Evidence-Based Practice |
| Description |
At sobriety checkpoints, law enforcement officers use a system to stop drivers to assess their level of alcohol impairment. There are two types of sobriety checkpoints: (1) random breath testing (RBT) checkpoints where officers randomly select and test drivers for blood alcohol levels; and (2) selective breath testing (SBT) checkpoints where officers must have reason to suspect a driver has been drinking before testing. SBT is the only type of sobriety checkpoint used in the United States.
The Community Preventive Services Task Force recommends sobriety checkpoints based on strong evidence of their effectiveness in reducing alcohol-impaired driving, alcohol-related crashes, and associated fatal and nonfatal injuries. |

Results from the Systematic Reviews:
Twenty-three studies qualified for the review.
• Crashes thought to involve alcohol: median decrease of 18% for RBT checkpoints (interquartile interval: 22% to 13% decrease; 11 studies) and 20% for SBT checkpoints (interquartile interval: 27% to 13% decrease; 10 studies)
• Fatal crashes thought to involve alcohol: median decrease of 22% for RBT checkpoints (interquartile interval: 36% to 13% decrease; 6 studies) and decreases of 26% and 20% for SBT checkpoints (2 studies)
• Crashes declined regardless of the follow-up time of the study, with median decreases of 18% for follow-up times of less than one year and 17% for follow-up times of more than one year. |
