Concrete-Anchored Mailbox Tests Roadside Safety Rules

Live Poll

Should homeowners be allowed to build mailboxes that withstand car collisions?

A Texas-area homeowner, Travis Howard, built a mailbox anchored by 6 x 6 posts set in about two and a half yards of concrete after the box was struck eight times in one year. A TikTok video of the structure has reached more than 4 million views.

Why it matters

Mailbox placement near roadways is a household safety and repair question, and the design choice that stops repeated damage can raise a different risk to drivers. Federal guidance calls for supports that break away on impact, so a heavily anchored mailbox sits in tension with that recommendation.

Howard's build uses 6 x 6 posts and about two and a half yards of concrete, far heavier than the 4 x 4-inch wooden or 2-inch pipe supports the Federal Highway Administration describes. The mailbox was hit eight times in a single year before he rebuilt it.

The players

United States Postal Service (USPS)

The federal mail carrier whose guidance says mailboxes should break away when struck by a vehicle.

Federal Highway Administration (FHWA)

The federal agency that sets roadside mailbox support specifications, including maximum wood and pipe sizes and burial depth.

The details

Howard enlarged the support hole each time the mailbox was struck and then poured concrete around the 6 x 6 posts to anchor it. The finished foundation extends about four feet deep and the assembly weighs approximately 4,000 pounds. The USPS states mailboxes should break away when struck by a vehicle, which is the opposite of the rigid anchoring Howard chose.

The Home Front

Several states, including Texas, North Carolina, Georgia, Montana, Florida, Kentucky, and Illinois, do not allow brick mailboxes, reflecting the same roadside-safety concerns behind federal support limits. Homeowners rebuilding after repeated strikes are working within those rules, not outside them.

If your mailbox sits near a road and has been struck more than once, check the USPS guidance on break-away supports before adding concrete or heavy anchoring. A licensed contractor can confirm that any change meets local rules before the work starts.

The takeaway

A mailbox built to resist every impact can shift the damage onto a driver, so the safer choice is a support designed to give way. Check your local rules and the USPS guidance before changing the anchoring.
