How DUI checkpoints work to keep you safe

Posted on October 23rd, 2017 / By Matthew Kenny

Intoxalock - DUI CheckpointsAs the year winds down and we find ourselves in the midst of the busiest holidays for traveling, we will likely see a variety of different sobriety checkpoints being performed across the nation. These checkpoints are performed in predetermined locations and allow law enforcement officers to stop vehicles to check whether drivers are impaired.

Effectiveness of checkpoints

Though not performed in every state of the United States, only 38 states currently conduct them, these checkpoints have been proven to decrease alcohol-related injuries and property damage, saving lives and money in various communities nationwide. In 2002, The Center for Disease Control and Prevention performed a systemic review of 11 sobriety checkpoint studies and quantified that these checkpoints reduce alcohol-related injuries and property damage by about 20 percent. More recently, in 2011, a study was performed that examined the exact effectiveness of 22 DUI checkpoints orchestrated over one year in 2011. The conclusion of this study found that the rate of impaired collisions in post-checkpoint periods was about 19 percent less than in the pre-checkpoint periods. Studies like the two referenced above are just two exemplars of the boon provided by these checkpoints.

Even the costs associated with these checkpoints hold positive returns to local communities. As mentioned in this sobriety checkpoint fact sheet released by Mothers Against Drunk Driving (MADD), research has shown that for every dollar invested in checkpoints, these communities save between $6 and $23 in costs from alcohol-related crashes.

With all the benefits these checkpoints provide, whether it be reducing driving impairment rates or saving money in alcohol-related crashes, it is hard to find a reason against performing DUI checkpoints in local communities. If you end up going through a DUI checkpoint in your immediate area and are asked to pull your vehicle over for inspection, remember all the positives listed above that they provide and how much safer the roads in that area are because of them.

Sobriety checkpoints: A deterrent to driving while impaired?

Posted on January 11th, 2017 / By Carly Flaws

In 2015, Alcohol-impaired drivers caused over 10,000 traffic fatalities in the United States, making up 20% of all traffic fatalities (National Highway Traffic Safety Administration). One common practice to help deter the incidence of drunk driving is sobriety checkpoints. Currently, 38 states and the District of Columbia authorize sobriety checkpoints (NHTSA).

According to the Center for Disease Control (CDC), a sobriety checkpoint is held at a predetermined location at which law enforcement officers stop vehicles to check whether the driver is impaired. They may stop every vehicle or stop vehicles at a set interval.

Data suggests that sobriety checkpoints act as a deterrent to driving after drinking by increasing the perceived risk of arrest. The threat of a checkpoint helps to reduce the drivers’ confidence that they can avoid getting caught for driving while intoxicated. The CDC identified that checkpoints can help reduce alcohol-related crashes and fatalities by 18%-24%.

Alcohol-impaired driving and perceived risks of legal consequences

This month, an article entitled, “Alcohol-Impaired Driving and Perceived Risks of Legal Consequences” was published and revealed that perception of risk was a key factor in individuals deciding whether or not to drink and drive. The researchers analyzed data collected from drivers, the police and defense attorneys specializing in driving while impaired (DWI) cases from eight different cities in the United States.

First, researchers asked individuals whether sobriety checkpoints or legal penalties following drunk driving were more frightening. Next, researchers asked individuals if there was an increase in either checkpoints or tougher legal penalties, which would help deter them from driving under the influence.

Results

The results of the research discussed above suggest that checkpoints are an effective deterrent for individuals who drink and drive. This data helps to support Intoxalock’s belief that ignition interlock devices should be required for all drunk driving offenders. Regardless of the laws, research is consistent in showing that license suspensions are extremely ineffective in preventing people from continuing to drive. As revealed in this study, people will still continue to take chances unless there are additional measures such as ignition interlocks and police checkpoints stopping them.
