and replace with rivets, free of charge. Owner notification letters were mailed September 29, 2026. Owners may contact Royal Truck's customer service at 866-975-0212.

What to do
- Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
- Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-502.
- Read the consequence summary carefully and stop using the affected equipment if the notice says to.
- Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.
Check by VIN
A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.
Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.
Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
