According to the Texas Department of Transportation, last year, drowsy drivers killed six people in Bexar County, and caused more than 600 crashes.
Emmy Morales, one of those affected by drowsy driving, said she's lucky to be alive.
Five years ago, a drowsy driver rear-ended the vehicle she and her husband were in and caused it to roll over several times. Her husband, Joseph, was killed on impact, and she sustained several broken bones and severe head injuries.
"I've had to undergo, to this date, 18 surgeries and, financially, it's hard because I'm no longer working," said Morales.
Morales says drowsy driving is just as dangerous -- or even more dangerous -- than drunken driving, because once you’re tired, your brain will have you go to sleep.
She said the driver admitted to police that he fell asleep at the wheel after he had several drinks at a party.
“It was several weeks that I was in the hospital, so I didn't attend my husband's funeral. I never got to say goodbye. We were together 27 years," said Morales.
These days, Morales is on long-term disability from work.
With the love and support from her family, she's been on the long road to recovery.
She says as a mother and grandmother, her life is full of love and joy, but not a day goes by where she doesn't think of her husband.
Morales is writing to her state representatives to try and get legislation passed so stricter laws will be in the books to prevent drowsy driving.
Factors for falling asleep at the wheel can be sleep deprivation, medication, or alcohol.
