Woman laughed at at Auto Zone proves size does matter when it comes to big truck booster seats

TikTok creator @cinicun10 shared an encounter at an AutoZone that turned a run-of-the-mill errand into a memorable exchange about assumptions and automotive accessories.

According to @Cincibun10’s video, she went into an AutoZone to run some diagnostics. As she exited the Autozone location with an employee who was helping her, everything seemed normal until he saw her truck.

Autozone guy busted out laughing

“As I’m walking the employee out to my car, the guy’s like, yeah, show me the way, ma’am,’” she recounts. But when they reached the truck, her size and her vehicle prompted an unexpected reaction. The employee began laughing loudly, “busting out laughing” and “bent over, grabbing his knees laughing,” she said, explaining that at first, she wasn’t sure why.

After a quick apology, he explained what amused him: “I didn’t expect to see a small woman like you driving a big truck like that,” she reports him saying. The laughter then escalated once more when she opened the driver’s door, and he noticed a booster seat. The employee “lost it again,” she said, adding that in the moment, she felt both embarrassed and amused.

Though she briefly questioned how to feel — “I’m embarrassed … I hope nobody’s watching,” she remembered thinking — she also laughed along and suggested she was glad to have given someone a moment of levity during a slow workday. In a later follow-up to a viewer’s request of a “truck and booster seat reveal ASAP,” @cinicun10 confirmed her vehicle setup.

Booster seats are for more than just children

@Cincibun10’s post stands out because many people associate strictly with children. In the U.S., booster seats are primarily regulated under child passenger safety laws and vary by state. Most state child passenger safety laws require children to remain in a booster seat until the age of 8 or until they’re 4 feet 9 inches tall — whichever comes first — because standard vehicle seatbelts are engineered for adult body proportions and often do not fit smaller passengers safely without elevation.

Safety experts generally recommend using a booster until the adult belt fits correctly without it, which involves the lap belt lying low across the hips and the shoulder belt crossing the shoulder and chest rather than the neck or face. This “fit” is crucial for occupant protection in the event of a crash.

However, it’s notable that there are no federal laws in the U.S. requiring adults to use booster seats, even for those small in stature. Some drivers use aftermarket seat cushions or adaptive seating solutions to help the existing seat belt fit more comfortably, or, in @Cincibun10’s case, see over the steering wheel. Most states’ traffic codes permit them as long as the belt itself is used properly.
