The driver of a sedan on a freeway is seen attempting to change lanes in front of a semitruck. The driver learns the hard way that because semis are so much heavier than regular cars, they cannot brake as fast.

Watch what happens in this video posted by TikTok user @cdllife.


The video poster explains that, thankfully, everyone was okay after this incident. 

"Do people not understand that semis can’t slow down as quickly as regular cars?" a user asks.

"The car literally had no reason to hit the brakes," another says. "Why do people hit the brakes for no reason?"

One viewer of the video takes a contrarian opinion. "The truck should have slowed down," he writes.

"Wrong again," another responds. "Illegal lane change from car. Trucker can win this one."

Another agrees: "For those saying it’s the truck's fault, y'all need to get your license revoked."

"Why would you ever brake check a truck?" a perplexed user asks. "You’re not going to win."

"Bet they won't brake check a semi again," says a video watcher.

"The right lane ends. Look at it," someone suggests. "The car should have sped up and not braked, but the truck was the one that had to merge and should have slowed down."

This reader is a bit puzzled: "I can’t fathom how people brake check a truck. I get scared being next to it. They're deadly in accidents."

You would never catch me that close to a semi in my life," writes a user that seems to agree. "Always let them pass."

"Why do people think its funny to mess around with 18-wheelers like they aren't going get mowed over?" another asks.

One user observes something a bit ironic: "Anyone else notice the truck that said 'The end' close to the end of the video?"
