HOUSTON --The Harris County District Attorney's Office is putting people who drink and drive on notice. The No Refusal weekends program will now run not just during upcoming holiday weekends, but every weekend for the next three years. The change started in November after Harris County received a three-year grant from the Texas Department of Transportation to run the program. As you may know, if you're pulled over and refuse a breath test, the program makes judges available so law enforcement can easily obtain a warrant for a blood draw. So far, the DA's office says they are looking at the early numbers from November and there were consistently higher levels of alcohol reported for those who declined breath tests and had their blood drawn. "It certainly seems to suggest that the folks who really know that they shouldn't have been on the road, that they shouldn't have been endangering the other citizens of the community, are trying to withhold that evidence," said Catherine Evans Chief Prosecutor, Vehicular Crimes Section. For the month of November, 299 DWI charges were filed and 97 of those involved warrants for a blood draw.
