Age matters behind the wheel — but not how you might expect
Among new drivers, teenagers were better prepared for a state driving test than those in their 20s
One hundred novice drivers — each with less than five hours of driving experience before their first driving lesson — participated in a two-hour lesson focused on car control and traffic maneuvers for a UCLA research project exploring the relationship between new drivers’ skills and four factors.
Students drove on the streets of Los Angeles, ranked by the 2017 INRIX Global Traffic Scorecard as having the worst traffic in the world. The group was evenly split by gender, and the students’ average age was 18.
Following the lesson, the instructor ranked each student’s skills on a four-point scale, in which 1 means the student requires far more instruction and practice before taking the state driving test and 4 indicates the instructor believes the student is prepared to pass the test.
The researchers analyzed the results based on these variables:
Age: Among males, the older the student, the worse his driving skills score. There was a similar trend among female drivers, but it was not as significant.
Gender: Students were asked to rate their confidence in their own driving skills. Although female students on average were less confident than their male counterparts, men and women received almost the same average score from driving instructors.
Sports participation: A history of playing any kind of organized sport was linked to better driving skills among both men and women. Men and women who played sports scored 2.66 and 2.43, respectively, while men and women who had not played organized sports had average scores of 1.94 and 1.60. Previous studies have shown that participating in organized sports improves spatial perception.
Video game experience: Playing video games showed no relationship to driving abilities. The authors expected the opposite, because earlier research has shown that playing action video games improves spatial cognition.
The authors propose that states consider ending mandatory driver’s education for only teens and expanding safety training to new drivers of all ages. If translated into policy, the findings could improve driver training, ultimately reducing traffic accidents and saving lives.
The findings were published in the online edition of the journal PLOS One.
