To prevent trackout from construction sites onto public roads, which measures should be implemented at site access points?

• A. Implement stabilized entrances, scrape wheels, clean tires, and use wheel washes if necessary, with sediment controls at access points.
• B. Rely only on street sweeping after construction is finished.
• C. Place silt fences around the entire site boundary and ignore access points.
• D. Allow unrestricted vehicle movement across the site with no controls.

Answer: (B)

Stopping trackout happens at the point where vehicles leave the site. The most effective approach is to treat the site access as a control point: install stabilized entrances so soil isn’t picked up as vehicles enter and exit; have workers scrape mud off tires and clean tires before leaving; use wheel washes when needed to physically remove soil from wheels; and place sediment controls at the access to capture runoff and trap sediment before it reaches public roads. These steps prevent sediment from leaving the site in the first place, addressing the source of trackout right where it happens. Relying on street sweeping after construction is finished is reactive and often ineffective in practice, especially during busy periods, because soil can be deposited on roads before sweeping occurs and large volumes can be difficult and costly to remove. Similarly, placing silt fences around the entire site boundary without addressing access points misses the main route sediment uses to reach roads, and allowing unrestricted vehicle movement would exacerbate tracking. The core idea is to prevent sediment at the entry/exit itself, rather than trying to clean it up afterward.
