With just seven All-Star teams remaining on The Amazing Race, things are set to become more physical and competitive.

Mark Jackson & Mallory Ervin Say They Would 'Never Race Together Again?'

The drama between teams has been fairly light thus far, but a new traffic task in Sri Lanka could force some fierce battles during the reality hit's next episode, Down and Dirty.

A preview clip for the episode shows teams in a fierce competition during a roadblock task which will involve gassing up cars. To make the task more complicated, the members of each team who complete the task will also be forced to contend with excessive, and at times dangerous, traffic jams.

Teams Encounter 'Most Dangerous Leg Yet?'

Team members including Cord McCoy and John Erck are seen in the clip dodging between cars that nearly run them over, as they try to complete the task. Rachel Reilly also appears to encounter trouble during the task, as she starts pushing some of the smaller cars out of the way. The teams will also have a hard time as they try pumping gas into cars, which pull away before they can completely fill the tanks, splashing gas all over themselves in the process.

As he watches his father, Dave try to complete the task from the sidelines, Connor O'Leary voices what is likely going through everyone's heads at that moment.

"Absolutely insane," he says.

The teams may also potentially experience drama during a foot race to receive a clue, as they all try to enter a small doorway at once, which sees John fall to his knees in the process.

However, despite the increased competition, the teams will also likely see some of the more fun tasks during the leg, as they watch elephants lifting large logs with their trunks and placing them on platforms.

"Check that out, that is awesome," Jet says.

The Amazing Race airs Sundays at 8 p.m. on CBS.
