Description

Law enforcement officers use breath testing checkpoints, also called sobriety checkpoints, to stop drivers and assess their level of alcohol impairment. There are two types of checkpoints: selective breath testing (SBT), where officers must suspect a driver’s impairment to request a breath test; and random breath testing (RBT), where officers can test all drivers for blood alcohol levels. SBT is used in some US states; RBT is not used in the US. Checkpoints may be publicized through paid or unpaid media coverage, or occur without publicity (CG-Motor vehicle injury).

Expected Beneficial Outcomes

Reduced impaired driving
Reduced alcohol-related crashes
Reduced fatal and non-fatal injuries
Reduced underage drinking

Evidence of Effectiveness

There is strong evidence that sobriety checkpoints reduce alcohol-impaired driving, alcohol-related crashes, and associated fatal and non-fatal injuries, especially when highly publicized (CG-Motor vehicle injury, Lenk 2016). Positive effects have been shown for both random breath testing (RBT) (IAS-Anderson 2006, CG-Motor vehicle injury) and selective breath testing (SBT) (CG-Motor vehicle injury, Lenk 2016).

States with sobriety checkpoint laws have lower rates of alcohol-impaired driving than states without such laws. States that conduct checks frequently (i.e., at least monthly) have lower rates than states that conduct checks less frequently (Lenk 2016). The largest reduction in crashes often occurs in the first three to six months of checkpoint implementation (Erke 2009). A review of Australian checkpoints suggests that testing all drivers stopped at a checkpoint may increase the checkpoint’s effectiveness (Erke 2009).

Sobriety checkpoints are also a suggested strategy to reduce alcohol consumption among underage youth (RAND-Imm 2007, THM-Checkpoints 2014). However, additional evidence is needed to confirm effects on underage drinking.

Implementation

United States

As of 2015, 38 states and Washington DC permit law enforcement officers to conduct publicized random breath testing checkpoints by law; frequency and other specifics vary. Twelve states prohibit or do not authorize checkpoints (IIHS-Sobriety checkpoints).

Wisconsin

Sobriety checkpoints are prohibited by Wisconsin state statute (IIHS-Sobriety checkpoints).
