Violations involving these vehicle models appear to correlate positively with driver age, occupation, and/or lifestyle. For example, the Jaguar XJ and Buick Park Avenue are often driven by mature, experienced drivers who are more focused on comfort and driving experience than on personal expression. In addition, compared to those vehicles with numerous violations, there are more minivans, SUVs, and pickups with low violations. That finding is worthy of a tip-of-the-hat to soccer moms and hard-hat workers, who, day in and day out, are among the safest drivers on the road.

Vehicles that were discontinued for more than 10 years were not included in the analysis. Violations were standardized based on the number of violations per 100,000 miles driven for each model. That standardization accounts for the differences in average annual miles driven by different models. Each vehicle model's violation count per 100,000 miles was compared with the average across all the models to identify the 10 models with the highest and lowest violations, as compared to the average. For example, Hummer drivers were 4.63 times more likely to get a ticket, as compared to the average.
