If you drink and drive this holiday weekend, you will go to jail.

That is the message local agencies and law enforcement are pushing ahead of Labor Day Weekend.

According to the Texas Department of Transportation, Harris County leads the nation in drunk driving fatalities. This weekend, officials from the Houston Police Department and Harris County Sheriff's Office said officers will saturate drunk driving hot spots.

"As long as we're out this weekend, we are going to make sure your families come home safe," HCSO Capt. Nancy Hennessy said.

The announcement came Friday -- the day after several overnight alcohol-related crashes.

Shortly after 9 p.m. Thursday, a woman was charged with driving while intoxicated after she drove into an officer's patrol car on Broadway at Morley near Hobby Airport, police said. A little while later, another "highly intoxicated" woman crashed on Texas 249, according to officials. A third accident happened at about 3 a.m. Friday when a man was charged with DWI after driving the wrong way on F.M. 288., police said.

HPD planned to start patrols at 4:30 p.m. Friday, targeting happy hour patrons on Washington Ave.

People who do not have a designated driver are encouraged to call a cab. Patrons in Midtown, The Heights and the Washington Corridor can call the Washington Wave jitney cab service at 713-863-WAVE (9283) to avoid getting a DWI.
