Britain's Christmas Crusade against drinking and driving

Area of Science:

• Criminology
• Public Health
• Traffic Safety

Background:

• The 1983 "Christmas Crusade" in Great Britain involved widespread police breath testing for drunken drivers.
• Public perception characterized the campaign as a national, organized deterrent effort, despite a lack of deliberate planning.
• Deterrence theory suggests increased certainty of punishment can reduce illegal behavior.

Purpose of the Study:

• To evaluate the deterrent effect of the 1983 "Christmas Crusade" on drunken driving.
• To test the hypothesis that the publicized campaign reduced alcohol-related traffic accidents.

Main Methods:

• Analysis of automobile crash-related fatality data during the period of the crusade.
• Utilizing the index of total automobile crash-related fatalities as the primary metric.
• Comparing fatality rates during the crusade month with baseline periods (implied).

Main Results:

• A significant decline in the index of automobile crash-related fatalities was observed during the crusade month.
• The findings provide statistical support for the hypothesis that the campaign had a deterrent effect.
• The reduction in fatalities suggests the intervention was effective in curbing drunken driving.

Conclusions:

• Highly publicized campaigns that increase the certainty of punishment can be effective deterrents for illegal behavior.
• The "Christmas Crusade" experience supports the efficacy of visible enforcement and public awareness in reducing drunken driving.
• Deterrent interventions are most effective over a limited duration, highlighting the need for sustained efforts.
