Which of the following is a control measure for trackout on site?

• A. Regular vehicle inspections
• B. Installation of trackout control devices
• C. Using smaller vehicles to avoid damage
• D. Restricting vehicle access at all times

Answer: (B)

The installation of trackout control devices is a control measure specifically designed to manage the transfer of dirt, dust, and other materials from construction sites onto public roadways. These devices, which can include gravel pads, wheel washes, and rumble strips, help to remove or minimize contaminants from the tires of vehicles before they exit a construction site. Properly implemented control devices reduce the likelihood of trackout, which can lead to dust emissions that contribute to air pollution and can create hazards for other road users.

Regular vehicle inspections may contribute to maintenance and safety but do not directly prevent the trackout of material from the site. Using smaller vehicles may reduce the volume of material transferred; however, it does not necessarily address the fundamental issue of trackout control. Similarly, while restricting vehicle access can limit trackout, it is often impractical and can hinder project operations. Therefore, the most effective and direct approach to manage trackout on site is through the installation of trackout control devices.
