Why is parking prohibited within 25 feet of a motorists courtesy mailbox?

Parking is prohibited within 25 feet of a motorist's courtesy mailbox primarily to ensure that postal workers can access the mailbox safely. This designated distance provides adequate space for postal vehicles to stop without obstructing traffic or creating hazards for both the postal worker and passing vehicles. The clearance encourages safe and efficient mail delivery, allowing postal workers to approach and access mailboxes without having to navigate around parked vehicles. This consideration not only facilitates smooth operations for postal services but also contributes to overall roadway safety by minimizing potential conflicts between vehicles and pedestrian traffic, particularly in residential areas where mailboxes are commonly located.
