Minimize Danger Zone

The Minimize Danger Zone Shield (or MDZ Shield) is an affordable and proven new solution to eliminate the danger zone gap surrounding the right dual wheels of the school bus. 

The “danger zone” refers to the area extending 10 feet to the front, rear and sides of the school bus, where children are at most risk of being hit by passing vehicles or by their own bus.

After 20 years of success in danger zone safety, Public Transportation Safety International is now determined to make the MDZ Shield an industry standard, and is working with school bus OEMs to ensure its standardization.

Manufactured at TPC Urethane in Fontana, California, the MDZ Shield is a casted, high-performance BASF polyurethane shield that acts as a physical barrier in front of the rear dual wheels, designed to deflect a child out of the path of the school bus, preventing catastrophic injury or death.

The shield is easily and quickly mounted to the side of the bus around the wheel well opening, lessening both material and labor costs while making it easily visible for inspection. Its firm, durable finish is resistant to scratches, cracking, peeling, UV rays, and dust, and can withstand any road condition or terrain, in any season. The MDZ Shield was designed to withstand curb impact, and is built to last for the lifespan of the bus.

Inventor Mark Barron and PTS, developer of the widely deployed S-1 GARD for transit buses, are pleased to introduce the MDZ Shield, and believe it will finally close the school bus danger zone gap.
