Truck Apron

Curb radii at intersection corners are designed to accommodate all vehicle types. Typically, many intersection corners are designed for larger vehicles, which enables smaller vehicles to turn at a higher speed than desired. Truck apron is a mountable curb alignment to reduce turning speeds for smaller vehicles. Meanwhile, this treatment accommodates a larger corner radius to allow larger vehicles to go over the truck apron when making right turns. The design of the truck apron should discourage pedestrians and cyclists to use them as a safe queuing area.

Application/Considerations/Outcomes

• Should be visually distinct from the adjacent travel lane, sidewalk and bike facility
• Height of the mountable areas and curbs should not exceed 3 inches above the travel lane
