GARLAND (CBSDFW.COM) – Two Garland women who were trapped inside their sinking vehicle Friday after mistakenly driving off a boat ramp at Lake Ray Hubbard say they know they could’ve drowned.

Twenty-year-old Ngoc Do was at the wheel.

“I was on the phone with my dad,” Do said.

She was asking him for directions to Interstate 30.

Her 21-year-old cousin, Nhi Tran, was in the passenger seat. The two then turned onto a road. Or so they thought.

“It was scary because I was lost and I didn’t see the water,” Do said.

They never saw the poorly placed signs that they had driven onto a boat ramp until they plunged into the water.

“I saw the water first. I was just screaming, like ‘Ahhhhhh!'” Nhi Tran said.

“She was, like, ‘Ahhhhh.’ Then, we realized we was in the water,” Do said.

Rockwall Officer Kevin Roland, they say, just happened to be in the area and saw their vehicle lights in the water.

“I just tell her to calm down. Because I saw the officer

was swimming toward us. And, I just thought, ‘Oh,

we are safe,'” Do said.

Roland waded in, broke a window to free them and then carried them both to solid ground. Neither woman knew how to swim.

“I’m really happy the officer save us. And I thought it was God who save our life,” Do said.

Both have something to say to the officer when they see him again.

“Thank you. Thank you very much,” said Tran.

“Thank, I really thank him. He was heroic,” Do said.

The two young women will be able to thank the officer in person at a ceremony at 7 p.m. Wednesday morning at the Prestonwood Country Club.

Both women speak Vietnamese as their native language, though Ngoc Do also speaks French having lived in Canada for nine years.

Both are attending English classes at Richland College with the hopes they’ll become real estate agents.
