About
Provides statistical metrics relating to fatal driver collisions across states within the United States. The data quantifies critical factors such as the rate of drivers involved in fatal incidents per billion miles travelled, alongside the proportion of those collisions linked to speeding, alcohol impairment, and lack of distraction. It also incorporates related economic metrics, including average car insurance premiums and the losses incurred by insurance companies per insured driver. This data serves as the foundation for examining state-level safety differences and associated financial impacts.
Columns (List and describe each column found in the 'Original Data Sample'.)
- State: The US State or jurisdiction to which the statistics apply.
- Number of drivers involved in fatal collisions per billion miles: The rate of fatal collisions relative to the distance travelled in the state (Source: NHTSA, 2012).
- Percentage Of Drivers Involved In Fatal Collisions Who Were Speeding: The percentage of drivers in fatal collisions where speeding was a factor (Source: NHTSA, 2009).
- Percentage Of Drivers Involved In Fatal Collisions Who Were Alcohol-Impaired: The percentage of drivers in fatal collisions found to be impaired by alcohol (Source: NHTSA, 2012).
- Percentage Of Drivers Involved In Fatal Collisions Who Were Not Distracted: The inverse percentage showing how often distraction was not recorded as a factor (Source: NHTSA, 2012).
- Percentage Of Drivers Involved In Fatal Collisions Who Had Not Been Involved In Any Previous Accidents: The proportion of drivers in fatal incidents who had clean prior records (Source: NHTSA, 2012).
- Car Insurance Premiums ($): The average cost of car insurance premiums in the state (Source: NAIC, 2011).
- Losses incurred by insurance companies for collisions per insured driver ($): The financial burden on insurers due to collisions, calculated per insured driver (Source: NAIC, 2010).
Distribution
The dataset is structured as a CSV file, named
bad-drivers.csv, with a small file size of 2.58 kB. It contains 8 distinct columns and features 51 unique records, covering all US states. All records are valid, with 100% data availability and no missing values across any of the columns.Usage
This data is ideal for applications requiring state-level comparison of traffic safety factors. Use cases include risk modeling for insurance underwriting, policy analysis related to drinking and driving laws, academic research into transportation safety variables, and generating reports aimed at public safety awareness.
Coverage
The data covers all 51 US states and jurisdictions. The time range for the underlying statistics varies slightly, spanning data collected between 2009 and 2012, based on the reporting years of the National Highway Traffic Safety Administration (NHTSA) and the National Association of Insurance Commissioners (NAIC) reports. The expected update frequency is never.

Who Can Use It
- Insurance Analysts: For developing accurate state-specific premium models and assessing loss exposure.
- Public Safety Researchers: To correlate collision rates with specific factors like speeding or alcohol use.
- Journalists: To support articles and stories analysing which states have higher relative risks for drivers, building upon the original context: "Dear Mona, Which State Has The Worst Drivers?".
- Government Policy Makers: To benchmark local safety initiatives against national statistics.
